Deactivate converted volume to pool early, so the conversion
exits early and does not leave some already created metadata
volumes that needed manual cleanup by user after command
aborted its conversion operation when the converted volume
was actually in-use (i.e. when user tried to convert
a mounted LV into a thin-pool, 2 extra volumes needed removal).
Device quirks may cause sysfs wwid file to change what it
displays, from a bogus eui... string to an nvme... string.
The old wwid may be saved in system.devices, so recognizing
the device requires finding the old value from libnvme.
After matching the old bogus value using libnvme, system.devices
is updated with the current sysfs wwid value.
All block devices have a disk sequence number assigned (an ever-increasing 64 bit
sequence number) since kernel v5.15 (February 2021). The number is exported through
/sys/block/<disk>/diskseq property and also as DISKSEQ udev event variable.
The diskseq helps with referencing a device throughout its existence in
race-free way.
By default, the /usr/lib/udev/rules.d/60-persistent-storage.rules set
/dev/disk/by-diskseq/<diskseq> symlink for each block device. However,
these rules do not apply for DM devices because we manage the symlinks
ourselves in 13-dm-disk.rules where it properly follows the
DM_UDEV_DISABLE_DISK_RULES flag, among other things.
Add a rule to 13-dm-disk.rules to create the /dev/disk/by-diskseq/<diskseq>.
Since commit d106ac04ab ("configure.ac: use LIBSYSTEMD"),
lvmlockd is not built with SD_NOTIFY by default but depending
on LIBSYSTEMD_LIBS. There are three prerequisites of
nonempty LIBSYSTEMD_LIBS:
NOTIFYDBUS_SUPPORT, SYSTEMD_JOURNAL_SUPPORT and SYSTEMD_JOURNAL_SUPPORT.
If ./configure is called with options ' --disable-systemd-journal
--disable-app-machineid --enable-lvmlockd-sanlock
--disable-notify-dbus', the lvmlockd built is without sd_notify
support which causes hang of start lvmlockd service in notify type.
This commit adds options disable-sd-notify and enable-sd-notify.
The default value is autodetected and when the lvm2 is build with
systemd then sd-notify is enabled.
If systemd/sd-daemon.h is existed, call PKG_CHECK_MODULES libsystemd.

Also fix the use of --all that was mistakenly included
as an accepted option for vgdisplay and two cases of pvdisplay
in commit "tools: enhance lvdisplay vgdisplay pvdisplay"
Remove --noudevsync option - as this breaks synchronization with
udev which is necessary when trying to i.e. create _rmeta_3
and wipe it - as the symlinks must be present for wiping.
So if there was some other issue (behind the comment) - we need to
check for the problem elsewhere instead of disabling udev sync.
Automatically use --enable-notify-dbus when building lvmlockd
if not configured otherwise by a configure user -
as the lvmlockd.service is notify based.
Split description for display commands so we can better describe
it's usage and combination of individual options in man page.
Now we can separately describe:
lvdisplay, lvdisplay -c, lvdisplay -C
vgdisplay, vgdisplay -c, vgdisplay -C
pvdisplay, pvdisplay -c, pvdisplay -C
TODO: Drop validation from command code itself.
Update the _print_man_option_desc() to also handle common parts
as the initial text without any specified section and also
add support for '#\n' to be able to revert to common part.
Avoid printing lvm2 command trace, if the test finds the 'dmeventd'
was started unxpectedly during testing as the last command is hardly
ever responsible for this
Also reorder some messages when doing teardown of devices.
Do not print 'help' message from hostname command, when it does
not support option '-I'.
Since we now keep lv names valid all the time (as they are part
of radix_tree) - there is a problem with this renaming code, that
for a moment used duplicated name in vg struct.
Fix it by interating LVs backwared - which avoids breaking consitency
and also actually makes code more simple.
Add check for 'leaked' symlinks after test and trap
the case when some 'danglink' links are present.
This might be some problem with udev synchronization
or some other strange race.
All such symlinks will be also removed so they will not
influence following tests.
