Currently, wait_scrubbed() is the only function of its kind that
accepts a timeout, which is 10s by default. This timeout is pretty
short for a scrub and causes test failures if we run too long. This
patch removes the timeout, instead leaning on the global test suite
timeout to ensure the tests keep moving.

Closes#8195
As a result of the changes made in 8585, it's possible for an excessive
amount of vdev flush commands to be issued under some workloads.
Specifically, when the workload consists of mostly async write activity,
interspersed with some sync write and/or fsync activity, we can end up
issuing more flush commands to the underlying storage than is actually
necessary. As a result of these flush commands, the write latency and
overall throughput of the pool can be poorly impacted (latency
increases, throughput decreases).
Currently, any time an lwb completes, the vdev(s) written to as a result
of that lwb will be issued a flush command. The intenion is so the data
written to that vdev is on stable storage, prior to communicating to any
waiting threads that their data is safe on disk.
The problem with this scheme, is that sometimes an lwb will not have any
threads waiting for it to complete. This can occur when there's async
activity that gets "converted" to sync requests, as a result of calling
the zil_async_to_sync() function via zil_commit_impl(). When this
occurs, the current code may issue many lwbs that don't have waiters
associated with them, resulting in many flush commands, potentially to
the same vdev(s).
For example, given a pool with a single vdev, and a single fsync() call
that results in 10 lwbs being written out (e.g. due to other async
writes), that will result in 10 flush commands to that single vdev (a
flush issued after each lwb write completes). Ideally, we'd only issue a
single flush command to that vdev, after all 10 lwb writes completed.
Further, and most important as it pertains to this change, since the
flush commands are often very impactful to the performance of the pool's
underlying storage, unnecessarily issuing these flush commands can
poorly impact the performance of the lwb writes themselves. Thus, we
need to avoid issuing flush commands when possible, in order to acheive
the best possible performance out of the pool's underlying storage.
This change attempts to address this problem by changing the ZIL's logic
to only issue a vdev flush command when it detects an lwb that has a
thread waiting for it to complete. When an lwb does not have threads
waiting for it, the responsibility of issuing the flush command to the
vdevs involved with that lwb's write is passed on to the "next" lwb.
It's only once a write for an lwb with waiters completes, do we issue
the vdev flush command(s). As a result, now when we issue the flush(s),
we will issue them to the vdevs involved with that specific lwb's write,
but potentially also to vdevs involved with "previous" lwb writes (i.e.
if the previous lwbs did not have waiters associated with them).
Thus, in our prior example with 10 lwbs, it's only once the last lwb
completes (which will be the lwb containing the waiter for the thread
that called fsync) will we issue the vdev flush command; all of the
other lwbs will find they have no waiters, so they'll pass the
responsibility of the flush to the "next" lwb (until reaching the last
lwb that has the waiter).

* Detect IO errors during device removal
While device removal cannot verify the checksums of individual
blocks during device removal, it can reasonably detect hard IO
errors from the leaf vdevs. Failure to perform this error
checking can result in device removal completing successfully,
but moving no data which will permanently corrupt the pool.
Situation 1: faulted/degraded vdevs
In the configuration shown below, the removal of mirror-0 will
permanently corrupt the pool. Device removal will preferentially
copy data from 'vdev1 -> vdev3' and from 'vdev2 -> vdev4'. Which
in this case will result in nothing being copied since one vdev
in each of those groups in unavailable. However, device removal
will complete successfully since all IO errors are ignored.
tank DEGRADED 0 0 0
mirror-0 DEGRADED 0 0 0
/var/tmp/vdev1 FAULTED 0 0 0 external fault
/var/tmp/vdev2 ONLINE 0 0 0
mirror-1 DEGRADED 0 0 0
/var/tmp/vdev3 ONLINE 0 0 0
/var/tmp/vdev4 FAULTED 0 0 0 external fault
This issue is resolved by updating the source child selection
logic to exclude unreadable leaf vdevs. Additionally, unwritable
destination child vdevs which can never succeed are skipped to
prevent generating a large number of write IO errors.
Situation 2: individual hard IO errors
During removal if an unexpected hard IO error is encountered when
either reading or writing the child vdev the entire removal
operation is cancelled. While it may be possible to reconstruct
the data after removal that cannot be guaranteed. The only
strictly safe thing to do is to cancel the removal.
As a future improvement we may want to instead suspend the removal
process and allow the damaged region to be retried. But that work
is left for another time, hard IO errors during the removal process
are expected to be exceptionally rare.

Issue #6900Closes#8161
ztest currently uses the boolean flag ztest_device_removal_active
to protect some tests that may not run successfully if they occur
at the same time as ztest_device_removal(). Unfortunately, in the
event that ztest is in the middle of a device removal when it
decides to issue a SIGKILL, the device removal will be
automatically restarted (without setting the flag) when the pool
is re-imported on the next run. This patch corrects this by
ensuring that any in-progress removals are completed before running
further tests after the re-import.
This patch also makes a few small changes to prevent race conditions
involving the creation and destruction of spa->spa_vdev_removal,
since this field is not protected by any locks. Some checks that
may run concurrently with setting / unsetting this field have been
updated to check spa->spa_removing_phys.sr_state instead. The most
significant change here is that spa_removal_get_stats() no longer
accounts for in-flight work done, since that could result in a NULL
pointer dereference.

for this is that these tests use a combination of zinject and

to verify their test commands. This method works most of the time,
but provides no guarantees and leads to flaky behavior. This patch

scans make no progress, guaranteeing that tests can be run without
racing.
This patch also changes zfs_remove_max_bytes_pause to match this

OpenZFS-issue: https://www.illumos.org/issues/8115
OpenZFS-commit: https://github.com/openzfs/openzfs/commit/a3f0e2b569Closes#8092
PR #8114 quoted the ${ENCRYPTIONROOT} parameter to ensure we don't
lose spaces when unlocking root filesystem in the off chance that
it has a space in its name.
Unfortunately, dracut and initramfs-tools do not actually get the
quotes from the cmdline. If we use root=ZFS="root pool/filesystem
name" the script still only sees root=ZFS=root and no quotation
marks.
Because + is a reserved character in ZFS, it's used as a
placeholder for spaces in the kernel cmdline. In this way,
root=ZFS=root+pool/filesystem+name will properly expand by
replacing the character with sed (POSIX compliant method).

Ensure that the _unitdir, _presetdir, _modulesloaddir, and
_systemdgeneratordir macros are always defined. If not set
them to the expected default values. Pass all of these options
to ./configure and package the resulting files in those locations.
Additionally, set __brp_mangle_shebangs_exclude_from until the
conversion to Python 3 is complete so they may be built cleanly
under mock.

This commit adds a new test case to the ZFS Test Suite to verify ZED
can detect when a device is physically removed from a running system:
the device will be offlined if a spare is not available in the pool.
We implement this by using the existing libudev functionality and
without relying solely on the FM kernel module capabilities which have
been observed to be unreliable with some kernels.

complete in zio_slow_io_ms milliseconds. It also adds a new parsable

zfs_rename_006_pos has been flaky in the past because it was
missing a call to block_device_wait to ensure the zvols it creates
are present before running dd. Whenever this this happened,
zfs_rename_009_neg would also fail because the first test would
leak a zvol clone that it did not know how to clean up. This patch
fixes the root cause and reenables the test. It also fixes some
minor grammar errors.
