When valgrind usage is desired by user (--enable-valgrind-pool)
skip playing/closing/reopenning with descriptors - it makes
valgridng useless.

c698ee14bb scripts: introduce blkdeactivate
blkdeactivate - utility to deactivate block devices

Traverses the tree of block devices and tries to deactivate them.
Currently, it supports device-mapper-based devices together with LVM.
See man/blkdeactivate.8 for more info.

It is targeted for use during shutdown to properly deactivate the
whole block device stack - systemd and init scripts are provided as
well. However, it might be used directly on command line too.

Please, see the commentary at the top of the blkdeactivate script
for dependencies and versions of other utilities required.

f8781ea6a0 systemd: add deps to order units more properly
lvm2-activation-early.service (generated by activation generator) should
be ordered before cryptsetup.target.

lvm2-monitor.service should be ordered after lvm2-activation.service,
if used. The lvm2-activation.service will replace fedora-storage-init.service
and fedora-storage-init-late.service in the end, but let's have it
prepared now.

abb07a1b5e libdm: remove dm dev without error even with malformed UUID
On each ioctl return, the device UUID is decoded from \xNN format.
If the UUID of the device being *removed* is malformed (e.g. it
hasn't been corrected before), just remove it without any error
as the UUID is not needed anymore - the device is gone anyway.

Otherwise a misleading error message would be issued just after
the removal:
  # dmsetup remove test
  The UUID "a b" should be mangled but it contains blacklisted characters.
  Command failed

b296e30f98 TEST: Add lvchange-partial.sh and vgchange-partial.sh to the test suite
Commit 3501f17fd0 enables a limited set
of metadata updates for partial LV/VGs when issuing lvchange or vgchange.
These tests verify those changes operate as intended.

3501f17fd0 [lv|vg]change: Allow limited metadata changes when PVs are missing
A while back, the behavior of LVM changed from allowing metadata changes
when PVs were missing to not allowing changes.  Until recently, this
change was tolerated by HA-LVM by forcing a 'vgreduce --removemissing'
before trying (again) to add tags to an LV and then activate it.  LVM
mirroring requires that failed devices are removed anyway, so this was
largely harmless.  However, RAID LVs do not require devices to be removed
from the array in order to be activated.  In fact, in an HA-LVM
environment this would be very undesirable.  Device failures in such an
environment can often be transient and it would be much better to restore
the device to the array than synchronize an entirely new device.

There are two methods that can be used to setup an HA-LVM environment:
"clvm" or "tagging".  For RAID LVs, "clvm" is out of the question because
RAID LVs are not supported in clustered VGs - not even in an exclusively
activated manner.  That leaves "tagging".  HA-LVM uses tagging - coupled
with 'volume_list' - to ensure that only one machine can have an LV active
at a time.  If updates are not allowed when a PV is missing, it is
impossible to add or remove tags to allow for activation.  This removes
one of the most basic functionalities of HA-LVM - site redundancy.  If
mirroring or RAID is used to replicate the storage in two data centers
and one of them goes down, a server and a storage device are lost.  When
the service fails-over to the alternate site, the VG will be "partial".
Unable to add a tag to the VG/LV, the RAID device will be unable to
activate.

The solution is to allow vgchange and lvchange to alter the LVM metadata
for a limited set of options - --[add|del]tag included.  The set of
allowable options are ones that do not cause changes to the DM kernel
target (like --resync would) or could alter the structure of the LV
(like allocation or conversion).

470d1a2f54 dmsetup: also apply 'mangle' command for UUIDs
Compared to names, UUIDs can't be renamed once they are created
for a device. The 'mangle' command will just issue an error message
about a need for manual intervention in this case - reactivating the
device (remove + create) does the job as the defualt mangling mode
used is "auto" and that will assign a correct mangled form the UUID.
