3d9c2d86b0 Change vgmerge behavior to open/lock first vg based on alphabetical ordering.
This enforces our alphabetical lock ordering rules for vgmerge.

7c86e3909c Refactor vgmerge - combine _vgmerge_to and _vgmerge_from into _vgmerge_vg_read.
These functions are identical so should be no functional change.

af9ded781d Refactor vgmerge - create _vgmerge_from and _vgmerge_to.
These functions are really identical but for clarity I made them separate
functions in this patch.

Should be no functional change.

4c35d6dee6 Remove unneeded LOCK_NONBLOCKING from vg_read() API.
Remove unneeded LOCK_NONBLOCKING from vg_read() API and tools that
use it.  We no longer need this flag anywhere since we now automatically
set LCK_NONBLOCK inside lock_vol() if vgs_locked().
For further details, see:

    Remove NON_BLOCKING lock flag from tools and set a policy to auto-set.

    As a simplification to the tools and further liblvm, this patch pushes
    the setting of NON_BLOCKING lock flag inside the lock_vol() call.
    The policy we set is if any existing VGs are currently locked, we
    set the NON_BLOCKING flag.

At some point it may make sense to add this flag back if we get an
RFE from a liblvm user, but for now let's keep it as simple as
possible.

4c611a220a Fix vg_read() error paths to properly release upon vg_read_error().
Fix vg_read() error paths to properly release upon vg_read_error().
Note that in the iterator paths (process_each_*()), we release
inside the iterator so no individual cleanup is needed.  However there
are a number of other places we missed the cleanup.  Proper cleanup
when vg_read_error() is true should be calling vg_release(vg), since
there should be no locks held if we get an error (except in certain
special cases, which IMO we should work to remove from the code).

Unfortunately the testsuite is unable to detect these types of memory
leaks.  Most of them can be easily seen if you try an operation
(e.g. lvcreate) with a volume group that does not exist.  Error
message looks like this:
  Volume group "vg2" not found
  You have a memory leak (not released memory pool):
   [0x1975eb8]
  You have a memory leak (not released memory pool):
   [0x1975eb8]

function by following patch.)

50762c2186 agk, I recall you saying you had a massive commit pending; if you need me
to back this out so you can do that commit, let me know.  Also, if there's
an issue with the error message that's displayed, just change it in tools.h.

This causes a "device-mapper driver/module not loaded?" error message to
be displayed for the commands that require dm-mod, if the tools can't get
the driver version.  It's not done for commands that don't require dm-mod.
This should clear up some problems people have had attempting to use lvm2
without rtfm'ing.

25b733809a Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.
