During scans (scrubs or resilvers), it sorts the blocks in each transaction
group by block offset; the result can be a significant improvement. (On my
test system just now, which I put some effort to introduce fragmentation into
the pool since I set it up yesterday, a scrub went from 1h2m to 33.5m with the
changes.) I've seen similar rations on production systems.

import in its form with an old name and a new name. This allows to
import (or create) a pool under a name that's different from its real,
permanent name without affecting that name. This is useful when working
with VM images or images of other physical systems if they happen to
have a ZFS pool with the same name as the host system.

9235 rename zpool_rewind_policy_t to zpool_load_policy_t
illumos/illumos-gate@5dafeea3eb
We want to be able to pass various settings during import/open of a pool,
which are not only related to rewind. Instead of adding a new policy and
duplicate a bunch of code, we should just rename rewind_policy to a more
generic term like load_policy.
For instance, we'd like to set spa->spa_import_flags from the nvlist,
rather from a flags parameter passed to spa_import as in some cases we want
those flags not only for the import case, but also for the open case. One
such flag could be ZFS_IMPORT_MISSING_LOG (as used in zdb) which would
allow zfs to open a pool when logs are missing.

The idea of Storage Pool Checkpoint (aka zpool checkpoint) deals with
exactly that. It can be thought of as a “pool-wide snapshot” (or a
variation of extreme rewind that doesn’t corrupt your data). It remembers
the entire state of the pool at the point that it was taken and the user
can revert back to it later or discard it. Its generic use case is an
administrator that is about to perform a set of destructive actions to ZFS
as part of a critical procedure. She takes a checkpoint of the pool before
performing the actions, then rewinds back to it if one of them fails or puts
the pool into an unexpected state. Otherwise, she discards it. With the
assumption that no one else is making modifications to ZFS, she basically
wraps all these actions into a “high-level transaction”.

8940 Sending an intra-pool resumable send stream may result in EXDEV
illumos/illumos-gate@544132fce3
"zfs send -t <token>" for an incremental send should be able to resume
successfully when sending to the same pool: a subtle issue in
zfs_iter_children() doesn't currently allow this.
Because resuming from a token requires "guid" -> "dataset" mapping
(guid_to_name()), we have to walk the whole hierarchy to find the right
snapshots to send.
When resuming an incremental send both source and destination live in the
same pool and have the same guid: this is where zfs_iter_children() gets
confused and picks up the wrong snapshot, so we end up trying to send an
incremental "destination@snap1 -> source@snap2" stream instead of
"source@snap1 -> source@snap2": this fails with an "Invalid cross-device
link" (EXDEV) error.

9075 Improve ZFS pool import/load process and corrupted pool recovery
illumos/illumos-gate@6f7938128a
Some work has been done lately to improve the debugability of the ZFS pool
load (and import) process. This includes:
https://www.illumos.org/issues/7638: Refactor spa_load_impl into several functions
https://www.illumos.org/issues/8961: SPA load/import should tell us why it failed
https://www.illumos.org/issues/7277: zdb should be able to print zfs_dbgmsg's
To iterate on top of that, there's a few changes that were made to make the
import process more resilient and crash free. One of the first tasks during the
pool load process is to parse a config provided from userland that describes
what devices the pool is composed of. A vdev tree is generated from that config,
and then all the vdevs are opened.
The Meta Object Set (MOS) of the pool is accessed, and several metadata objects
that are necessary to load the pool are read. The exact configuration of the
pool is also stored inside the MOS. Since the configuration provided from
userland is external and might not accurately describe the vdev tree
of the pool at the txg that is being loaded, it cannot be relied upon to safely
operate the pool. For that reason, the configuration in the MOS is read early
on. In the past, the two configurations were compared together and if there was
a mismatch then the load process was aborted and an error was returned.
The latter was a good way to ensure a pool does not get corrupted, however it
made the pool load process needlessly fragile in cases where the vdev
configuration changed or the userland configuration was outdated. Since the MOS
is stored in 3 copies, the configuration provided by userland doesn't have to be
perfect in order to read its contents. Hence, a new approach has been adopted:
The pool is first opened with the untrusted userland configuration just so that
the real configuration can be read from the MOS. The trusted MOS configuration
is then used to generate a new vdev tree and the pool is re-opened.
When the pool is opened with an untrusted configuration, writes are disabled
to avoid accidentally damaging it. During reads, some sanity checks are
performed on block pointers to see if each DVA points to a known vdev;
when the configuration is untrusted, instead of panicking the system if those
checks fail we simply avoid issuing reads to the invalid DVAs.
This new two-step pool load process now allows rewinding pools accross
vdev tree changes such as device replacement, addition, etc. Loading a pool
from an external config file in a clustering environment also becomes much
safer now since the pool will import even if the config is outdated and didn't,
for instance, register a recent device addition.
With this code in place, it became relatively easy to implement a
long-sought-after feature: the ability to import a pool with missing top level
(i.e. non-redundant) devices. Note that since this almost guarantees some loss
Of data, this feature is for now restricted to a read-only import.

illumos/illumos-gate@5cabbc6b49https://www.illumos.org/issues/7614:
This project allows top-level vdevs to be removed from the storage pool with
“zpool remove”, reducing the total amount of storage in the pool. This
operation copies all allocated regions of the device to be removed onto other
devices, recording the mapping from old to new location. After the removal is
complete, read and free operations to the removed (now “indirect”) vdev must
be remapped and performed at the new location on disk. The indirect mapping
table is kept in memory whenever the pool is loaded, so there is minimal
performance overhead when doing operations on the indirect vdev.
The size of the in-memory mapping table will be reduced when its entries
become “obsolete” because they are no longer used by any block pointers in
the pool. An entry becomes obsolete when all the blocks that use it are
freed. An entry can also become obsolete when all the snapshots that
reference it are deleted, and the block pointers that reference it have been
“remapped” in all filesystems/zvols (and clones). Whenever an indirect block
is written, all the block pointers in it will be “remapped” to their new
(concrete) locations if possible. This process can be accelerated by using
the “zfs remap” command to proactively rewrite all indirect blocks that
reference indirect (removed) vdevs.
Note that when a device is removed, we do not verify the checksum of the data
that is copied. This makes the process much faster, but if it were used on
redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy
the wrong data, when we have the correct data on e.g. the other side of the
mirror. Therefore, mirror and raidz devices can not be removed.

The current checks in zfs_ioc_rollback() would not allow that because the

EINVAL is returned when a dataset does not have any snapshots, so there is

Although the code in zfs_do_rollback checks for that condition in advance, it's

Since we support whole-disk configuration for boot pool, we also will need
whole disk support with UEFI boot and for this, zpool create should create efi-

I have borrowed the idea from oracle solaris, and introducing zpool create -
B switch to provide an way to specify that boot partition should be created.
However, there is still an question, how big should the system partition be.
For time being, I have set default size 256MB (thats minimum size for FAT32
with 4k blocks). To support custom size, the set on creation "bootsize"
property is created and so the custom size can be set as: zpool create B -
o bootsize=34MB rpool c0t0d0
After pool is created, the "bootsize" property is read only. When -B switch is
not used, the bootsize defaults to 0 and is shown in zpool get output with
value ''. Older zfs/zpool implementations are ignoring this property.

The problem is that consumers of `libZFS_Core` that forget to call
`libzfs_core_init()` before calling any other function of the library
are having a hard time realizing their mistake. The library's internal
file descriptor is declared as global static, which is ok, but it is not
initialized explicitly; therefore, it defaults to 0, which is a valid
file descriptor. If `libzfs_core_init()`, which explicitly initializes
the correct fd, is skipped, the ioctl functions return errors that do
not have anything to do with `libZFS_Core`, where the problem is
actually located.
Even though assertions for that existed within `libZFS_Core` for debug
builds, they were never enabled because the `-DDEBUG` flag was missing
from the compiler flags.
This patch applies the following changes:
1. It adds `-DDEBUG` for debug builds of `libZFS_Core` and `libzfs`,
to enable their assertions on debug builds.
2. It corrects an assertion within `libzfs`, where a function had
been spelled incorrectly (`zpool_prop_unsupported()`) and nobody
knew because the `-DDEBUG` flag was missing, and the preprocessor
was taking that part of the code away.
3. The library's internal fd is initialized to `-1` and `VERIFY`
assertions have been placed to check that the fd is not equal to
`-1` before issuing any ioctl. It is important here to note, that
the `VERIFY` assertions exist in both debug and non-debug builds.
4. In `libzfs_core_fini` we make sure to never increment the
refcount of our fd below 0, and also reset the fd to `-1` when no
one refers to it. The reason for this, is for the rare case that
the consumer closes all references but then calls one of the
library's functions without using `libzfs_core_init()` first, and
in the mean time, a previous call to `open()` decided to reuse
our previous fd. This scenario would have passed our assertion in

We can run into a problem where we call into zfs_mount, which in turn calls
is_dir_empty, which opens the directory to try and make sure it's empty. The
issue with the current approach is that it holds the directory open while it
traverses it with readdir, which, due to subtle interaction with the Java JVM,
vfork, and exec can cause a tricky race condition resulting in zfs_mount
failures.
The approach to resolving the issue in this patch is to drop the usage of
readdir altogether, and instead rely on the fact that ZFS stores the number of
entries contained in a directory using the st_size field of the stat structure.
Thus, if the directory in question is a ZFS directory, we can check to see if
it's empty by calling stat() and inspecting the st_size field of structure
returned.
===============================================================================
The root cause appears to be an interesting race between vfork, exec, and
zfs_mount's usage of O_CLOEXEC when calling openat. Here's what is going on:
1. We call zfs_mount, and this in turn calls openat to check if the directory
is empty, which results in opening the directory we're trying to mount onto,
and increment v_count.
2. As we're in the middle of reading the directory, vfork is called by the JVM
and proceeds to exec the jspawnhelper utility. As a result of the vfork, we
take an additional hold on the directory, which increments v_count a second
time. The semantics of vfork mean the parent process will wait for the child
process to exit or exec before the parent can continue; at this point the
parent is in the middle of zfs_mount, reading the directory to determine if
it's empty or not.
3. The child process exec-ing jspawnhelper gets to the relvm call within
exec_args (which is called by exec_common). relvm is the function that releases
the parent process, allowing the parent to proceed. The problem is, at this
point of calling relvm, the child hasn't yet called close_exec which is
responsible for closing the file descriptors inherited from the parent process

$ sudo zinject -d spare-1 -A degrade foo
cannot find device 'spare-1' in pool 'foo'
$ sudo zpool clear foo spare-1
cannot clear errors for spare-1: no such device in pool
Even though there was nothing to clear, those commands shouldn't have
reported an error. by contrast, trying to clear "raidz1-0" works just fine:
$ sudo zpool clear foo raidz1-0

We want to be able to run channel programs outside of synching context.
This would greatly improve performance of channel program that just gather
information, as we won't have to wait for synching context anymore.
This feature should introduce the following:
- A new command line flag in "zfs program" to specify our intention to
run in open context.
- A new flag/option within the channel program ioctl which selects the
context.
- Appropriate error handling whenever we try a channel program in
open-context that contains zfs.sync* expressions.
- Documentation for the new feature in the manual pages.

These return the jail ID and jail name for the traced process,
respectively, and are analogous to "zonename" on Solaris/illumos.
"zonename" is now aliased to "jailname".
Also add some stress tests for the new variables.

The bug would cause incorrect behaviour when attempting to override
an already set environment variable with -x setenv, as long as the
variable is not the last one in the array.

This allows one to override the environment for processes created with
dtrace -c. By default, the environment is inherited.
This support was originally merged from illumos in r249367 but was lost
when the commit was later reverted and then brought back piecemeal.

When we encounter a USDT probe in a weak symbol, we emit an alias for
the probe function symbol. Such aliases are named differently from the
aliases we emit for probes in local functions, so make sure to take that
difference into account when resizing the output object file's string
table. Otherwise, we underrun the string table buffer.
PR: 223680
Previously some unimplemented libdtrace routines printed the function,
file and line number, followed by "DOODAD." That is not particularly
informative, so replace it with a message reporting the actual issue.

du(1), df(1m), ls(1), and swap(1m) all include a copy (it appears literally
copied) of the 'number_to_scaled_string' function in their source. This should
be moved to a shared library and all 4 commands should use this instead.
FreeBSD note: of all libcmdutils functionality ZFS (and other illumos
contrib code) currently uses only nicenum() function (which is similar
to humanize_number but has some formatting differences). For this
reason I decided to not port the whole library. As a result, nicenum.c
from libcmdutils is compiled into libzfs and libzpool. This is a bit
ugly, but works. If one day we are forced to create libillumos, then
the file should be moved to that library.

Previously, zpool_read_all_labels was trying to do 256KB reads, which are
greater than the default MAXPHYS and therefore must go through the slow,
unsafe AIO path. Shrink these reads to 112KB so they can use the safe, fast
AIO path instead.

the current libzfs only allows simple disk and mirror setup for boot pool, as
loader does support booting from raidz, this feature will remove raidz
restriction from boot pool setup.
FreeBSD note: we have long supported this feature, this commit only
removes a small difference in libzfs.
