e83c4f07ca lvconvert: fix conversion attempts to linear
"lvconvert --type linear RaidLV" on striped and raid4/5/6/10
have to provide the convenient interim layouts.  Fix involves
a cleanup to the convenience type function.

As a result of testing, add missing sync waits to
lvconvert-raid-reshape-linear_to_raid6-single-type.sh.

4578411633 lvconvert: fix regression preventing direct striped conversion
Conversion to striped from raid0/raid0_meta is directly possible.

Fix a regression setting superfluous interim raid5_n conversion type
introduced by commit bd7cdd0b09.

Add new test script lvconvert-raid0-striped.sh.

117160b27e Remove lvmetad
Native disk scanning is now both reduced and
async/parallel, which makes it comparable in
performance (and often faster) when compared
to lvm using lvmetad.

Autoactivation now uses local temp files to record
online PVs, and no longer requires lvmetad.

There should be no apparent command-level change
in behavior.

b697aa9646 allocator: fix thin-pool allocation
When allocating thin-pool with more then 1 device - try to
allocate 'metadataLV' with reuse of log-type allocation for mirror LV.
It should be naturally place on other device then 'dataLV'.

However due to somewhat hard to follow allocation logic code,
it's been rejected allocation in cases where there was not
enough space for data or metadata on single PV, thus to successed,
usage of segments was mandatory.

While user may use:

allocation/thin_pool_metadata_require_separate_pvs=1

to enforce separe meta and data LV - on default settings, this is not
enable thus segment allocation is meant to work.

NOTE:

As already said - the original intention of this whole  'if()' is unclear,
so try to split this test into multiple more simple tests that are more readable.

TODO: more validation.

f2b856c994 lv_manip: do not check extents for any virtual target
Allow creation of any virtual segment type with just --virtualsize
specified without any real extent size give.

TODO: likely --type error,zero might be later enhanced to use -V
(along with -L) - but since those targets do not allocate real
space, supporting -V makes sense with them.

428514a07f Drop --ignoreskippedcluster option
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.)

e53cfc6a88 lvmlockd: update method for changing clustered VG
The previous method for forcibly changing a clustered VG
to a local VG involved using -cn and locking_type 0.
Since those options are deprecated, replace it with
the same command used for other forced lock type changes:
vgchange --locktype none --lockopt force.

9a8c36b891 Fix use of orphan lock in commands
vgreduce, vgremove and vgcfgrestore were acquiring
the orphan lock in the midst of command processing
instead of at the start of the command.  (The orphan
lock moved to being acquired at the start of the
command back when pvcreate/vgcreate/vgextend were
reworked based on pvcreate_each_device.)

vgsplit also needed a small update to avoid reacquiring
a VG lock that it already held (for the new VG name).

c4153a8dfc Remove checking for locked VGs
A few places were calling a function to check if a
VG lock was held.  The only place it was actually
needed is for pvcreate which wants to do its own
locking (and scanning) around process_each_pv.

The locking/scanning exceptions for pvcreate in
process_each_pv/vg_read can be enabled by just passing
a couple of flags instead of checking if the VG is
already locked.  This also means that these special
cases won't be enabled unknowingly in other places
where they shouldn't be used.

18259d5559 Remove unused clvm variations for active LVs
Different flavors of activate_lv() and lv_is_active()
which are meaningful in a clustered VG can be eliminated
and replaced with whatever that flavor already falls back
to in a local VG.

e.g. lv_is_active_exclusive_locally() is distinct from
lv_is_active() in a clustered VG, but in a local VG they
are equivalent.  So, all instances of the variant are
replaced with the basic local equivalent.

For local VGs, the same behavior remains as before.
For shared VGs, lvmlockd was written with the explicit
requirement of local behavior from these functions
(lvmlockd requires locking_type 1), so the behavior
in shared VGs also remains the same.
