146745ad88 device: Separate errors for dev not found and filtered.
Replaced the confusing device error message "not found (or ignored by

(Later we should be able to say which filter.)

Left the the liblvm code paths alone.

e02e5b0c5b activation: fix activation lock
Activation lock has a primary purpose to serialize locking of individual
LV in case there is no other protecting mechanism for parallel
execution.

However in the case an activated LV is composed from several other LVs,
noone should be able to manipulate with those LVs as well.

This patch add a very 'naive' global VG activation locking in this case.
In the future we may introduce smarter function detecting minimal closed
graph components if this will appear as bottleneck

Patch checks if the  VG Write lock is held - in this case we do not
need any more locking - command has exclusive access to VG.

In case we have clustered VG and we are activating an LV which does not
need other LVs - we also do not need any more locks.

In all other cases take respective lock - for single LV - use lvid,
for complex LVs  use vgname.

5f13e33d54 lvcreate: fix region size on striped RaidLVs
Creating striped RaidLVs with lv size not divisible by region size
caused the region size to be adjusted:

# lvcreate   --type raid5 -n region_check.32.00m_3 -i 3 -L 1g --nosync -R 32.00m raid_sanity
  Using default stripesize 64.00 KiB.
  Rounding size 1.00 GiB (256 extents) up to stripe boundary size <1.01 GiB(258 extents).
  WARNING: New raid5 won't be synchronised. Don't read what you didn't write!
  Using reduced mirror region size of 8.00 MiB
  Logical volume region_check.32.00m_3 created.

Fix by not imposing "mirror" constraints on "raid".

486ed10848 vgmerge: Fix intermediate metadata corruption
vgmerge suffers from a similar problem to the one fixed in commit
8146548d25 ("vgsplit: Fix intermediate
metadata corruption.")

When merging, splitting or renaming VGs, use a new PV status flag
PV_MOVED_VG to mark the PVs that hold metadata with the old VG name and
use this to provide PV-level granularity instead of incorrectly assuming
all PVs in the VG are the same.

a781b1c178 dmeventd: ensure systemd service gets stopped on shutdown
Add these for dmeventd systemd unit (dm-event.service):

  Before: shutdown.target
  Conflicts: shutdown.target

This will cause the dmeventd to be properly stopped at shutdown (after
all the dmeventd clients unregistered their devices from monitoring)
with dm-event.service's stop action (there's no direct action defined
for the "stop" so systemd sends SIGTERM instead).

Before, we let dmeventd to get killed only as part of the very last
SIGTERM/SIGKILL for all the remaining processes late in the shutdown
sequence so we may have missed some logs if dmeventd encountered an
error during its shutdown (logging facilities are already off at this
late time in shutdown sequence).

9940c2f754 dmeventd: schedule exit on break
When dmeventd receives SIGTERM/INT/HUP/QUIT it validates if exit is possible.
If there was any device still monitored, such exit request used to
be ignored/refused. This 'usually' worked reasonably well, however if there
is very short time period between last device is unmonitored and signal
reception - there was possibility such EXIT was ignored, as dmeventd has
not yet got into idle state even commands like 'vgchange -an' has already
finished.

This patch changes logic towards scheduling EXIT to the nearest
point when there is no monitored device.

EXIT is never forgotten.

NOTE: if there is only a single monitored device and someone sends
SIGTERM and later someone uses i.e. 'lvchange --refresh' after
unmonitoring dmeventd will exit and new instance needs to be
started.

8146548d25 vgsplit: Fix intermediate metadata corruption.
Changing the VG of a PV uses the same on-disk mechanism as vgrename.
This relies on recognising both the old and new VG names.  Prior to this
patch the vgsplit code incorrectly provided the new VG name twice
instead of the old and new ones.  This lead the low-level mechanism not
to recognise the device as already belonging to a VG and so paying no
attention to the location of its existing metadata, sometimes partly
overwriting it and then later trying to read the corrupt metadata and
issuing a checksum error.

7a6e438df8 lvmdbusd: Ensure vg_uuid is present
In some cases we are seeing where there are no VGs, but the data returned from
lvm shows that the PVs have the following for the VG:

"vg_name":"[unknown]", "vg_uuid":""

The code was only checking for the exitence of the VG name and we called into
the function get_object_path_by_uuid_lvm_id which requires both the VG name and
the LV name to exist (asserts this) which results in the following stack trace:

e3965d392c lvmdbusd: Fix hang in MThreadRunner
When executing in the main thread, if we encounter an exception we
will bypass the notify_all call on the condition and the calling thread
never wakes up.

@staticmethod
    def runner(obj):
        # noinspection PyProtectedMember
Exception thrown here
 ----> obj._run()
So the following code doesn't run, which causes calling thread to hang
	with obj.cond:
            obj.function_complete = True
            obj.cond.notify_all()

Additionally for some unknown reason the stderr is lost.
Best guess is it's something to do with scheduling a python function
into the GLib.idle_add.  That made finding issue quite difficult.
