Add "lvm2-activation-generator: " prefix for all kmsg messages written by
lvm2-activation-generator so we can identify the message in global system log.
We need to have Ceph RBD devices mapped first before use in a stack
where LVM is on top so make sure rbdmap.service is called before
generated lvm2-activation-net.service.
On shutdown, we need to stop blk-availability first before we stop the
rbdmap.service.

It's no longer needed. Clustered VGs are now handled in
the same way as foreign VGs, and as shared VGs that
can't be accessed:
- A command processing all VGs sees a clustered VG,
prints a message ("Skipping clustered VG foo."),
skips it, and does not fail.
- A command where the clustered VG is explicitly
named on the command line, prints a message and fails.
"Cannot access clustered VG foo, see lvmlockd(8)."
The option is listed in the set of ignored options for
the commands that previously accepted it. (Removing it
entirely would cause commands/scripts to fail if they
set it.)
Since we are using "DefaultDependencies=no" we do not get automatic STOP
job on socket connection - so automatically refuse connection on
shutdown by adding this Conflict definition to socket Unit.
Shared VGs will generally be started and activated by
the resource agent. Without the agent, this script doesn't
have a good way to know which LVs to activate.
The device-mapper directory now holds a copy of libdm source. At
the moment this code is identical to libdm. Over time code will
migrate out to appropriate places (see doc/refactoring.txt).
The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).
All code using libdm should now use the version in device-mapper.
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/
We always preferred and recommended socket activation for our services
so remove the Install section in related .service units which are unused
in this case and keep only the Install section in associated .socket
units.

Replace lowercase @sbindir@ with @SBINDIR@ which contains
fully decoded path.
Same with @usrsbindir@ which is also used with clvmd and cmirrord.
Also handle SYSCONFDIR for EnvironmentFile.
Patch fixes generated unit files with strings like:
ExecStart=${exec_prefix}/sbin/lvm
split resize_crypt function in two.
a) Detect proper dm-crypt device type and count new --size
value for cryptsetup resize command.
b) Perform the resize
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).

There's nothing special about /boot other than it's used during boot.
But when blkdeactivate is called either on all devices or including a
device where the /boot is on top, we should also include this mount
point when doing unmount before deactivation of supported devices.
The new blkdeactivate -r|mdraidoption wait causes blkdeactivate to wait
for any resync/recovery/reshape that is currently in progress before
deactivating the device.
If this option is used, blkdeactivate calls mdadm -W|--wait before
mdadm -S|--stop.
Revert dc50f2f4a0.
We're canonicalizing/escaping the names here and we're reusing the
variable name so the code doesn't need to use extra variables and
further assignments that may confuse us. Let's keep the code simple.
The
local name=(...$name)
is not the same as
local name
name=(...$name)
(I know various code-checking tools fuss about this and recommend
the 2nd way, but let's ignore those tools' nitpicking here please.)
There was a typo in blkdeactivate --dmoption/--lvmoption/mpathoption,
it had missing "s" at the end and it was not recognized properly, only
short names for the options (-d/-l/-m).
Drop 'DMEVENT' make variable and use BUILD_DMEVENTD like with other daemons.
NOTE: by default we do not build dmeventd - maybe time to change
as lot of build targets basically do need dmeventd...
Switch to use SYSTEMD_LIBS and avoid linking systemd library with
every linked tool when dbus notification are enabled.
(TODO add missing testing for lib presence)
Commit 1fe4f80e45 in current version
introduced regression for a terminal user, as he could not enter 'n'
as answer. Add missing break for this case (No whats_new).
When 'fsadm' was running without terminal (i.e. pipe), it's been
automatically working like in '--yes'.
Detect terminal and only accept empty "" input in this mode.
Add more validation to catch mainly renamed devices, where
filesystem utils are not able to handle devices properly,
as they are not addressed by major:minor by rather via some
symbolic path names which can change over time via rename operation.
Since we add more validation to 'detect_mounted' function make sure
we always use it even with 'resize' action, so numerous validations
are not skipped.
We have to unset the LoadState variable from previous use when we check
for systemd unit state. We use this variable to check if systemd services
are loaded or not and if it is loaded, we issue systemctl commands to
enable/disable and start/stop the service. We don't issue these commands
if the unit is not loaded to avoid error messages which may confuse users.
The blkdeactivate script processes MD devices too so we should unmount
any mount point on top of an MD device if blkdeactivate -u|--umount is
called.
Diagnosed and reported by: Rick Warner <rick@microway.com>
See also https://bugzilla.redhat.com/show_bug.cgi?id=1410585.
If blkdeactivate finds out that the device on top of device stack
is already unmounted, it still proceeds with device stack deactivation
underneath now.
This situation can happen if blkdeactivate is started and the mount
point is unmounted in parallel by chance (so when blkdeactivate
gets the the actual umount call, the device is not mounted anymore).
Before, the blkdeactivate added such device to skip list which caused
all the stack underneath to be skipped too on deactivation. Now, we
proceed just as if blkdeactivate did the umount itself.
For example, in the example below, the vg-lvol0 is mounted on /mnt/test
when blkdeactivate is called, but it gets unmounted in parallel later
on when blkdeactivate gets to the actual umount call.
Before this patch (vg-lvol0 underneath not deactivated):
$ blkdeactivate -u
Deactivating block devices:
[UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... skipping
With this patch applied (vg-lvol0 underneath still deactivated):
$ blkdeactivate -u
Deactivating block devices:
[UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... already unmounted
[LVM]: deactivating Logical Volume vg/lvol0... done
We shouldn't be losing pvscans just because of the fact that the
underlying device (PV) appears and disappears quickly in the system,
otherwise lvmetad may not see the device if it appears again (or it may
still keep the device in cache even it's already gone).
