Initial zio delay timing While there is no right maximum timeout for a disk IO we can start laying the ground work to measure how long they do take in practice. This change simply measures the IO time and if it exceeds 30s an event is posted for 'zpool events'. This value was carefully selected because for sd devices it implies that at least one timeout (SD_TIMEOUT) has occured. Unfortunately, even with FAILFAST set we may retry and request and not get an error. This behavior is strongly dependant on the device driver and how it is hooked in to the scsi error handling stack. However by setting the limit at 30s we can log the event even if no error was returned. Slightly longer term we can start recording these delays perhaps as a simple power-of-two histrogram. This histogram can then be reported as part of the 'zpool status' command when given an command line option. None of this code changes the internal behavior of ZFS. Currently it is simply for reporting excessively long delays.

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 automatic hot spare functionality When a vdev starts getting I/O or checksum errors it is now possible to automatically rebuild to a hot spare device. To cleanly support this functionality in a shell script some additional information was added to all zevent ereports which include a vdev. This covers both io and checksum zevents but may be used but other scripts. In the Illumos FMA solution the same information is required but it is retrieved through the libzfs library interface. Specifically the following members were added: vdev_spare_paths - List of vdev paths for all hot spares. vdev_spare_guids - List of vdev guids for all hot spares. vdev_read_errors - Read errors for the problematic vdev vdev_write_errors - Write errors for the problematic vdev vdev_cksum_errors - Checksum errors for the problematic vdev. By default the required hot spare scripts are installed but this functionality is disabled. To enable hot sparing uncomment the ZED_SPARE_ON_IO_ERRORS and ZED_SPARE_ON_CHECKSUM_ERRORS in the /etc/zfs/zed.d/zed.rc configuration file. These scripts do no add support for the autoexpand property. At a minimum this requires adding a new udev rule to detect when a new device is added to the system. It also requires that the autoexpand policy be ported from Illumos, see: https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/syseventd/modules/zfs_mod/zfs_mod.c Support for detecting the correct name of a vdev when it's not a whole disk was added by Turbo Fredriksson.

Generate zevents for speculative and soft errors By default the Solaris code does not log speculative or soft io errors in either 'zpool status' or post an event. Under Linux we don't want to change the expected behavior of 'zpool status' so these io errors are still suppressed there. However, since we do need to know about these events for Linux FMA and the 'zpool events' interface is new we do post the events. With the addition of the zio_flags field the posted events now contain enough information that a user space consumer can identify and discard these events if it sees fit.

Log I/Os longer than zio_delay_max (30s default) There have been reports of ZFS deadlocking due to what appears to be a lost IO. This patch addes some debugging to determine the exact state of the IO which neither 1) completed, 2) failed, or 3) timed out after zio_delay_max (30) seconds. This information will be logged using the ZFS FMA infrastructure as a 'delay' event and posted to the internal zevent log. By default the last 64 events will be kept in the log but the limit is configurable via the zfs_zevent_len_max module option. To dump the contents of the log use the 'zpool events -v' command and look for the resource.fs.zfs.delay event. It will include various information about the pool, vdev, and zio which may shed some light on the issue. In the context of this change the 120 second kernel blocked thread watchdog has been disabled for synchronous IOs. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #930
