Details about the motivation of this feature and its usage can
be found in this blogpost:
https://sdimitro.github.io/post/zpool-checkpoint/
A lightning talk of this feature can be found here:
https://www.youtube.com/watch?v=fPQA8K40jAM
Implementation details can be found in big block comment of
spa_checkpoint.c
Side-changes that are relevant to this commit but not explained
elsewhere:
* renames members of "struct metaslab trees to be shorter without
losing meaning
* space_map_{alloc,truncate}() accept a block size as a
parameter. The reason is that in the current state all space
maps that we allocate through the DMU use a global tunable
(space_map_blksz) which defauls to 4KB. This is ok for metaslab
space maps in terms of bandwirdth since they are scattered all
over the disk. But for other space maps this default is probably
not what we want. Examples are device removal's vdev_obsolete_sm
or vdev_chedkpoint_sm from this review. Both of these have a
1:1 relationship with each vdev and could benefit from a bigger
block size.
Porting notes:
* The part of dsl_scan_sync() which handles async destroys has
been moved into the new dsl_process_async_destroys() function.
* Remove "VERIFY(!(flags & FWRITE))" in "kernel.c" so zhack can write
to block device backed pools.
* ZTS:
* Fix get_txg() in zpool_sync_001_pos due to "checkpoint_txg".
* Don't use large dd block sizes on /dev/urandom under Linux in
checkpoint_capacity.
* Adopt Delphix-OS's setting of 4 (spa_asize_inflation =
SPA_DVAS_PER_BP + 1) for the checkpoint_capacity test to speed
its attempts to fill the pool
* Create the base and nested pools with sync=disabled to speed up
the "setup" phase.
* Clear labels in test pool between checkpoint tests to avoid
duplicate pool issues.
* The import_rewind_device_replaced test has been marked as "known
to fail" for the reasons listed in its DISCLAIMER.
* New module parameters:
zfs_spa_discard_memory_limit,
zfs_remove_max_bytes_pause (not documented - debugging only)

OpenZFS 7614 - zfs device evacuation/removal
OpenZFS 9064 - remove_mirror should wait for device removal to complete
This project allows top-level vdevs to be removed from the storage pool
with "zpool remove", reducing the total amount of storage in the pool.
This operation copies all allocated regions of the device to be removed
onto other devices, recording the mapping from old to new location.
After the removal is complete, read and free operations to the removed
(now "indirect") vdev must be remapped and performed at the new location
on disk. The indirect mapping table is kept in memory whenever the pool
is loaded, so there is minimal performance overhead when doing operations
on the indirect vdev.
The size of the in-memory mapping table will be reduced when its entries
become "obsolete" because they are no longer used by any block pointers
in the pool. An entry becomes obsolete when all the blocks that use
it are freed. An entry can also become obsolete when all the snapshots
that reference it are deleted, and the block pointers that reference it
have been "remapped" in all filesystems/zvols (and clones). Whenever an
indirect block is written, all the block pointers in it will be "remapped"
to their new (concrete) locations if possible. This process can be
accelerated by using the "zfs remap" command to proactively rewrite all
indirect blocks that reference indirect (removed) vdevs.
Note that when a device is removed, we do not verify the checksum of
the data that is copied. This makes the process much faster, but if it
were used on redundant vdevs (i.e. mirror or raidz vdevs), it would be
possible to copy the wrong data, when we have the correct data on e.g.
the other side of the mirror.
At the moment, only mirrors and simple top-level vdevs can be removed
and no removal is allowed if any of the top-level vdevs are raidz.
Porting Notes:
* Avoid zero-sized kmem_alloc() in vdev_compact_children().
The device evacuation code adds a dependency that
vdev_compact_children() be able to properly empty the vdev_child
array by setting it to NULL and zeroing vdev_children. Under Linux,
kmem_alloc() and related functions return a sentinel pointer rather
than NULL for zero-sized allocations.
* Remove comment regarding "mpt" driver where zfs_remove_max_segment
is initialized to SPA_MAXBLOCKSIZE.
Change zfs_condense_indirect_commit_entry_delay_ticks to
zfs_condense_indirect_commit_entry_delay_ms for consistency with
most other tunables in which delays are specified in ms.
* ZTS changes:
Use set_tunable rather than mdb
Use zpool sync as appropriate
Use sync_pool instead of sync
Kill jobs during test_removal_with_operation to allow unmount/export
Don't add non-disk names such as "mirror" or "raidz" to $DISKS
Use $TEST_BASE_DIR instead of /tmp
Increase HZ from 100 to 1000 which is more common on Linux
removal_multiple_indirection.ksh
Reduce iterations in order to not time out on the code
coverage builders.
removal_resume_export:
Functionally, the test case is correct but there exists a race
where the kernel thread hasn't been fully started yet and is
not visible. Wait for up to 1 second for the removal thread
to be started before giving up on it. Also, increase the
amount of data copied in order that the removal not finish
before the export has a chance to fail.
* MMP compatibility, the concept of concrete versus non-concrete devices
has slightly changed the semantics of vdev_writeable(). Update
mmp_random_leaf_impl() accordingly.
* Updated dbuf_remap() to handle the org.zfsonlinux:large_dnode pool
feature which is not supported by OpenZFS.
* Added support for new vdev removal tracepoints.
* Test cases removal_with_zdb and removal_condense_export have been
intentionally disabled. When run manually they pass as intended,
but when running in the automated test environment they produce
unreliable results on the latest Fedora release.
They may work better once the upstream pool import refectoring is
merged into ZoL at which point they will be re-enabled.

This patch ports Joyent's JSON nvlist library from illumos to enable
easy JSON printing of channel program output nvlist. To keep the
delta small I also took advantage of the fact that printing in

Project quota is a new ZFS system space/object usage accounting
and enforcement mechanism. Similar as user/group quota, project
quota is another dimension of system quota. It bases on the new
object attribute - project ID.
Project ID is a numerical value to indicate to which project an
object belongs. An object only can belong to one project though
you (the object owner or privileged user) can change the object
project ID via 'chattr -p' or 'zfs project [-s] -p' explicitly.
The object also can inherit the project ID from its parent when
created if the parent has the project inherit flag (that can be
set via 'chattr +P' or 'zfs project -s [-p]').
By accounting the spaces/objects belong to the same project, we
can know how many spaces/objects used by the project. And if we
set the upper limit then we can control the spaces/objects that
are consumed by such project. It is useful when multiple groups
and users cooperate for the same project, or a user/group needs
to participate in multiple projects.
Support the following commands and functionalities:
zfs set projectquota@project
zfs set projectobjquota@project
zfs get projectquota@project
zfs get projectobjquota@project
zfs get projectused@project
zfs get projectobjused@project
zfs projectspace
zfs allow projectquota
zfs allow projectobjquota
zfs allow projectused
zfs allow projectobjused
zfs unallow projectquota
zfs unallow projectobjquota
zfs unallow projectused
zfs unallow projectobjused
chattr +/-P
chattr -p project_id
lsattr -p
This patch also supports tree quota based on the project quota via
"zfs project" commands set as following:
zfs project [-d|-r] <file|directory ...>
zfs project -C [-k] [-r] <file|directory ...>
zfs project -c [-0] [-d|-r] [-p id] <file|directory ...>
zfs project [-p id] [-r] [-s] <file|directory ...>
For "df [-i] $DIR" command, if we set INHERIT (project ID) flag on
the $DIR, then the proejct [obj]quota and [obj]used values for the
$DIR's project ID will be shown as the total/free (avail) resource.
Keep the same behavior as EXT4/XFS does.

There are some issues in the zdb -R decompression implementation.
The first is that ZLE can easily decompress non-ZLE streams. So we add
ZDB_NO_ZLE env to make zdb skip ZLE.
The second is the random bytes appended to pabd, pbuf2 stuff. This serve
no purpose at all, those bytes shouldn't be read during decompression
anyway. Instead, we randomize lbuf2, so that we can make sure
decompression fill exactly to lsize by bcmp lbuf and lbuf2.
The last one is the condition to detect fail is wrong.

We want to be able to run channel programs outside of synching
context. This would greatly improve performance for channel programs
that just gather information, as they won't have to wait for synching
context anymore.
=== What is implemented?
This feature introduces the following:
- A new command line flag in "zfs program" to specify our intention
to run in open context. (The -n option)
- A new flag/option within the channel program ioctl which selects
the context.
- Appropriate error handling whenever we try a channel program in
open-context that contains zfs.sync* expressions.
- Documentation for the new feature in the manual pages.
=== How do we handle zfs.sync functions in open context?
When such a function is found by the interpreter and we are running
in open context we abort the script and we spit out a descriptive
runtime error. For example, given the script below ...
arg = ...
fs = arg["argv"][1]
err = zfs.sync.destroy(fs)
msg = "destroying " .. fs .. " err=" .. err
return msg
if we run it in open context, we will get back the following error:
Channel program execution failed:
[string "channel program"]:3: running functions from the zfs.sync
submodule requires passing sync=TRUE to lzc_channel_program()
(i.e. do not specify the "-n" command line argument)
stack traceback:
[C]: in function 'destroy'
[string "channel program"]:3: in main chunk
=== What about testing?
We've introduced new wrappers for all channel program tests that
run each channel program as both (startard & open-context) and
expect the appropriate behavior depending on the program using
the zfs.sync module.

When we know which devices have the pool we are looking for, sometime

take a lot of time if you have hundreds of disks.
This patch allows option -d <dev_path> to zpool import. You can have
multiple pairs of -d <dev_path>, and zpool import will only search

The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file. By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely. Functionally an empty cache file is
treated the same as a missing cache file. This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.
The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.
The zfs-import-* systemd service files were not updated to use
ConditionFileNotEmpty in place of ConditionPathExists. This
means that after exporting all pools and rebooting new pools
will not the scanned for on the next boot. This small change
should not impact normal usage since pools are not exported
as part of a normal shutdown.

This change incorporates three major pieces:
The first change is a keystore that manages wrapping
and encryption keys for encrypted datasets. These
commands mostly involve manipulating the new
DSL Crypto Key ZAP Objects that live in the MOS. Each
encrypted dataset has its own DSL Crypto Key that is
protected with a user's key. This level of indirection
allows users to change their keys without re-encrypting
their entire datasets. The change implements the new
subcommands "zfs load-key", "zfs unload-key" and
"zfs change-key" which allow the user to manage their
encryption keys and settings. In addition, several new
flags and properties have been added to allow dataset
creation and to make mounting and unmounting more
convenient.
The second piece of this patch provides the ability to
encrypt, decyrpt, and authenticate protected datasets.
Each object set maintains a Merkel tree of Message
Authentication Codes that protect the lower layers,
similarly to how checksums are maintained. This part
impacts the zio layer, which handles the actual
encryption and generation of MACs, as well as the ARC
and DMU, which need to be able to handle encrypted
buffers and protected data.
The last addition is the ability to do raw, encrypted
sends and receives. The idea here is to send raw
encrypted and compressed data and receive it exactly
as is on a backup system. This means that the dataset
on the receiving system is protected using the same
user key that is in use on the sending side. By doing
so, datasets can be efficiently backed up to an
untrusted system without fear of data being
compromised.

Turning the multihost property on requires that a hostid be set to allow
ZFS to determine when a foreign system is attemping to import a pool.
The error message instructing the user to set a hostid refers to
genhostid(1).
Genhostid(1) is not available on SUSE Linux. This commit adds a script
modeled after genhostid(1) for those users.
Zgenhostid checks for an /etc/hostid file; if it does not exist, it
creates one and stores a value. If the user has provided a hostid as an
argument, that value is used. Otherwise, a random hostid is generated
and stored.
This differs from the CENTOS 6/7 versions of genhostid, which overwrite
the /etc/hostid file even though their manpages state otherwise.
A man page for zgenhostid is added. The one for genhostid is in (1), but
I put zgenhostid in (8) because I believe it's more appropriate.
The mmp tests are modified to use zgenhostid to set the hostid instead
of using the spl_hostid module parameter. zgenhostid will not replace
an existing /etc/hostid file, so new mmp_clear_hostid calls are
required.

Document the existence of `createtxg` and `guid` native properties
in man pages and zfs command output.
One of the great features of ZFS is incremental replication of
snapshots, possibly between pools on different machines.
Shell scripts are commonly used to auomate this procedure. They have to
find the most recent common snapshot between both sides and then
perform incremental send & recv.
Currently, scripts rely on the sorting order of `zfs list`, which
defaults to `createtxg`, and the assumption that snapshot names on
either side do not change.
By making `createtxg` and `guid` part of the public ZFS interface,
scripts are enabled to use
a) `createtxg` to determine the logical & temporal order of snapshots
(the creation property is not an equivalent substitute since
multiple snapshots may be created within one second)
b) `guid` to uniquely identify a snapshot, independent of its current
display name
This has the potential of making scripts safer and correct.

This commit allow higher ashift values (up to 16) in 'zpool create'
The ashift value was previously limited to 13 (8K block) in b41c990
because the limited number of uberblocks we could fit in the
statically sized (128K) vdev label ring buffer could prevent the
ability the safely roll back a pool to recover it.
Since b02fe35 the largest uberblock size we support is 8K: this
allow us to store a minimum number of 16 uberblocks in the vdev
label, even with higher ashift values.
Additionally change 'ashift' pool property behaviour: if set it will
be used as the default hint value in subsequent vdev operations
('zpool add', 'attach' and 'replace'). A custom ashift value can still
be specified from the command line, if desired.
Finally, fix a bug in add-o_ashift.ksh caused by a missing variable.

Porting Notes:
- Most of 7252 was already picked up during ABD work. This
commit represents the gap from the final commit to openzfs.
- Fixed split_large_blocks check in do_dump()
- An alternate version of the write_compressible() function was
implemented for Linux which does not depend on fio. The behavior
of fio differs significantly based on the exact version.
- mkholes was replaced with truncate for Linux.

OpenZFS-commit: https://github.com/openzfs/openzfs/commit/5602294Closes#6067
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.

The current implementation for allowing nfs to access snapdir is very buggy.
It uses a special fh for snapdirs, such that the next time nfsd does
fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd
never knows it cross a mountpoint.
The problem is that nfsd will not hold a reference on the vfsmount of the
snapshot. This cause auto unmounter to unmount the snapshot even though nfs is
still holding dentries in it.
To fix this, we return the inode for the snapdirs themselves. However, we also
trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate
and see the mountpoint and do crossmnt.
Because nfsd will now be aware that these are different filesystems users
must add crossmnt to their export options to access snapshot directories.

For zdb -l, detect when the configuration nvlist in some label l (l>0)
is the same as a configuration already dumped. If so, do not dump it.
Make a similar check when dumping Uberblocks for zdb -lu. Check whether
a label already dumped contains an identical Uberblock. If so, do not
dump the Uberblock.
When dumping a configuration or Uberblock, state which labels it is
found in (0-3), for example: labels = 1 2 3
Detecting redundant uberblocks or configurations is accomplished by
calculating checksums of the uberblocks and the packed nvlists
containing the configuration.
If there is nothing unique to be dumped for a label (ie the
configuration and uberblocks have checksums matching those already
dumped) print nothing for that label.
With additional l's or u's, increase verbosity as follows:
-l Dump each unique configuration only once.
Indicate which labels it appears in.
-ll In addition, dump label space usage stats.
-lll Dump every configuration, unique or not.
-u Dump each unique, valid, uberblock only once.
Indicate which labels it appears in.
-uu In addition, state which slots are invalid.
-uuu Dump every uberblock, unique or not.
-uuuu Dump the uberblock blockpointer (used to be -uuu)
Make exit values conform to the manual page. Failing to unpack a
configuration nvlist is considered an error, as well as failing to open
or read from the device.
Add three tests, zdb_00{3,4,5}_pos to verify the above functionality.

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
