.Sh NAME
.Nm zfs-events
.Nd Events created by the ZFS filesystem
.Sh DESCRIPTION
Description of the different events generated by the ZFS stack.
.Pp
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.
.Pp
To view all events created since the loading of the ZFS infrastructure
(i.e, "the module"), run
.Dl Nm zpool Cm events
to get a short list, and
.Dl Nm zpool Cm events Fl v
to get a full detail of the events and what information
is available about it.
.Pp
This manual page lists the different subclasses that are issued
in the case of an event.
The full event name would be
.Sy ereport.fs.zfs.\& Ns Em SUBCLASS ,
but we only list the last part here.
.
.Sh EVENTS (SUBCLASS)

Issued when there have been data errors in the pool.
.It Sy deadman
Issued when an I/O request is determined to be "hung", this can be caused
by lost completion events due to flaky hardware or drivers.
See

in
.Xr zfs-module-parameters 5
for additional information regarding "hung" I/O detection and configuration.
.It Sy delay
Issued when a completed I/O request exceeds the maximum allowed time
specified by the
.Sy zio_slow_io_ms
module parameter.
This can be an indicator of problems with the underlying storage device.
The number of delay events is ratelimited by the
.Sy zfs_slow_io_events_per_second
module parameter.
.It Sy config

.It Sy zpool
Issued when a pool cannot be imported.
.It Sy zpool.destroy

.It Sy vdev.corrupt_data
Issued when corrupt data have been detected on a vdev.

.It Sy vdev.bad_guid_sum
Issued when a missing device in the pool have been detected.
.It Sy vdev.too_small
Issued when the system (kernel) have removed a device, and ZFS
notices that the device isn't there any more.
This is usually followed by a

event.
.It Sy vdev.bad_label
Issued when the label is OK but invalid.
.It Sy vdev.bad_ashift
Issued when the ashift alignment requirement has increased.

vdev where it have been used to replace a failed drive - only works if
the original drive have been readded).
.It Sy vdev.clear
Issued when clearing device errors in a pool.
Such as running
.Nm zpool Cm clear
on a device in the pool.

.It Sy bad_ranges_min_gap
In order to bound the size of the
.Sy bad_ranges

the bad data.
.It Sy bad_set_bits
If this field exists, it is an array of
.Pq Ar bad data No & ~( Ns Ar good data ) ;
that is, the bits set in the bad data which are cleared in the good data.
Each element corresponds a byte whose offset is in a range in
.Sy bad_ranges ,
and the array is ordered by offset.
Thus, the first element is the first byte in the first
.Sy bad_ranges
range, and the last element is the last byte in the last
.Sy bad_ranges

The first entry counts bits
set in the high-order bit of the first byte, the 9th byte, etc, and the last
entry counts bits set 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.
.It Sy bad_cleared_histogram
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 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.

How many checksum errors that have been detected on the vdev.
.It Sy parent_guid
GUID of the vdev parent.
.It Sy parent_type
Type of parent.
See
.Sy vdev_type .
.It Sy parent_path
Path of the vdev parent (if any).
.It Sy parent_devid
ID of the vdev parent (if any).
.It Sy zio_objset
The object set number for a given I/O request.
.It Sy zio_object
The object number for a given I/O request.
.It Sy zio_level
The indirect level for the block.
Level 0 is the lowest level and includes data blocks.
Values > 0 indicate metadata blocks at the appropriate level.
.It Sy zio_blkid
The block ID for a given I/O request.
.It Sy zio_err
The error number for a failure when handling a given I/O request,
compatible with
.Xr errno 3
with the value of
.Sy EBADE
used to indicate a ZFS checksum error.
.It Sy zio_offset
The offset in bytes of where to write the I/O request for the specified vdev.
.It Sy zio_size
The size in bytes of the I/O request.
.It Sy zio_flags
The current flags describing how the I/O request should be handled.
See the
.Sy I/O FLAGS
section for the full list of I/O flags.
.It Sy zio_stage
The current stage of the I/O in the pipeline.
See the
.Sy I/O STAGES
section for a full list of all the I/O stages.
.It Sy zio_pipeline
The valid pipeline stages for the I/O.
See the
.Sy I/O STAGES
section for a full list of all the I/O stages.
.It Sy zio_delay
The time elapsed (in nanoseconds) waiting for the block layer to complete the
I/O request.
Unlike
.Sy zio_delta ,
this does not include any vdev queuing time and is
therefore solely a measure of the block layer performance.
.It Sy zio_timestamp
The time when a given I/O request was submitted.
.It Sy zio_delta
The time required to service a given I/O request.
.It Sy prev_state
The previous state of the vdev.
.It Sy cksum_expected
The expected checksum value for the block.
.It Sy cksum_actual
The actual checksum value for an errant block.
.It Sy cksum_algorithm
Checksum algorithm used.
See
.Xr zfsprops 7
for more information on the available checksum algorithms.
.It Sy cksum_byteswap
Whether or not the data is byteswapped.
.It Sy bad_ranges
.No [\& Ns Ar start , end )
pairs of corruption offsets.
Offsets are always aligned on a 64-bit boundary,
and can include some gaps of non-corruption.
(See
.Sy bad_ranges_min_gap )
.It Sy bad_ranges_min_gap
In order to bound the size of the
.Sy bad_ranges
array, gaps of non-corruption
less than or equal to
.Sy bad_ranges_min_gap
bytes have been merged with
adjacent corruption.
Always at least 8 bytes, since corruption is detected on a 64-bit word basis.
.It Sy bad_range_sets
This array has one element per range in
.Sy bad_ranges .
Each element contains
the count of bits in that range which were clear in the good data and set
in the bad data.
.It Sy bad_range_clears
This array has one element per range in
.Sy bad_ranges .
Each element contains
the count of bits for that range which were set in the good data and clear in
the bad data.
.It Sy bad_set_bits
If this field exists, it is an array of
.Pq Ar bad data No & ~( Ns Ar good data ) ;
that is, the bits set in the bad data which are cleared in the good data.
Each element corresponds a byte whose offset is in a range in
.Sy bad_ranges ,
and the array is ordered by offset.
Thus, the first element is the first byte in the first
.Sy bad_ranges
range, and the last element is the last byte in the last
.Sy bad_ranges
range.
.It Sy bad_cleared_bits
Like
.Sy bad_set_bits ,
but contains
.Pq Ar good data No & ~( Ns Ar bad data ) ;
that is, the bits set in the good data which are cleared in the bad data.
.It Sy bad_set_histogram
If this field exists, it is an array of counters.
Each entry counts bits set in a particular bit of a big-endian uint64 type.
The first entry counts bits
set in the high-order bit of the first byte, the 9th byte, etc, and the last
entry counts bits set 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.
.It Sy bad_cleared_histogram
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 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.

The individual stages are used to construct these basic I/O
operations: Read, Write, Free, Claim, and Ioctl.
