4a59dda8aa Add experimental code for activation of thinp targets
No dm messages yes - just a base functionality in the steps of other targets.
For now usable only for debugging and tracing.

New dm_tree_node_add_thin_pool_target() and  dm_tree_node_add_thin_target()
This API is highly experimental and unstable for now.

e0948b5825 Introduce revert_lv for better pvmove cleanup.
(One further fix needed to remove the stray pvmove LVs left behind.)

691157a71e Replace incomplete pvmove activation failure recovery code with a message.
As it stands, the recovery code can make things worse sometimes so it's
better to insist on a proper 'pvmove --abort' cleanup.

e63febe5ec Abort if _finish_pvmove suspend_lvs fails instead of cleaning up incompletely.
Change suspend_lvs to call vg_revert internally.
Change vg_revert to void and remove superfluous calls after failed vg_commit.

57f1027a03 Use execvp for clvmd restart
Since execve passed only NULL as environ, we had lost all environment vars on
restart - thus actually running  'different' clvmd then the one at start.

Preserving environ allows to restart clvmd with the same settings
(i.e. LD_LIBRARY_PATH)

Add test for second restart.

7f7e0704f6 Remove test for NULL
Since it's internal function and we always check for NULL value
before call - this is safe.

Just for case add nonnull attribute so analyzer might better
catch error.

1dd5dfed81 Replace test for NULL of root->child with test for NULL l
It's 100% equivalent test - since it always happen for the first iteration.
But the check for 'l' is understandable with analyzers - since analyzer
is not smart enough to deduce connection between  root->child == NULL.

bd085674b2 Restart CLVMD with same cluster manager
Add named cluster_ops to easily learn the name of the active cluster manager,
so we are able to restart singlenode manager in testing.

Add simple test for clvmd -S  (restart) and -R (refresh)
(though it needs some extensions).

71ee4b8d25 Fix log_error() usage

Add missing log_error if allocation would fail for unknown segtype.

1fd620a436 Allow overwrite for VERIFY_UDEV
When running tests it might be useful to have an override option when
testing on real /dev  and some broken system (i.e. Debian and its rules).

So one can use:

LVM_TEST_DEVDIR=/dev LVM_VERIFY_UDEV=1 make check

48b9cbab24 Use Makefile for daemmons/common library.
Next iteration for better fit of lvmetad compilation.

Move build of libdaemon.a into common subdir Makefile.
libdaemon.a is device-mapper target.

Build and install lvmetad as lvm2 target.

4c71c99934 Detect unusable nodes on fs
Test whether nodes could be used on given filesystem where TMP
dir is being used and skip teardown quicker in fail case.
(makes the problem quickly obvious if you try to such fs).

Skip teardown_dev if we have not created any devs yet.

and do not mkdir /dev/mapper dir  when LVM_TEST_DEVDIR is set.

Drop this test from t-000-basic.sh.

8ed5c47ce5 CLVMD support for LVM_CLVMD_BINARY and LVM_BINARY
Read 2 environmental vars to learn about overide position for
CLVMD and LVM binaries.

We support LVM_BINARY in other script - and this way we could easily
test restart in our test-suite.

9c2095311e CLVMD bugfix support for args -S -E
Bugfix:
Add (most probably unfinished) support for -E arg with list of exclusive
locks.  (During clvmd restart all exclusive locks would have been lost and
in fact, if there would have been an exclusive lock, usage text would be
printed and clvmd exits.)

Instead of parsing list options multiple times every time some lock UUID is
checked - put them straight into the hash table - make the code easier to
understand as well.

Remove  was_ex_lock() function (replaced with dm_hash_lookup()).

Swap return value for get_initial_state() (1 means success).

Update man pages and usage info for -E option.

638409a573 Replace open_count check with holders/mounted_fs check on lvremove path.
Before, we used to display "Can't remove open logical volume" which was
generic. There 3 possibilities of how a device could be opened:
  - used by another device
  - having a filesystem on that device which is mounted
  - opened directly by an application

With the help of sysfs info, we can distinguish the first two situations.
The third one will be subject to "remove retry" logic - if it's opened
quickly (e.g. a parallel scan from within a udev rule run), this will
finish quickly and we can remove it once it has finished. If it's a
legitimate application that keeps the device opened, we'll do our best
to remove the device, but we will fail finally after a few retries.

def057522f Add dm_device_has_holders fn to to check use of the device by another device.
Add dm_device_has_mounted_fs fn to check mounted filesystem on a device.

This requires sysfs directory to be correctly set via dm_set_sysfs_dir
(/sys by default). If sysfs dir is not used or it's set incorrectly,
dm_device_has_{holders,mounted_fs} will return 0!
