7a64fff948 systemd: remove ExecStartPost from lvm2-lvmetad.service.
The ExecStartPost with pvscan --cache in lvm2-lvmetad.service
is not needed now as this is called transparently within the
first LVM command that queries lvmetad.

3877ccfe1b test: move raid test to separate tests
Revert changes to origin lvcreate-large test and use separate
test scripts for raid  - so they can be properly skipped when
kernel doesn't support raid targets.

5b07bd3f91 lvconvert: disable convertion of thin to mirrors
For now this convertions is not supported, thus disabled.
The only supported conversion for now is to create mirrored thin pools
from mirrored devices.

1da6c1495a lvm2api: fix data percent reporting for thin, snap
Use same logic for lvm2api as we use lvs reporting.
data_percent is meant to be superset for snap_percent.

9efd3fb604 RAID: Do not allow RAID LVs in a cluster volume group.
It would be possible to activate a RAID LV exclusively in a cluster
volume group, but for now we do not allow RAID LVs to exist in a
clustered volume group at all.  This has two components:
	1) Do not allow RAID LVs to be created in a clustered VG
	2) Do not allow changing a VG from single-machine to clustered
	   if there are RAID LVs present.

a27650cc98 thin: lvconvert
Update code for lvconvert.
Change the lvconvert user interface a bit - now we require 2 specifiers
--thinpool   takes LV name for data device (and makes the name)
--poolmetadata  takes LV name for metadata device.

Fix type in thin help text -z -> -Z.

Supported is also new flag --discards for thinpools.

1946a45329 libdm: reset delay flag for devs used by thin
Patch clears the flag if thin pool is stacked over mirror.

Since thin pool could be used to stack device over mirrors,
it needs resume properly i.e. mirrors with corelog which are otherwise
unconditionally skipped (for pvmove functionality).

886656e4ac RAID: Fix problems with creating, extending and converting large RAID LVs
MD's bitmaps can handle 2^21 regions at most.  The RAID code has always
used a region_size of 1024 sectors.  That means the size of a RAID LV was
limited to 1TiB.  (The user can adjust the region_size when creating a
RAID LV, which can affect the maximum size.)  Thus, creating, extending or
converting to a RAID LV greater than 1TiB would result in a failure to
load the new device-mapper table.

Again, the size of the RAID LV is not limited by how much space is allocated
for the metadata area, but by the limitations of the MD bitmap.  Therefore,
we must adjust the 'region_size' to ensure that the number of regions does
not exceed the limit.  I've added code to do this when extending a RAID LV
(which covers 'create' and 'extend' operations) and when up-converting -
specifically from linear to RAID1.

2276379a71 lib/cache/lvmetad: Refactor to use dm_config_tree in requests.
We were using daemon_send_simple until now, but it is no longer adequate, since
we need to manipulate requests in a generic way (adding a validity token to each
request), and the tree-based request interface is much more suitable for this.
