zfs\-events \- Events created by the ZFS filesystem.
.SH DESCRIPTION
.sp
.LP
Description of the different events generated by the ZFS stack.
.sp
Most of these don't have any description. The events generated by ZFS
have never been publicly documented. What is here is intended as a
starting point to provide documentation for all possible events.
.sp
To view all events created since the loading of the ZFS infrastructure
(i.e, "the module"), run
.P
.nf
\fBzpool events\fR
.fi
.P
to get a short list, and
.P
.nf
\fBzpool events -v\fR
.fi
.P
to get a full detail of the events and what information
is available about it.
.sp
This man page lists the different subclasses that are issued
in the case of an event. The full event name would be
\fIereport.fs.zfs.SUBCLASS\fR, but we only list the last
part here.

Extend deadman logic The intent of this patch is extend the existing deadman code such that it's flexible enough to be used by both ztest and on production systems. The proposed changes include: * Added a new `zfs_deadman_failmode` module option which is used to dynamically control the behavior of the deadman. It's loosely modeled after, but independant from, the pool failmode property. It can be set to wait, continue, or panic. * wait - Wait for the "hung" I/O (default) * continue - Attempt to recover from a "hung" I/O * panic - Panic the system * Added a new `zfs_deadman_ziotime_ms` module option which is analogous to `zfs_deadman_synctime_ms` except instead of applying to a pool TXG sync it applies to zio_wait(). A default value of 300s is used to define a "hung" zio. * The ztest deadman thread has been re-enabled by default, aligned with the upstream OpenZFS code, and then extended to terminate the process when it takes significantly longer to complete than expected. * The -G option was added to ztest to print the internal debug log when a fatal error is encountered. This same option was previously added to zdb in commit fa603f82. Update zloop.sh to unconditionally pass -G to obtain additional debugging. * The FM_EREPORT_ZFS_DELAY event which was previously posted when the deadman detect a "hung" pool has been replaced by a new dedicated FM_EREPORT_ZFS_DEADMAN event. * The proposed recovery logic attempts to restart a "hung" zio by calling zio_interrupt() on any outstanding leaf zios. We may want to further restrict this to zios in either the ZIO_STAGE_VDEV_IO_START or ZIO_STAGE_VDEV_IO_DONE stages. Calling zio_interrupt() is expected to only be useful for cases when an IO has been submitted to the physical device but for some reasonable the completion callback hasn't been called by the lower layers. This shouldn't be possible but has been observed and may be caused by kernel/driver bugs. * The 'zfs_deadman_synctime_ms' default value was reduced from 1000s to 600s. * Depending on how ztest fails there may be no cache file to move. This should not be considered fatal, collect the logs which are available and carry on. * Add deadman test cases for spa_deadman() and zio_wait(). * Increase default zfs_deadman_checktime_ms to 60s.

If this field exists, it is an array of counters. Each entry counts bit clears
in a particular bit of a big-endian uint64 type. The first entry counts bits
clears of the the high-order bit of the first byte, the 9th byte, etc, and the
last entry counts clears of the low-order bit of the 8th byte, the 16th byte,
etc. This information is useful for observing a stuck bit in a parallel data
path, such as IDE or parallel SCSI.
Initial attempt to document events and payloads. In no way complete - most have been trial and error and some deducing what they could mean. It needs more information from someone that knows the code better. But this is a start and it lays the basic structure for adding this additional detail.

The ZFS I/O pipeline is comprised of various stages which are defined
below. The individual stages are used to construct these basic I/O
operations: Read, Write, Free, Claim, and Ioctl. These stages may be
set on an event to describe the life cycle of a given I/O.
