lvmlockd: use persistent reservations for recovery with sanlock
The process of using persistent reservations for recovery:
host A owns a lock
host A fails
host B requests the lock
host B request fails because A owns the lock
host A enters the FAIL state in sanlock
host B retries the lock, and sees owner A is failed
host B runs lvmpersist to remove the PR key of host A
host B tells sanlock that host A is dead
host B retries the lock, which is now granted by sanlock
The new option: --setlockargs persist,notimeout
adds "persist" and "notimeout" components to the
lock_args string in the VG metadata, viewable with
vgs -o+lockargs. The option is available in vgcreate
or vgchange.
. "persist" tells lvmlockd to remove the PR key of
a failed host, by running lvmpersist, and set the
sanlock host state to "dead".
. "notimeout" tells lvmlockd to configure sanlock
leases to not time out. sanlock does not use the
watchdog to protect leases that do not time out.
With this combination, PR removal replaces the watchdog
for fencing hosts with expired leases that are blocking
other hosts.
The lock_args version component is "2.0.0" when
these new settings are used, otherwise remains
"1.0.0". Previous lvm versions will not start a
VG with lockargs version 2.
Requires sanlock version 4.2.0 or later.

2. run, which removes pr key from the VG devices,

This is necessary if another PR key is registered on the device
(which likely doesn't happen in the normal usage pattern, but is

When another key exists, removing the local PR key will cause the
machine to lose the ability to write VG metadata to the device.

is written for vgremove. The prepare step must remain at the beginning
of the command, while the list of PVs in the VG still exists.

dmeventd: fixes for grace period timer
Fix several problems in recent dmeventd grace period enhancement:
1. **Timer reset bug**: Threads exiting grace period were starting
time period with rather random time 'offset' causing change
in behavior and firing monitor action in non-deterministic time.
Reset timer (next_time = current_time + timeout) AFTER grace
period wait.
2. **Device identity verification**: Add inode tracking to prevent
incorrect thread reuse when device UUID is recycled. Grace period
thread lookup now verifies device inode matches to ensure same
physical device. This avoid reusing of monitored values for
a different device.
'diskseq' was also considered as unique identifier, but inode
check seems to be easier to check and is not 'so new'.
Also another solution could have been to change dmeventd protocol,
and introduce supend/resume calls - but this could be another source
of problem.
3. **Signal handling order**: Move SIGALRM reset to occur BEFORE
entering grace period instead of after. This prevents potential
error path trouble that may have shutdown reused thread causing
the actual monitoring to be silently lost.
4. **Event state cleanup**: Clear current_events before grace period
to prevent stale event processing after thread reuse.

test integrity.sh use writemostly to reliably detect mismatches
The test shell/integrity.sh creates raid arrays, corrupts one of the
legs, then reads the array and verifies that the corruption was
corrected. Finally, the test tests that the number of mismatches on the
corrupted leg is non-zero.
The problem is that the raid1 implementation may freely choose which leg
to read from. If it chooses to read the non-corrupted leg, the corruption
is not detected, the number of mismatches is not incremented and the test
reports this as failure.
Fix this failure by marking the non-corrupted leg as "writemostly", so
that the kernel doesn't try to read it (it reads it only if it finds

test integrity.sh cannot rely on mismatches being detected for raid1
The test shell/integrity.sh creates raid arrays, corrupts one of the
legs, then reads the array and verifies that the corruption was
corrected. Finally, the test tests that the number of mismatches on the
corrupted leg is non-zero.
The problem is that the raid1 implementation may freely choose which leg
to read from. If it chooses to read from the non-corrupted leg, the
corruption is not detected, the number of mismatches is not incremented
and the test reports this as a failure.
Fix the test by not checking the number of integrity mismatches for
raid1.

vgsplit: fix check for not splitting an LV between two VGs
Fix check for not splitting an LV between two VGs in case
where the LVs contains an internal layer.
For example, integrity layer for RAIDs and splitting a PV that
is not part of the RAID LV at all (sdc here):
❯ vgcreate vg /dev/sda /dev/sdb /dev/sdc
Volume group "vg" successfully created
❯ lvcreate -l1 -m1 --type raid1 --raidintegrity y vg /dev/sda /dev/sdb
Logical volume "lvol0" created.
Before this patch:
❯ vgsplit vg vg2 /dev/sdc
Logical volume vg/lvol0_rimage_0 (part of lvol0) must be inactive.
❯ vgchange -an vg
0 logical volume(s) in volume group "vg" now active
❯ vgsplit vg vg2 /dev/sdc
Can't split LV lvol0_rimage_0 between two Volume Groups
With this patch applied:
❯ vgsplit vg vg2 /dev/sdc
New volume group "vg2" successfully split from "vg"

dmeventd: add thread grace period for monitoring
Add thread reuse mechanism to reduce overhead when devices are frequently
registered/unregistered by introducing a configurable grace period where
monitoring threads wait for potential reuse before termination.
Key changes:
- Add -g option to configure grace period (0-300 seconds, default: 10s)
- Introduce DM_THREAD_GRACE_PERIOD state for threads awaiting reuse
- Implement thread reuse for matching device/dso combinations
- Add pthread condition variables and mutexes for grace period synchronization
- Add thread usage counter and enhanced debug logging
- Add _reset_pending_signal() to handle SIGALRM cleanup on thread reuse
- Refactor _monitor_thread() to support grace period workflow
- Update timeout thread to skip non-running threads
- Simplify thin plugin logging
This optimization significantly reduces thread creation/destruction overhead
in scenarios with rapid device registration/unregistration cycles, such as
creating snapshots of thin volumes, while maintaining proper cleanup and
thread safety.

dmeventd: add device existence check
Add device existence check after successful wait ioctl to prevent
processing events on removed devices.
When dm_task_run() succeeds on a WAITEVENT ioctl, the success might
actually indicate that the device was removed rather than a genuine
device event. Without this check, dmeventd would attempt to process
ERROR events on non-existent devices, leading to unnecessary error
commands and log noise.
This fix adds a _fill_device_data() call immediately after successful
wait completion to verify the device still exists. If the device is
gone, execution jumps to the existing ENXIO error path which properly
handles device disappearance.
Note: Future kernel versions may return ENXIO directly from the wait
ioctl when devices are removed, making this workaround unnecessary.
Until then, this extra INFO ioctl provides the needed verification.

scripts: refactor lvmdump directory validation
Break down complex one-liner directory check into explicit steps with
clear error messages and comments.
The original code used a dense subshell expression combining multiple
tests with logical operators, making it difficult to understand and
maintain. This refactoring separates the logic into:
1. Check directory accessibility (read/write/execute permissions)
2. Check if directory is empty (including hidden files)
Each check now has a specific error message, making it easier for users
to understand what went wrong. The functionality remains identical, but
the code is now more maintainable and debuggable.
Changes:
- Split accessibility and emptiness checks into separate if statements
- Add descriptive comments explaining each validation step
- Provide specific error messages for different failure conditions
- Maintain original behavior including dotglob/nullglob handling

vdo: fix 32b portability issue in vdo_header struct
Replace size_t with uint64_t in struct vdo_header to ensure consistent
64-bit size field across all architectures.
On 32-bit platforms, size_t is only 4 bytes, which causes incorrect
structure layout when reading VDO metadata that expects a 64-bit size
field. This fix ensures the VDO header structure maintains the same
binary layout regardless of target architecture.
While 32-bit architectures are not officially supported for VDO,
this change improves code correctness and prevents potential issues
during cross-compilation or when building on 32-bit development
environments.
