When devices are missing or claimed by another subsystem (e.g.
mdadm, LVM), zpool import reports "The pool metadata is corrupted"
and suggests destroying the pool. This is misleading because the
metadata is not necessarily corrupted -- it may simply be incomplete
due to inaccessible devices.
Update the status, action, and recovery messages to acknowledge
that missing devices can trigger this status, and suggest checking
device availability before resorting to pool destruction.

As part of SPA_LOAD_IMPORT add an additional activity check to
detect simultaneous imports from different hosts. This check is
only required when the timing is such that there's no activity
for the the read-only tryimport check to detect. This extra
safety chceck operates as follows:
1. Repeats the following MMP check 10 times:
a. Write out an MMP uberblock with the best txg and a random
sequence id to all primary pool vdevs.
b. Verify a minimum number of good writes such that even if
the pool appears degraded on the remote host it will see
at least one of the updated MMP uberblocks.
c. Wait for the MMP interval this leaves a window for other
racing hosts to make similar modifications which can be
detected.
d. Call vdev_uberblock_load() to determine the best uberblock
to use, this should be the MMP uberblock just written.
e. Verify the txg and random sequeunce number match the MMP
uberblock written in 1a.
2. Restore the original MMP uberblocks. This allows the check
to be performed again if the pool fails to import for an
unrelated reason.
This change also includes some refactoring and minor improvements.
- Never try loading earlier txgs during import when the import
fails with EREMOTEIO or EINTER. These errors don't indicate
the txg is damaged but instead that its either in use on a
remote host or the import was interactively cancelled. No
rewind is also performed for EBADD which can result from a
stale trusted config when doing a verbatim import.
- Refactor the code for consistent logging of the multihost
activity check using spa_load_note() and console messages
indicating when the activity check was trigger and the result.
- Added MMP_*_MASK and MMP_SEQ_CLEAR() macros to allow easier
modification of the sequence number in an uberblock.
- Added ZFS_LOAD_INFO_DEBUG environment variable which can be
set to log to dump to stdout the spa_load_info nvlist returned
during import. This is used by the updated mmp test cases
to determine if an activity check was run and its result.
- Standardize the mmp messages similarly to make it easier to
find all the relevent mmp lines in the debug log.

A deadlock occurs when snapshot expiry tasks are cancelled while holding
locks. The snapshot expiry task (snapentry_expire) spawns an umount
process and waits for it to complete. Concurrently, ARC memory pressure
triggers arc_prune which calls zfs_exit_fs(), attempting to cancel the
expiry task while holding locks. The umount process spawned by the
expiry task blocks trying to acquire locks held by arc_prune, which is
blocked waiting for the expiry task to complete. This creates a circular
dependency: expiry task waits for umount, umount waits for arc_prune,
arc_prune waits for expiry task.
Fix by adding non-blocking cancellation support to taskq_cancel_id().
The zfs_exit_fs() path calls zfsctl_snapshot_unmount_delay() to
reschedule the unmount, which needs to cancel any existing expiry task.
It now uses non-blocking cancellation to avoid waiting while holding
locks, breaking the deadlock by returning immediately when the task is
already running.
The per-entry se_taskqid_lock has been removed, with all taskqid
operations now protected by the global zfs_snapshot_lock held as
WRITER. Additionally, an se_in_umount flag prevents recursive waits when
zfsctl_destroy() is called during unmount. The taskqid is now only
cleared by the caller on successful cancellation; running tasks clear
their own taskqid upon completion.

We have infinite loop and on certain condition, we exit this loop

The problem is that modern compilers are able to recognize that we

it is dead code there.
I think, instead of pthread_exit(), it is better to break out of loop
and let the last statements to work as intended. This is because
we do need to keep pthread_cleanup_pop() anyhow. Of course,
it is matter of taste if we want to use return or pthread_exit as very

In "all pools" mode, pool_iter_refresh() will call zpool_iter(), which

have the pool, this is a different handle, so we just release it and
return. Back in pool_iter_refresh(), we then call zpool_stats_refresh()
again for our handle on the same pool.
All together, this means we're doing two ZFS_IOC_POOL_STATS calls into
the kernel for every pool in the system. This isn't wrong, but it does
double the pressure on global locks.
Instead, we add a new function zpool_refresh_stats_from_handle() that
simply copies the pool config and state from one handle to another, and
use it to update our handle before we release it in add_pool(), so we
only have one call per pool per interval.

Currently, commands that resume a scrub/errorscrub from a paused state
don't get logged in the pool history. This is because resumes actually
return ECANCELED, instead of 0. This causes the tsd code in the common
ioctl logic to not think the ioctl succeeded, which causes the
log_history ioctl to fail with EPERM. However, for resuming a scrub from
a paused state, ECANCELED is success.
There are two options for how to deal with this. The first is the one
that I implemented here; I can't find a good reason for dmu_scan to
return ECANCELED on resume instead of 0, so let's just not. The only
place we check for the ECANCELED value is in zpool_scan, where we just
convert it back to zero. However, I am aware that this is changing an
ioctl interface, which I believe is a breaking change. I don't think
it's an important change, but maybe there is someone who relies on it.
The other option that could be implemented is to either allow ECANCELED
specifically from dsl_scan in the common ioctl code, or add a generic
facility to the common ioctl code that allows each command to specify
whether or not success happened, regardless of the return values. I am
open to feedback on which option people think would be better.

When forced to resort to ganging, ZFS currently allocates three child
blocks, each one third of the size of the original. This is true
regardless of whether larger allocations could be made, which would
allow us to have fewer gang leaves. This improves performance when
fragmentation is high enough to require ganging, but not so high that
all the free ranges are only just big enough to hold a third of the
recordsize. This is also useful for improving the behavior of a future
change to allow larger gang headers.
We add the ability for the allocation codepath to allocate a range of
sizes instead of a single fixed size. We then use this to pre-allocate
the DVAs for the gang children. If those allocations fail, we fall back
to the normal write path, which will likely re-gang.
