ff769ecfe7 lvconvert: Fix reload after snapshot conversion.
At the end of lvconvert --snapshot with an active origin, the origin
gets reloaded.

Commit 57c0f72b1d ("lvconvert: use
_reload_lv on more places") accidentally replaced this with a snapshot
LV reload (which does nothing because only the origin is active).

b6dab4e059 lv_manip: rename set_lv -> wipe_lv and include signature wiping capability
Use common wipe_lv (former set_lv) fn to do zeroing as well as signature
wiping if needed. Provide new struct wipe_lv_params to define the
functionality.

Bind "lvcreate -W/--wipesignatures y" with proper wipe_lv call.

Also, add "yes" and "force" to lvcreate_params so it's possible
to apply them for the prompt: "WARNING: %s detected on %s. Wipe it? [y/n]".

729b104413 activation: continue with autoactivation if refresh fails
If the refresh fails for any reason before autoactivation, let's not
make this a stopper for autoactivation itself - just log the error
message if it appears.

The reason is that in some rare situations, we can still hit the
problem with the suspend call to fail (as already described in
commit d8085edf65, also
https://bugzilla.redhat.com/show_bug.cgi?id=1027314). The refresh
itself is done for only one reason - to refresh any dm tables
for LVs for which the underlying PVs got unplugged/disconnected
and then plugged/connected back (see also
https://bugzilla.redhat.com/show_bug.cgi?id=954061 for more info).
In this case, the major:minor pair is changed and we need to
update dm tables for LVs accordingly.

Now if refresh fails, the error is still logged, but autoactivation
continues.

8d5cff5b9b lv/vgchange: do not try to connect to lvmetad if socket absent and --sysinit -aay used
If using lv/vgchange --sysinit -aay and lvmetad is enabled, we'd like to
avoid the direct activation and rely on autoactivation instead so
it fits system initialization scripts.

But if we're calling lv/vgchange --sysinit -aay too early when even
lvmetad service is not started yet, we just need to do the direct
activation instead without printing any error messages (while
trying to connect to lvmetad and not finding its socket).

This patch adds two helper functions - "lvmetad_socket_present" and
"lvmetad_used" which can be used to check for this condition properly
and avoid these lvmetad connections when the socket is not present
(and hence lvmetad is not yet running).

6d196410fc snapshot: revert and move check to lvconvert
Revert 4777eb6872 which put
target_present check into init_snapshot_merge(). However
this function is also used when parsing metadata. So we would
get this present test performed even when target is not really
needed. So move this target_present test directly into lvconvert.

7e685e6c70 toollib: Drop the pv_read optimisation.
Only reading a single PV works correctly only in very limited circumstances.
Moreover, we can't rely on the MDA available on the PV either, since it may be
out of date in some circumstances (until now, we believed that PVs that have an
empty MDA are always orphans, but this is not 100% reliable either).

d8085edf65 pvscan: retry VG refresh before autoactivation if it fails
There's a tiny race when suspending the device which is part
of the refresh because when suspend ioctl is performed, the
dm kernel driver executes (do_suspend and dm_suspend kernel fn):

  step 1: a check whether the dev is already suspended and
          if yes it returns success immediately as there's
          nothing to do
  step 2: it grabs the suspend lock
  step 3: another check whether the dev is already suspended
          and if found suspended, it exits with -EINVAL now

The race can occur in between step 1 and step 2. To prevent
premature autoactivation failure, we're using a simple retry
logic here before we fail completely. For a complete solution,
we need to fix the locking so there's no possibility for suspend
calls to interleave each other to cause this kind of race.

This is just a workaround. Remove it and replace it with proper
locking once we have that in!

Patch makes consistent behavior for command:

dmsetup info -c non-existing-dev
&
dmsetup info non-existing-dev

Now both commands report error on stderr when they return error status
for non-existing device.

f1a42aa8ec lvconvert: use LV_TEMPORARY when necessary during lvconvert to thin pool
This is an addition to original patch for lvcreate - commit 039bdad.
The same principle applies to lvconvert where there are several steps
during which we need to wipe the existing LV that's being converted
to thin pool, making sure there's no other interference from outside (udev).

0a48137d39 pvscan: use major:minor as short form of --major and --minor arg for pvscan --cache
Before, pvscan recognized either:
  pvscan --cache --major <major> --minor <minor>
or
  pvscan --cache <DevicePath>

When the device is gone and we need to notify lvmetad about device
removal, only --major/--minor works as we can't translate DevicePath
into major/minor pair anymore. The device does not exist in the system
and we don't keep DevicePath index in lvmetad cache to make the
translation internally into original major/minor pair. It would be
useless to keep this index just for this one exact case.

There's nothing bad about using "--major <major> --minor <minor>",
but it makes our life a bit harder when trying to make an
interconnection with systemd units, mainly with instantiated services
where only one and only one arg can be passed (which is encoded in the
service name).

This patch tries to make this easier by adding support for recognizing
the "<major>:<minor>" as a shortcut for the longer form
"--major <major> --minor <minor>". The rule here is simple: if the argument
starts with "/", it's a DevicePath, otherwise it's a <major>:<minor> pair.

098896fb29 mirror/RAID: Honor mirror_segtype_default when converting from linear
1) When converting from an x-way mirror/raid1 to a y-way mirror/raid1,
the default behaviour should be to stay the same segment type.

2) When converting from linear to mirror or raid1, the default behaviour
should honor the mirror_segtype_default.

3) When converting and the '--type' argument is specified, the '--type'
argument should be honored.

catch such conditions, but errors in the tests caused the issue to go
unnoticed.  The code has been fixed to perform #2 properly, the tests
have been corrected to properly test for #2, and a few other tests
were changed to explicitly specify the '--type mirror' when necessary.
