Currently, additional/extra copies are created for metadata in
addition to the redundancy provided by the pool(mirror/raidz/draid),
due to this 2 times more space is utilized per inode and this decreases
the total number of inodes that can be created in the filesystem. By
setting redundant_metadata to none, no additional copies of metadata
are created, hence can reduce the space consumed by the additional
metadata copies and increase the total number of inodes that can be
created in the filesystem. Additionally, this can improve file create
performance due to the reduced amount of metadata which needs
to be written.

When iterating through children physical ashifts for vdev, prefer
ones above the maximum logical ashift, that we can actually use,
but within the administrator defined maximum.
When selecting top-level vdev ashift, do not set it to the defined
maximum in case physical ashift is even higher, but just ignore one.
Using the maximum does not prevent misaligned writes, but reduces
space efficiency. Since ZFS tries to write data sequentially and
aggregates the writes, in many cases large misanigned writes may be
not as bad as the space penalty otherwise.
Allow internal physical ashifts for vdevs higher than SHIFT_MAX.
May be one day allocator or aggregation could benefit from that.
Reduce zfs_vdev_max_auto_ashift default from 16 (64KB) to 14 (16KB),
so that ZFS may still use bigger ashifts up to SHIFT_MAX (64KB),
but only if it really has to or explicitly told to, but not as an
"optimization".
There are some read-intensive NVMe SSDs that report Preferred Write
Alignment of 64KB, and attempt to build RAIDZ2 of those leads to a
space inefficiency that can't be justified. Instead these changes
make ZFS fall back to logical ashift of 12 (4KB) by default and
only warn user that it may be suboptimal for performance.

Closes#13648Closes#13685
When scrubbing a raidz/draid pool, which contains a replacing or
sparing mirror with multiple online children, only one child will
be read. This is not normally a serious concern because the DTL
records are used to determine where a good copy of the data is.
As long as the data can be read from one child the mirror vdev
will use it to repair gaps in any of its children. Furthermore,
even if the data which was read is corrupt the raidz code will
detect this and issue its own repair I/O to correct the damage
in the mirror vdev.
However, in the scenario where the DTL is wrong due to silent
data corruption (say due to overwriting one child) and the scrub
happens to read from a child with good data, then the other damaged
mirror child will not be detected nor repaired.
While this is possible for both raidz and draid vdevs, it's most
pronounced when using draid. This is because by default the zed
will sequentially rebuild a draid pool to a distributed spare,
and the distributed spare half of the mirror is always preferred
since it delivers better performance. This means the damaged
half of the mirror will go undetected even after scrubbing.
For system administrations this behavior is non-intuitive and in
a worst case scenario could result in the only good copy of the
data being unknowingly detached from the mirror.
This change resolves the issue by reading all replacing/sparing
mirror children when scrubbing. When the BP isn't available for
verification, then compare the data buffers from each child. They
must all be identical, if not there's silent damage and an error
is returned to prompt the top-level vdev to issue a repair I/O to
rewrite the data on all of the mirror children. Since we can't
tell which child was wrong a checksum error is logged against the
replacing or sparing mirror vdev.

When unlinking multiple files from a pool at 100% capacity, it was
possible for ENOSPC to be returned after the first unlink. e.g.
rm -f /mnt/fs/test1.0.0 /mnt/fs/test1.1.0 /mnt/fs/test1.2.0
rm: cannot remove '/mnt/fs/test1.1.0': No space left on device
rm: cannot remove '/mnt/fs/test1.2.0': No space left on device
After waiting for the pending deferred frees from the first unlink to
be processed the remaining files can then be unlinked. This is caused
by the quota limit in dsl_dir_tempreserve_impl() being temporarily
decreased to the allocatable pool capacity less any deferred free
space.

Raw sending from pool1/encrypted with ashift=9 to pool2/encrypted with
ashift=12 results to failure when mounting pool2/encrypted (Input/Output
error). Notably, the opposite, raw sending from a greater ashift to a
lower one does not fail.
This happens because zio_compress_write() falsely checks only
ZIO_FLAG_RAW_COMPRESS and not ZIO_FLAG_RAW_ENCRYPT which is also set in
encrypted raw send streams. In this case it rounds up the psize and if
not equal to the zio->io_size it modifies the block by zeroing out
the extra bytes. Because this happens in a SA attr. registration object
(type=46), the decryption fails upon mounting the filesystem, and zpool
status falsely reports an error.

before deciding whether to zero-pad a block.

for three reasons.
- Exceptions during XSAVE and XRSTOR can only occur if the feature
is not supported or enabled or the memory operand isn't aligned

terribly wrong, and it may be better to stop execution.
- Previously we just printed a warning and didn't handle the fault,

POSIX requires that set-uid and set-gid bits to be removed when an
unprivileged user writes to a file and ZFS does that during normal
operation.
The problem arrises when the write is stored in the ZIL and replayed.
During replay we have no access to original credentials of the process
doing the write, so zfs_write() will be performed with the root
credentials. When root is doing the write set-uid and set-gid bits
are not removed from the file.
To correct that, log a separate TX_SETATTR entry that removed those bits
on first write to such file.
Idea from: Christian Schwarz
Add test for ZIL replay of setuid/setgid clearing.
Improve various edge cases when clearing setid bits:
- The setid bits can be readded during a single write, so make sure to check
for them on every chunk write.
- Log TX_SETATTR record at most once per transaction group (if the setid bits
are keep coming back).
- Move zfs_log_setattr() outside of zp->z_acl_lock.

Instead, we rely on the os_phys flag
OBJSET_FLAG_USERACCOUNTING_COMPLETE to indicate that user accounting is

Issue #11300
Verify that all empty sectors are zero filled before using them to
calculate parity. Failure to do so can result in incorrect parity
columns being generated and written to disk if the contents of an
empty sector are non-zero. This was possible because the checksum
only protects the data portions of the buffer, not the empty sector
padding.
This issue has been addressed by updating raidz_parity_verify() to
check that all dRAID empty sectors are zero filled. Any sectors
which are non-zero will be fixed, repair IO issued, and a checksum
error logged. They can then be safely used to verify the parity.
This specific type of damage is unlikely to occur since it requires
a disk to have silently returned bad data, for an empty sector, while
performing a scrub. However, if a pool were to have been damaged
in this way, scrubbing the pool with this change applied will repair
both the empty sector and parity columns as long as the data checksum
is valid. Checksum errors will be reported in the `zpool status`
output for any repairs which are made.

The import_rewind_device_replaced.ksh test was never entirely reliable
because it depends on MOS data not being overwritten. The MOS data is
not protected by the snapshot so occasional failures were always
expected. However, this test is now failing reliably on all platforms
indicating something has changed in the code since the test was marked
"maybe". Convert the test to a "known" failure until the root cause
is identified and resolved.

Due to a possible lock inversion the zvol open call path on Linux
needs to be able to retry in the case where the spa_namespace_lock
cannot be acquired.
For Linux 5.12 an older kernel this was accomplished by returning
-ERESTARTSYS from zvol_open() to request that blkdev_get() drop
the bdev->bd_mutex lock, reaquire it, then call the open callback
again. However, as of the 5.13 kernel this behavior was removed.
Therefore, for 5.12 and older kernels we preserved the existing
retry logic, but for 5.13 and newer kernels we retry internally in
zvol_open(). This should always succeed except in the case where
a pool's vdev are layed on zvols, in which case it may fail. To
handle this case vdev_disk_open() has been updated to retry when
opening a device when -ERESTARTSYS is returned.

With the addition of functionality to rerun failing tests, some
tests that fail only sometimes still fail often enough to degrade
the reliability of the sanity runs. Remove them from the runfile
until they reliably pass.
