This is notable because this commit refactors the code, adding a new KM_SLEEP allocation. It is not clear to me whether this should be converted to KM_PUSHPAGE. 3. We had a merge conflict in libzfs_sendrecv.c because of copyright notices. 4. Several small C99 compatibility fixed were made.

* Default device paths
*/
Allow 'zpool replace' to use short device names The 'zpool replace' command would fail when given a short name because unlike on other platforms the short name cannot be deterministically expanded to a single path. Multiple path prefixes must be checked and in addition the partition suffix for whole disks is determined by the prefix. To handle this complexity a zfs_strcmp_pathname() function was added which takes either a short or fully qualified device name. Short names will be expanded using the prefixes in the default import search path, or the ZPOOL_IMPORT_PATH environment variable if it's defined. All posible expansions are then compared against the comparison path. Care is taken to strip redundant slashes to ensure legitimate matches are not missed. In the context of this work the existing zfs_resolve_shortname() function was extended to consider the ZPOOL_IMPORT_PATH when set. The zfs_append_partition() interface was also simplified to take only a single buffer. The vast majority of these changes rework existing Linux specific code which was originally written to accomidate udev. However, there is some minimal cleanup which removes Illumos specific code. This was done to improve readability but the basic flow and intent of the upstream code was maintained. These changes are the logical conclusion of the previos work to adjust the 'zpool import' search behavior, see commit 44867b6a.

Add the ZFS Test Suite Add the ZFS Test Suite and test-runner framework from illumos. This is a continuation of the work done by Turbo Fredriksson to port the ZFS Test Suite to Linux. While this work was originally conceived as a stand alone project integrating it directly with the ZoL source tree has several advantages: * Allows the ZFS Test Suite to be packaged in zfs-test package. * Facilitates easy integration with the CI testing. * Users can locally run the ZFS Test Suite to validate ZFS. This testing should ONLY be done on a dedicated test system because the ZFS Test Suite in its current form is destructive. * Allows the ZFS Test Suite to be run directly in the ZoL source tree enabled developers to iterate quickly during development. * Developers can easily add/modify tests in the framework as features are added or functionality is changed. The tests will then always be in sync with the implementation. Full documentation for how to run the ZFS Test Suite is available in the tests/README.md file. Warning: This test suite is designed to be run on a dedicated test system. It will make modifications to the system including, but not limited to, the following. * Adding new users * Adding new groups * Modifying the following /proc files: * /proc/sys/kernel/core_pattern * /proc/sys/kernel/core_uses_pid * Creating directories under / Notes: * Not all of the test cases are expected to pass and by default these test cases are disabled. The failures are primarily due to assumption made for illumos which are invalid under Linux. * When updating these test cases it should be done in as generic a way as possible so the patch can be submitted back upstream. Most existing library functions have been updated to be Linux aware, and the following functions and variables have been added. * Functions: * is_linux - Used to wrap a Linux specific section. * block_device_wait - Waits for block devices to be added to /dev/. * Variables: Linux Illumos * ZVOL_DEVDIR "/dev/zvol" "/dev/zvol/dsk" * ZVOL_RDEVDIR "/dev/zvol" "/dev/zvol/rdsk" * DEV_DSKDIR "/dev" "/dev/dsk" * DEV_RDSKDIR "/dev" "/dev/rdsk" * NEWFS_DEFAULT_FS "ext2" "ufs" * Many of the disabled test cases fail because 'zfs/zpool destroy' returns EBUSY. This is largely causes by the asynchronous nature of device handling on Linux and is expected, the impacted test cases will need to be updated to handle this. * There are several test cases which have been disabled because they can trigger a deadlock. A primary example of this is to recursively create zpools within zpools. These tests have been disabled until the root issue can be addressed. * Illumos specific utilities such as (mkfile) should be added to the tests/zfs-tests/cmd/ directory. Custom programs required by the test scripts can also be added here. * SELinux should be either is permissive mode or disabled when running the tests. The test cases should be updated to conform to a standard policy. * Redundant test functionality has been removed (zfault.sh). * Existing test scripts (zconfig.sh) should be migrated to use the framework for consistency and ease of testing. * The DISKS environment variable currently only supports loopback devices because of how the ZFS Test Suite expects partitions to be named (p1, p2, etc). Support must be added to generate the correct partition name based on the device location and name. * The ZFS Test Suite is part of the illumos code base at: https://github.com/illumos/illumos-gate/tree/master/usr/src/test Original-patch-by: Turbo Fredriksson <turbo@bayour.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Olaf Faaland <faaland1@llnl.gov> Closes #6 Closes #1534

Increase default udev wait time When creating a new pool, or adding/replacing a disk in an existing pool, partition tables will be automatically created on the devices. Under normal circumstances it will take less than a second for udev to create the expected device files under /dev/. However, it has been observed that if the system is doing heavy IO concurrently udev may take far longer. If you also throw in some cheap dodgy hardware it may take even longer. To prevent zpool commands from failing due to this the default wait time for udev is being increased to 30 seconds. This will have no impact on normal usage, the increase timeout should only be noticed if your udev rules are incorrectly configured.

Fix 'zpool import' detection issues This patch addresses multiple 'zpool import' block device indentification problems which are most likely to occur on a system configured to use blkid, by_vdev paths, multipath and failover. The symptom most commonly observed is the import uses different path names to import the pool than would normally be expected. * When using blkid to identify vdevs the listed devices may be added to the cache in any order. In order to apply the preferred search order heuristic a zfs_path_order() function was added to calculate the order given full path names. * Since it's possible to have multiple block devices with different vdev guids which refer to the same ZPOOL_CONFIG_PATH the slice cache must be indexed by guid and name. By avoiding collisions the preferred ordering can be maintaining even when multiple block devices claim the same ZPOOL_CONFIG_PATH. The preferred sorting by partition was never benefitial for a Linux system and was removed as part of this change. * When adding entries to the blkid cache avl_find/avl_insert are used instead of avl_add because collisions are possible and must be handled gracefully. * For pools using multipath devices there are, at a minimum, three devices where a vdev label may be read. They are the dm-* device and each underlying /dev/sd* device. Due to the way the block cache is implemented each of these devices may have a different cached copy of the vdev label. This can result in "ghost pools" which appear to persist even after a 'zpool labelclear' has been done to the dm-* device. In order to prevent this the vdev label is read with O_DIRECT in order to bypass any caching to get the on-disk version. * When opening a block device verify that vdev guid read from the disk matches the expected vdev guid. This allows for bad labels to be filtered out. Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #5359

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes. Add a missing call to fnvlist_free(nvl) in log_internal() that was added in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time (zfsonlinux/zfs@9e11c73) because it depended on future work.

Add -gLp to zpool subcommands for alt vdev names The following options have been added to the zpool add, iostat, list, status, and split subcommands. The default behavior was not modified, from zfs(8). -g Display vdev GUIDs instead of the normal short device names. These GUIDs can be used in-place of device names for the zpool detach/off‐ line/remove/replace commands. -L Display real paths for vdevs resolving all symbolic links. This can be used to lookup the current block device name regardless of the /dev/disk/ path used to open it. -p Display full paths for vdevs instead of only the last component of the path. This can be used in conjunction with the -L flag. This behavior may also be enabled using the following environment variables. ZPOOL_VDEV_NAME_GUID ZPOOL_VDEV_NAME_FOLLOW_LINKS ZPOOL_VDEV_NAME_PATH This change is based on worked originally started by Richard Yao to add a -g option. Then extended by @ilovezfs to add a -L option for openzfsonosx. Those changes have been merged, re-factored, a -p option added and extended to all relevant zpool subcommands.

Turn on/off enclosure slot fault LED even when disk isn't present Previously when a drive faulted, the statechange-led.sh script would lookup the drive's LED sysfs entry in /sys/block/sd*/device/enclosure_device, and turn it on. During testing we noticed that if you pulled out a drive, or if the drive was so badly broken that it no longer appeared to Linux, that the /sys/block/sd* path would be removed, and the script could not lookup the LED entry. To fix this, this patch looks up the disks's more persistent "/sys/class/enclosure/X:X:X:X/Slot N" LED sysfs path at pool import. It then passes that path to the statechange-led script to use, rather than having the script look it up on the fly. This allows the script to turn on/off the slot LEDs even when the drive is missing.

This behavior is consistent with the upstream OpenZFS code and the test cases depend on it. The actual implementation differs slightly due to device naming conventions on Linux. - auto_online_001_pos, auto_replace_001_pos and add-o_ashift test cases updated to expect failure when no label exists. - read_efi_label() and zpool_label_disk_check() are read-only operations and should use O_RDONLY at open time to enforce this. - zpool_label_disk() and zpool_relabel_disk() write the partition information using O_DIRECT an fsync() and page cache invalidation to ensure a consistent view of the device. - dump_label() in zdb should invalidate the page cache in order to get the authoritative label from disk.

Multipath autoreplace, control enclosure LEDs, event rate limiting 1. Enable multipath autoreplace support for FMA. This extends FMA autoreplace to work with multipath disks. This requires libdevmapper to be installed at build time. 2. Turn on/off fault LEDs when VDEVs become degraded/faulted/online Set ZED_USE_ENCLOSURE_LEDS=1 in zed.rc to have ZED turn on/off the enclosure LED for a drive when a drive becomes FAULTED/DEGRADED. Your enclosure must be supported by the Linux SES driver for this to work. The enclosure LED scripts work for multipath devices as well. The scripts will clear the LED when the fault is cleared. 3.

Introduce zpool_get_prop_literal interface This change introduces zpool_get_prop_literal. It's an expanded version of zpool_get_prop taking one additional boolean parameter. With this parameter set to B_FALSE it will behave identically to zpool_get_prop. Setting it to B_TRUE will return full precision numbers for the following properties: ZPOOL_PROP_SIZE ZPOOL_PROP_ALLOCATED ZPOOL_PROP_FREE ZPOOL_PROP_FREEING ZPOOL_PROP_EXPANDSZ ZPOOL_PROP_ASHIFT Also introduced is a wrapper function for zpool_get_prop making it use zpool_get_prop_literal in the background.

Add generic errata infrastructure From time to time it may be necessary to inform the pool administrator about an errata which impacts their pool. These errata will by shown to the administrator through the 'zpool status' and 'zpool import' output as appropriate. The errata must clearly describe the issue detected, how the pool is impacted, and what action should be taken to resolve the situation. Additional information for each errata will be provided at http://zfsonlinux.org/msg/ZFS-8000-ER. To accomplish the above this patch adds the required infrastructure to allow the kernel modules to notify the utilities that an errata has been detected. This is done through the ZPOOL_CONFIG_ERRATA uint64_t which has been added to the pool configuration nvlist. To add a new errata the following changes must be made: * A new errata identifier must be assigned by adding a new enum value to the zpool_errata_t type. New enums must be added to the end to preserve the existing ordering. * Code must be added to detect the issue. This does not strictly need to be done at pool import time but doing so will make the errata visible in 'zpool import' as well as 'zpool status'. Once detected the spa->spa_errata member should be set to the new enum. * If possible code should be added to clear the spa->spa_errata member once the errata has been resolved. * The show_import() and status_callback() functions must be updated to include an informational message describing the errata. This should include an action message describing what an administrator should do to address the errata. * The documentation at http://zfsonlinux.org/msg/ZFS-8000-ER must be updated to describe the errata. This space can be used to provide as much additional information as needed to fully describe the errata.

Require libblkid Historically libblkid support was detected as part of configure and optionally enabled. This was done because at the time support for detecting ZFS pool vdevs had just be added to libblkid and those updated packages were not yet part of many distributions. This is no longer the case and any reasonably current distribution will ship a version of libblkid which can detect ZFS pool vdevs. This patch makes libblkid mandatory at build time and libblkid the preferred method of scanning for ZFS pools. For distributions which include a modern version of libblkid there is no change in behavior. Explicitly scanning the default search paths is still supported and can be enabled with the '-s' command line option. Additionally making libblkid mandatory means that the 'zpool create' command can reliably detect if a specified device has an existing non-ZFS filesystem (ext4, xfs) and print a warning.

This can be used in conjunction with the -L flag. This behavior may also be enabled using the following environment variables. ZPOOL_VDEV_NAME_GUID ZPOOL_VDEV_NAME_FOLLOW_LINKS ZPOOL_VDEV_NAME_PATH This change is based on worked originally started by Richard Yao to add a -g option. Then extended by @ilovezfs to add a -L option for openzfsonosx. Those changes have been merged, re-factored, a -p option added and extended to all relevant zpool subcommands.

Replace zpool_events_next() "block" parm w/ "flags" zpool_events_next() can be called in blocking mode by specifying a non-zero value for the "block" parameter. However, the design of the ZFS Event Daemon (zed) requires additional functionality from zpool_events_next(). Instead of adding additional arguments to the function, it makes more sense to use flags that can be bitwise-or'd together. This commit replaces the zpool_events_next() int "block" parameter with an unsigned bitwise "flags" parameter. It also defines ZEVENT_NONE to specify the default behavior. Since non-blocking mode can be specified with the existing ZEVENT_NONBLOCK flag, the default behavior becomes blocking mode. This, in effect, inverts the previous use of the "block" parameter. Existing callers of zpool_events_next() have been modified to check for the ZEVENT_NONBLOCK flag.

Add linux events This topic branch leverages the Solaris style FMA call points in ZFS to create a user space visible event notification system under Linux. This new system is called zevent and it unifies all previous Solaris style ereports and sysevent notifications. Under this Linux specific scheme when a sysevent or ereport event occurs an nvlist describing the event is created which looks almost exactly like a Solaris ereport. These events are queued up in the kernel when they occur and conditionally logged to the console. It is then up to a user space application to consume the events and do whatever it likes with them. To make this possible the existing /dev/zfs ABI has been extended with two new ioctls which behave as follows. * ZFS_IOC_EVENTS_NEXT Get the next pending event. The kernel will keep track of the last event consumed by the file descriptor and provide the next one if available. If no new events are available the ioctl() will block waiting for the next event. This ioctl may also be called in a non-blocking mode by setting zc.zc_guid = ZEVENT_NONBLOCK. In the non-blocking case if no events are available ENOENT will be returned. It is possible that ESHUTDOWN will be returned if the ioctl() is called while module unloading is in progress. And finally ENOMEM may occur if the provided nvlist buffer is not large enough to contain the entire event. * ZFS_IOC_EVENTS_CLEAR Clear are events queued by the kernel. The kernel will keep a fairly large number of recent events queued, use this ioctl to clear the in kernel list. This will effect all user space processes consuming events. The zpool command has been extended to use this events ABI with the 'events' subcommand. You may run 'zpool events -v' to output a verbose log of all recent events. This is very similar to the Solaris 'fmdump -ev' command with the key difference being it also includes what would be considered sysevents under Solaris. You may also run in follow mode with the '-f' option. To clear the in kernel event queue use the '-c' option. $ sudo cmd/zpool/zpool events -fv TIME CLASS May 13 2010 16:31:15.777711000 ereport.fs.zfs.config.sync class = "ereport.fs.zfs.config.sync" ena = 0x40982b7897700001 detector = (embedded nvlist) version = 0x0 scheme = "zfs" pool = 0xed976600de75dfa6 (end detector) time = 0x4bec8bc3 0x2e5aed98 pool = "zpios" pool_guid = 0xed976600de75dfa6 pool_context = 0x0 While the 'zpool events' command is handy for interactive debugging it is not expected to be the primary consumer of zevents. This ABI was primarily added to facilitate the addition of a user space monitoring daemon. This daemon would consume all events posted by the kernel and based on the type of event perform an action. For most events simply forwarding them on to syslog is likely enough. But this interface also cleanly allows for more sophisticated actions to be taken such as generating an email for a failed drive.

Add zpool_events_seek() functionality The ZFS_IOC_EVENTS_SEEK ioctl was added to allow user space callers to seek around the zevent file descriptor by EID. When a specific EID is passed and it exists the cursor will be positioned there. If the EID is no longer cached by the kernel ENOENT is returned. The caller may also pass ZEVENT_SEEK_START or ZEVENT_SEEK_END to seek to those respective locations.

Linux compat 2.6.39: mount_nodev() The .get_sb callback has been replaced by a .mount callback in the file_system_type structure. When using the new interface the caller must now use the mount_nodev() helper. Unfortunately, the new interface no longer passes the vfsmount down to the zfs layers. This poses a problem for the existing implementation because we currently save this pointer in the super block for latter use. It provides our only entry point in to the namespace layer for manipulating certain mount options. This needed to be done originally to allow commands like 'zfs set atime=off tank' to work properly. It also allowed me to keep more of the original Solaris code unmodified. Under Solaris there is a 1-to-1 mapping between a mount point and a file system so this is a fairly natural thing to do. However, under Linux they many be multiple entries in the namespace which reference the same filesystem. Thus keeping a back reference from the filesystem to the namespace is complicated. Rather than introduce some ugly hack to get the vfsmount and continue as before. I'm leveraging this API change to update the ZFS code to do things in a more natural way for Linux. This has the upside that is resolves the compatibility issue for the long term and fixes several other minor bugs which have been reported. This commit updates the code to remove this vfsmount back reference entirely. All modifications to filesystem mount options are now passed in to the kernel via a '-o remount'. This is the expected Linux mechanism and allows the namespace to properly handle any options which apply to it before passing them on to the file system itself. Aside from fixing the compatibility issue, removing the vfsmount has had the benefit of simplifying the code. This change which fairly involved has turned out nicely.

Speed up 'zfs list -t snapshot -o name -s name' FreeBSD #xxx: Dramatically optimize listing snapshots when user requests only snapshot names and wants to sort them by name, ie. when executes: # zfs list -t snapshot -o name -s name Because only name is needed we don't have to read all snapshot properties. Below you can find how long does it take to list 34509 snapshots from a single disk pool before and after this change with cold and warm cache: before: # time zfs list -t snapshot -o name -s name > /dev/null cold cache: 525s warm cache: 218s after: # time zfs list -t snapshot -o name -s name > /dev/null cold cache: 1.7s warm cache: 1.1s NOTE: This patch only appears in FreeBSD. If/when Illumos picks up the change we may want to drop this patch and adopt their version. However, for now this addresses a real issue. Ported-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #450

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes. Add a missing call to fnvlist_free(nvl) in log_internal() that was added in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time (zfsonlinux/zfs@9e11c73) because it depended on future work.

Volumes, like filesystems, are limited by the zfs_max_recordsize=1M module option. * By default the maximum record size is limited to 1M by the module option zfs_max_recordsize. This value may be safely increased up to 16M which is the largest block size supported by the on-disk format. At the moment, 1M blocks clearly offer a significant performance improvement but the benefits of going beyond this for the majority of workloads are less clear. * The illumos version of this patch increased DMU_MAX_ACCESS to 32M. This was determined not to be large enough when using 16M blocks because the zfs_make_xattrdir() function will fail (EFBIG) when assigning a TX. This was immediately observed under Linux because all newly created files must have a security xattr created and that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M. * On 32-bit platforms a hard limit of 1M is set for blocks due to the limited virtual address space. We should be able to relax this one the ABD patches are merged. Ported-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #354

This is notable because this commit refactors the code, adding a new KM_SLEEP allocation. It is not clear to me whether this should be converted to KM_PUSHPAGE. 3. We had a merge conflict in libzfs_sendrecv.c because of copyright notices. 4. Several small C99 compatibility fixed were made.

extern boolean_t zfs_bookmark_exists(const char *path);
Allow 'zpool replace' to use short device names The 'zpool replace' command would fail when given a short name because unlike on other platforms the short name cannot be deterministically expanded to a single path. Multiple path prefixes must be checked and in addition the partition suffix for whole disks is determined by the prefix. To handle this complexity a zfs_strcmp_pathname() function was added which takes either a short or fully qualified device name. Short names will be expanded using the prefixes in the default import search path, or the ZPOOL_IMPORT_PATH environment variable if it's defined. All posible expansions are then compared against the comparison path. Care is taken to strip redundant slashes to ensure legitimate matches are not missed. In the context of this work the existing zfs_resolve_shortname() function was extended to consider the ZPOOL_IMPORT_PATH when set. The zfs_append_partition() interface was also simplified to take only a single buffer. The vast majority of these changes rework existing Linux specific code which was originally written to accomidate udev. However, there is some minimal cleanup which removes Illumos specific code. This was done to improve readability but the basic flow and intent of the upstream code was maintained. These changes are the logical conclusion of the previos work to adjust the 'zpool import' search behavior, see commit 44867b6a.

Add helper functions for manipulating device names This change adds two helper functions for working with vdev names and paths. zfs_resolve_shortname() resolves a shorthand vdev name to an absolute path of a file in /dev, /dev/disk/by-id, /dev/disk/by-label, /dev/disk/by-path, /dev/disk/by-uuid, /dev/disk/zpool. This was previously done only in the function is_shorthand_path(), but we need a general helper function to implement shorthand names for additional zpool subcommands like remove. is_shorthand_path() is accordingly updated to call the helper function. There is a minor change in the way zfs_resolve_shortname() tests if a file exists. is_shorthand_path() effectively used open() and stat64() to test for file existence, since its scope includes testing if a device is a whole disk and collecting file status information. zfs_resolve_shortname(), on the other hand, only uses access() to test for existence and leaves it to the caller to perform any additional file operations. This seemed like the most general and lightweight approach, and still preserves the semantics of is_shorthand_path(). zfs_append_partition() appends a partition suffix to a device path. This should be used to generate the name of a whole disk as it is stored in the vdev label. The user-visible names of whole disks do not contain the partition information, while the name in the vdev label does. The code was lifted from the function make_disks(), which now just calls the helper function. Again, having a helper function to do this supports general handling of shorthand names in the user interface. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>

extern int zfs_strcmp_pathname(char *name, char *cmp_name, int wholedisk);
Fix 'zpool import' detection issues This patch addresses multiple 'zpool import' block device indentification problems which are most likely to occur on a system configured to use blkid, by_vdev paths, multipath and failover. The symptom most commonly observed is the import uses different path names to import the pool than would normally be expected. * When using blkid to identify vdevs the listed devices may be added to the cache in any order. In order to apply the preferred search order heuristic a zfs_path_order() function was added to calculate the order given full path names. * Since it's possible to have multiple block devices with different vdev guids which refer to the same ZPOOL_CONFIG_PATH the slice cache must be indexed by guid and name. By avoiding collisions the preferred ordering can be maintaining even when multiple block devices claim the same ZPOOL_CONFIG_PATH. The preferred sorting by partition was never benefitial for a Linux system and was removed as part of this change. * When adding entries to the blkid cache avl_find/avl_insert are used instead of avl_add because collisions are possible and must be handled gracefully. * For pools using multipath devices there are, at a minimum, three devices where a vdev label may be read. They are the dm-* device and each underlying /dev/sd* device. Due to the way the block cache is implemented each of these devices may have a different cached copy of the vdev label. This can result in "ghost pools" which appear to persist even after a 'zpool labelclear' has been done to the dm-* device. In order to prevent this the vdev label is read with O_DIRECT in order to bypass any caching to get the on-disk version. * When opening a block device verify that vdev guid read from the disk matches the expected vdev guid. This allows for bad labels to be filtered out. Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #5359

Print mount/umount errors Because we are dependent of the system mount/umount utilities to ensure correct mtab locking, we should not suppress their error output. During a successful mount/umount they will be silent, but during a failure the error message they print is the only sure way to know why a mount failed. This is because the (u)mount(8) return code does not contain the result of the system call issued. The only way to clearly idenify why thing failed is to rely on the error message printed by the tool. Longer term once libmount is available we can issue the mount/umount system calls within the tool and still be ensured correct mtab locking. Closed #107

Prebaked scripts for zpool status/iostat -c This patch updates the "zpool status/iostat -c" commands to only run "pre-baked" scripts from the /etc/zfs/zpool.d directory (or wherever you install to). The scripts can only be run from -c as an unprivileged user (unless the ZPOOL_SCRIPTS_AS_ROOT environment var is set by root). This was done to encourage scripts to be written is such a way that normal users can use them, and to be cautious. If your script needs to run a privileged command, consider adding the appropriate line in /etc/sudoers. See zpool(8) for an example of how to do this. The patch also allows the scripts to output custom column names. If the script outputs a line like: name=value then "name" is used for the column name, and "value" is its value. Multiple columns can be specified by outputting multiple lines. Column names and values can have spaces. If the value is empty, a dash (-) is printed instead. After all the "name=value" lines are read (if any), zpool will take the next the next line of output (if any) and print it without a column header. After that, no more lines will be processed. This can be useful for printing errors. Lastly, this patch also disables the -c option with the latency and request size histograms, since it produced awkward output and made the code harder to maintain.

Check all vdev labels in 'zpool import' When using 'zpool import' to scan for available pools prefer vdev names which reference vdevs with more valid labels. There should be two labels at the start of the device and two labels at the end of the device. If labels are missing then the device has been damaged or is in some other way incomplete. Preferring names with fully intact labels helps weed out bad paths and improves the likelihood of being able to import the pool. This behavior only applies when scanning /dev/ for valid pools. If a cache file exists the pools described by the cache file will be used.

Add -c to zpool iostat & status to run command This patch adds a command (-c) option to zpool status and zpool iostat. The -c option allows you to run an arbitrary command on each vdev and display the first line of output in zpool status/iostat. The environment vars VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path" before running the command. For device mapper, multipath, or partitioned vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful if the command you're running requires a /dev/sd* device. The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device instead of using libdevmapper. This not only removes the libdevmapper requirement at build time, but also allows you to resolve device mapper devices without being root. This means that UDEV_UPATH get set correctly when running zpool status/iostat as an unprivileged user. Example: $ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH' NAME STATE READ WRITE CKSUM mypool ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 mpatha ONLINE 0 0 0 I am /dev/mapper/mpatha, /dev/sdc sdb ONLINE 0 0 0 I am /dev/sdb1, /dev/sdb Reviewed-by: Giuseppe Di Natale <dinatale2@llnl.gov> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Tony Hutter <hutter2@llnl.gov> Closes #5368
