Slow disk response times can be indicative of a failing drive. ZFS
currently tracks slow I/Os (slower than zio_slow_io_ms) and generates

like is done for checksum or I/O errors. This change adds slow disk
diagnosis to ZED which is opt-in using new VDEV properties:
VDEV_PROP_SLOW_IO_N
VDEV_PROP_SLOW_IO_T

Entries in the dbuf cache contribute only the size of the dbuf data to
the cache size. Attached "user" data is not counted. This can lead to
the data currently "owned" by the cache consuming more memory accounting
appears to show. In some cases (eg a metadnode data block with all child
dnode_t slots allocated), the actual size can be as much as 3x as what
the cache believes it to be.
This is arguably correct behaviour, as the cache is only tracking the
size of the dbuf data, not even the overhead of the dbuf_t. On the other
hand, in the above case of dnodes, evicting cached metadnode dbufs is
the only current way to reclaim the dnode objects, and can lead to the
situation where the dbuf cache appears to be comfortably within its
target memory window and yet is holding enormous amounts of slab memory
that cannot be reclaimed.
This commit adds a facility for a dbuf user to artificially inflate the
apparent size of the dbuf for caching purposes. This at least allows for
cache tuning to be adjusted to match something closer to the real memory
overhead.
metadnode dbufs carry a >1KiB allocation per dnode in their user data.
This informs the dbuf cache machinery of that fact, allowing it to make
better decisions when evicting dbufs.

This feature allows disks to be added one at a time to a RAID-Z group,
expanding its capacity incrementally. This feature is especially useful
for small pools (typically with only one RAID-Z group), where there
isn't sufficient hardware to add capacity by adding a whole new RAID-Z
group (typically doubling the number of disks).
== Initiating expansion ==
A new device (disk) can be attached to an existing RAIDZ vdev, by
running `zpool attach POOL raidzP-N NEW_DEVICE`, e.g. `zpool attach tank
raidz2-0 sda`. The new device will become part of the RAIDZ group. A
"raidz expansion" will be initiated, and the new device will contribute
additional space to the RAIDZ group once the expansion completes.
The `feature@raidz_expansion` on-disk feature flag must be `enabled` to
initiate an expansion, and it remains `active` for the life of the pool.
In other words, pools with expanded RAIDZ vdevs can not be imported by
older releases of the ZFS software.
== During expansion ==
The expansion entails reading all allocated space from existing disks in
the RAIDZ group, and rewriting it to the new disks in the RAIDZ group
(including the newly added device).
The expansion progress can be monitored with `zpool status`.
Data redundancy is maintained during (and after) the expansion. If a
disk fails while the expansion is in progress, the expansion pauses
until the health of the RAIDZ vdev is restored (e.g. by replacing the
failed disk and waiting for reconstruction to complete).
The pool remains accessible during expansion. Following a reboot or
export/import, the expansion resumes where it left off.
== After expansion ==
When the expansion completes, the additional space is available for use,
and is reflected in the `available` zfs property (as seen in `zfs list`,
`df`, etc).
Expansion does not change the number of failures that can be tolerated
without data loss (e.g. a RAIDZ2 is still a RAIDZ2 even after
expansion).
A RAIDZ vdev can be expanded multiple times.
After the expansion completes, old blocks remain with their old
data-to-parity ratio (e.g. 5-wide RAIDZ2, has 3 data to 2 parity), but
distributed among the larger set of disks. New blocks will be written
with the new data-to-parity ratio (e.g. a 5-wide RAIDZ2 which has been
expanded once to 6-wide, has 4 data to 2 parity). However, the RAIDZ
vdev's "assumed parity ratio" does not change, so slightly less space
than is expected may be reported for newly-written blocks, according to
`zfs list`, `df`, `ls -s`, and similar tools.

The change is simple -- restore the original code so that the VDEV

was to devise a second ZTS test, that would test auto-replace for

With that new test, we can now do an A|B test with , and without,
the fix to confirm that auto-replace for by-id paths works. The
existing auto-replace test, functional/fault/auto_replace_001_pos,
will confirm that we didn't break auto-replace for 'by-vdev' paths.
In the original functional/fault/auto_replace_001_pos test, the disk
wipe (using dd) was not effective in removing the partitioning since
the kernel was never informed of the wipe.
Added a call to wipefs(8) so that the kernel is informed and ZED will
re-partition the device.
Added a validation step that the re-partitioning occurred by
confirming that the GPT partition UUID changes.

Previously, if a cachefile is passed to zpool import, the cached config
is mostly offered as-is to ZFS_IOC_POOL_TRYIMPORT->spa_tryimport(), and
the results are taken as the canonical pool config and handed back to
ZFS_IOC_POOL_IMPORT.
In the course of its operation, spa_load() will inspect the pool and
build a new config from what it finds on disk. However, it then
regenerates a new config ready to import, and so rightly sets the hostid
and hostname for the local host in the config it returns.
Because of this, the "require force" checks always decide the pool is
exported and last touched by the local host, even if this is not true,
which is possible in a HA environment when MMP is not enabled. The pool
may be imported on another head, but the import checks still pass here,
so the pool ends up imported on both.
(This doesn't happen when a cachefile isn't used, because the pool
config is discovered in userspace in zpool_find_import(), and that does
find the on-disk hostid and hostname correctly).
Since the systemd zfs-import-cache.service unit uses cachefile imports,
this can lead to a system returning after a crash with a "valid"
cachefile on disk and automatically, quietly, importing a pool that has
already been taken up by a secondary head.
This commit causes the on-disk hostid and hostname to be included in the
ZPOOL_CONFIG_LOAD_INFO item in the returned config, and then changes the
"force" checks for zpool import to use them if present.
This method should give no change in behaviour for old userspace on new
kernels (they won't know to look for the new config items) and for new
userspace on old kernels (the won't find the new config items).

can be subject to ztest's error injection.
The other ways to fix this would be to change the error injection to
not trigger on removals (which may not be technically feasible), or
to change the import code to not report configurations that are so
short on devices (which would potentially have unpleasant end-user
effects when trying to recover from data losses/device configuration
issues).

Have libzfs call a special `zfs_prepare_disk` script before a disk is
included into the pool. The user can edit this script to add things
like a disk firmware update or a disk health check. Use of the script
is totally optional. See the zfs_prepare_disk manpage for full details.

For sharesmb and sharenfs properties, the status of setting the
property is tied with whether we succeed to share the dataset or
not. In case sharing the dataset is not successful, this is
treated as overall failure of setting the property. In this case,
if we check the property after the failure, it is set to on.
This commit updates this behavior and the status of setting the
share properties is not returned as failure, when we fail to
share the dataset.
For sharenfs property, if access list is provided, the syntax
errors in access list/host adresses are not validated until after
setting the property during postfix phase while trying to
share the dataset. This is not correct, since the property has
already been set when we reach there.
Syntax errors in access list/host addresses are validated while
validating the property list, before setting the property and
failure is returned to user in this case when there are errors
in access list.

There are some inconsistencies in the handling of mountpoint
property. This commit updates the behavior and makes it
consistent.
If mountpoint property is set when dataset is unmounted, this
would update the mountpoint property. The mountpoint could be
valid or invalid in this case. Setting the mountpoint property
would result in success in this case. Dataset would still be
unmounted here.
On the other hand, if dataset is mounted and mountpoint
property is updated to something invalid where mount cannot be
successful, for example, setting the mountpoint inside a readonly
directory. This would unmount the dataset, set the mountpoint
property to requested value and tries to mount the dataset. The
mount operation returns error and this error is treated as
overall failure of setting the property while the property is
actually set.
To make the behavior consistent in case dataset is mounted or
unmounted, we should try to mount the dataset whenever mountpoint
property is updated. This would result in mounting the datasets
if canmount property is set to on, regardless if the dataset was
previously unmounted.
The failure in mount operation while setting the mountpoint
property should not be treated as failure, since the property is
actually set now to user requested value.

'program help subcommand' is a reasonably common pattern for
multifunction command-line programs. This commit adds support for that
style to the zpool and zfs commands.
When run as 'zpool help [<topic>]' or 'zfs help [<topic>]', executes the
'man' program on the PATH with the most likely manpage name for the
requested topic: "zpool-<topic>" or "zfs-<topic>" for subcommands, or
"zpool<topic>" or "zfs<topic>" for the "concepts" and "props" topics.
If no topic is supplied, uses the top "zpool" or "zfs" pages.

For zpool import and zpool split, zpool_enable_datasets is called
to mount and share all datasets in a pool. If there is an error
while mounting or sharing any dataset in the pool, the status of
import or split is reported as failure. However, the changes do
show up in zpool list.
This commit updates the error reporting in zpool import and zpool
split path. More descriptive messages are shown to user in case
there is an error during mount or share. Errors in mount or share
do not effect the overall status of zpool import and zpool split.

Currently redaction bookmarks and their associated redaction lists
have a relatively low limit of 36 redaction snapshots. This is imposed
by the number of snapshot GUIDs that fit in the bonus buffer of the
redaction list object. While this is more than enough for most use
cases, there are some limited cases where larger numbers would be
useful to support.
We tweak the redaction list creation code to use a spill block if
the number of redaction snapshots is above the amount that would fit
in the bonus buffer. We also make a small change to allow spill blocks
to be use for types of data besides SA. In order to fully leverage
this logic, we also change the redaction code to use vmem_alloc, to
handle extremely large allocations if needed. Finally, small tweaks
were made to the zfs commands and the test suite.
