df55ba7c49 Detect a slow raidz child during reads
A single slow responding disk can affect the overall read
performance of a raidz group.  When a raidz child disk is
determined to be a persistent slow outlier, then have it
sit out during reads for a period of time. The raidz group
can use parity to reconstruct the data that was skipped.

Each time a slow disk is placed into a sit out period, its
`vdev_stat.vs_slow_ios count` is incremented and a zevent
class `ereport.fs.zfs.delay` is posted.

The length of the sit out period can be changed using the
`raid_read_sit_out_secs` module parameter.  Setting it to
zero disables slow outlier detection.

123bfc32f3 ZTS: Print warning if running ZTS user_run test locally
Print a warning if you're attempting to run a ZTS test that calls
'user_run', and the ephemeral user doesn't have permissions to
access the test binaries.

This can happen if you're running ZTS from a local git repo.  In
that case the test user (say, 'testuser1') may need access to the
ZTS binaries in:

/home/<your_username>/zfs/tests/zfs-tests/bin/

... but 'testuser1' doesn't have permission to enter your home dir:

/home/<your_username>

The warning will help alert users to what is going on.  This will
not be an issue when ZTS is actually installed on the system
(via 'make install' or from packages).

26983d6fa7 Add allocation profile export and zhack subcommand for import
When attempting to debug performance problems on large systems, one of
the major factors that affect performance is free space
fragmentation. This heavily affects the allocation process, which is an
area of active development in ZFS. Unfortunately, fragmenting a large
pool for testing purposes is time consuming; it usually involves filling
the pool and then repeatedly overwriting data until the free space
becomes fragmented, which can take many hours. And even if the time is
available, artificial workloads rarely generate the same fragmentation
patterns as the natural workloads they're attempting to mimic.

This patch has two parts. First, in zdb, we add the ability to export
the full allocation map of the pool. It iterates over each vdev,
printing every allocated segment in the ms_allocatable range tree. This
can be done while the pool is online, though in that case the allocation
map may actually be from several different TXGs as new ones are loaded
on demand.

The second is a new subcommand for zhack, zhack metaslab leak (and its
supporting kernel changes). This is a zhack subcommand that imports a
pool and then modified the range trees of the metaslabs, allowing the
sync process to write them out normall. It does not currently store
those allocations anywhere to make them reversible, and there is no
corresponding free subcommand (which would be extremely dangerous); this
is an irreversible process, only intended for performance testing. The
only way to reclaim the space afterwards is to destroy the pool or roll
back to a checkpoint.

87e35bd3ab ZTS: Fix fault_limits timeouts
fault_limits would often hit the 10min timeout and be killed on Fedora
41-42.  Investigation showed that the 'fill_fs' portion of the test,
which would fill the pool with junk data before vdev replacement, was
writing highly compressible data (~126x), which would have taxed the
CPUs, potentially causing the timeout.

The fix is to write random data and reduce the number of writes.
This has an added benefit that more real data being is written to the
pool (~1GB) vs the old way (~300-400MB).  It also speeds up the test.

1f8c39ddb2 ZTS: test response of various sync methods under different failmodes
These are all the same shape: set up the pool to suspend on first write,
then perform some write+sync operation. The pool should suspend, and the
sync operation should respond according to the failmode= property.

We test fsync(), msync() and two forms of write() (open with O_SYNC, and
async with sync=always), which all take slightly different paths to
zil_commit() and back.

A helper function is included to do the write+sync sequence with mmap()
and msync(), since I didn't find a convenient tool to do that.

Since this begins to use new "rewrite" flag in the block pointers,
this commit introduces a new read-compatible per-dataset feature

it is activated on first use and deactivated on deletion of the

48c9b2e79d ZTS: include microsecond timestamps on all output
When reviewing test output after a failure, it's often quite difficult
to work out the order and timing of events, and to correlate test suite
output with kernel logs.

This adds timestamps to ZTS output to help with this, in three places:

- all of the standard log_XXX functions ultimately end up in _printline,
  which now prefixes output with a timestamp. An escape hatch
  environment variable is provided for user_cmd, which often calls the
  logging functions while also depending on the captured output.

- the test runner logging function log() also now prefixes its output
  with a timestamp.

- on failure, when capturing the kernel log in zfs_dmesg.ksh, the "iso"
  time format is requested.

BRT: Fix ZAP entry endianness
During original block cloning implementation a mistake was made,
making BRT ZAP entries an array of 8 1-byte entries instead of 1
entry of 8 bytes. This makes the pools non-endian-safe.

This commit introduces a new read-compatible pool feature
"com.truenas:block_cloning_endian", fixing the endianness issue
for new pools while maintaining compatibility with existing ones.

The feature is automatically activated when creating the first BRT
ZAP (ensuring we don't activate it on pools that already have BRT
entries in the old format).  When active, BRT entries are stored
as single 8-byte values.

Relax special_small_blocks restrictions
special_small_blocks is applied to blocks after compression, so it
makes no sense to demand its values to be power of 2.  At most
they could be multiple of 512, but that would still buy us nothing,
so lets allow them be any within SPA_MAXBLOCKSIZE.

Also special_small_blocks does not really need to depend on the
set recordsize, enabled pool features or presence of special vdev.
At worst in any of those cases it will just do nothing, so we
should not complicate users lives by artificial limitations.

While there, polish comments for recordsize and volblocksize.

Release topology restrictions on special/dedup
Special vdevs were originally designed as a small blocks storage
for dRAID, for which role RAIDZ/dRAID topologies are not good.
But it is more often used as SSD storage for metadata and hot
data of HDD pools.  In these use cases narrow RAIDZ of SSDs might
be fine, so we should not introduce unnecessary restrictions,
and ZFS internally does not care.

Similar applies to dedup vdevs.  Original DDT used 4KB blocks,
for which anything but mirror was a terrible storage.  But new
FDT implementation uses 32KB blocks by default, which are much
less demanding even including compression, and which could be
increased even higher now, if needed.

FreeBSD: Add posix_fadvise(POSIX_FADV_WILLNEED) support
As commit 320f0c6 did for Linux, connect POSIX_FADV_WILLNEED
up to dmu_prefetch() on FreeBSD.

While there, fix portability problems in tests/functional/fadvise.

1.  Instead of relying on the numerical values of POSIX_FADV_XXX macros,
    accept macro names as arguments to the file_fadvise program.  (The
    numbers happen to match on Linux and FreeBSD, but future systems may
    vary and it seems a little strange/raw to count on that.)

2.  For implementation reasons, SEQUENTIAL doesn't reach ZFS via FreeBSD
    VFS currently (perhaps something that should be investigated in
    FreeBSD).  Since on Linux we're treating SEQUENTIAL and WILLNEED the
    same, it doesn't really matter which one we use, so switch the test
    over to WILLNEED exercise the new prefetch code on both OSes the
    same way.

Wire O_DIRECT also to Uncached I/O (#17218)
Before Direct I/O was implemented, I've implemented lighter version
I called Uncached I/O.  It uses normal DMU/ARC data path with some
optimizations, but evicts data from caches as soon as possible and
reasonable.  Originally I wired it only to a primarycache property,
but now completing the integration all the way up to the VFS.

While Direct I/O has the lowest possible memory bandwidth usage,
it also has a significant number of limitations.  It require I/Os
to be page aligned, does not allow speculative prefetch, etc.  The
Uncached I/O does not have those limitations, but instead require
additional memory copy, though still one less than regular cached
I/O.  As such it should fill the gap in between.  Considering this
I've disabled annoying EINVAL errors on misaligned requests, adding
a tunable for those who wants to test their applications.

To pass the information between the layers I had to change a number
of APIs.  But as side effect upper layers can now control not only
the caching, but also speculative prefetch.  I haven't wired it to
VFS yet, since it require looking on some OS specifics.  But while
there I've implemented speculative prefetch of indirect blocks for
Direct I/O, controllable via all the same mechanisms.

Introduce zfs rewrite subcommand (#17246)
This allows to rewrite content of specified file(s) as-is without
modifications, but at a different location, compression, checksum,
dedup, copies and other parameter values.  It is faster than read
plus write, since it does not require data copying to user-space.
It is also faster for sync=always datasets, since without data
modification it does not require ZIL writing.  Also since it is
protected by normal range range locks, it can be done under any
other load.  Also it does not affect file's modification time or
other properties.

test-runner: rework output dir construction
The old code would compare all the test group names to work out some
sort of common path, but it didn't appear to work consistently,
sometimes placing output in a top-level dir, other times in one or more
subdirs. (I confess, I do not quite understand what it's supposed to
do).

This is a very simple rework that simply looks at all the test group
paths, removes common leading components, and uses the remainder as the
output directory. This should work because groups paths are unique, and
means we get a output dir tree of roughly the same shape as the test
groups in the runfiles and the test source dirs themselves.

Make zvol I/O requests processing asynchronous on FreeBSD side in some
cases. Clone zvol threading logic and required module parameters from
Linux side. Make zvol threadpool creation/destruction logic shared for
both Linux and FreeBSD.
The IO requests are processed asynchronously in next cases:
- volmode=geom: if IO request thread is geom thread or cannot sleep.
- volmode=cdev: if IO request passed thru struct cdevsw .d_strategy
routine, mean is AIO request.
In all other cases the IO requests are processed synchronously. The
volthreading zvol property is ignored on FreeBSD side.

Implement allocation size ranges and use for gang leaves (#17111)
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.
