2815870302 Fix pvs segfault when run with orphan PV and vg_mda_size or vg_mda_free fields 
We display '0' for these fields now in this case.  Ideally these values are
undefined for an orphan PV but today there is no way to specify undefined
with display functions such as _size64_disp().

6d1b3b5385 Calculate mirror log size instead of hardcoding 1 extent size. 
It fails for 1k PE now.

Patch adds log_region_size into allocation habdle struct
and use it in _alloc_parallel_area() for proper log size calculation
instead of hardcoded 1 extent - which can fail.

Reproducer for incorrect log size calculation:
        DEV=/dev/sd[bcd]

        pvcreate $DEV
        vgcreate -s 1k vg_test $DEV
        lvcreate -m1 -L 12M -n mirr vg_test

https://bugzilla.redhat.com/show_bug.cgi?id=477040

The log size calculation is mostly copied from kernel code.

0c8bdaf33c Fail add tree node when requested major/minor is used. 
Check for major/minor collision is added in _add_dev_to_dtree()
where we already read info by uuid,
so in the case of requesting major/minor it queries device-mapper
by major/minor for device availability.

da52655315 Fix "lvremove -f vgname" when vgname contains snapshots. 
Prior to this patch, "lvremove -f vgname" would fail if vgname contained
one or more snapshot LVs.  Now this passes, but has a side-effect.
If you issue "lvremove vgname" where vgname contains one or more snaps,
you will get an extra "y/n" prompt to remove the same snapshot.
Example:
$ lvs
  LV     VG     Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  lvsnap vgtest swi-a- 16.00M lvtest   0.05
  lvtest vgtest owi-a- 64.00M
$ lvremove vgtest
Do you really want to remove active logical volume "lvsnap"? [y/n]: n
  Logical volume "lvsnap" not removed
Do you really want to remove active logical volume "lvsnap"? [y/n]: n
  Logical volume "lvsnap" not removed
  Command failed with status code 5.

Fixing this will most likely require modification of the iterator
function, process_each_lvs_in_vg() to iterate over snaps in some
cases (e.g. lvs, vgdisplay -v) but not in others (lvremove).

ffc4a05bda Fix snapshot monitoring library to not cancel monitoring invalid snapshot. 
snapshot DSO unregistered itself when snapshot changed state to invalid.

This can cause a race (and several timeouts), when for example another snapshot
is added and in the middle of operation (suspend/resume) the monitoring thread
unregister itself.

Fix it by keeping the snapshot monitored after invalidation - just reset
threshold to not really print any messages to syslog.

The "status" field is treated as it ever has been, unknown flags there are
treated as fatal metadata errors. However, in the "flags" field, any unknown
flags will be ignored and silently dropped. This improves
backward-compatibility possibilities. (Any versions without support for this
new "flag" field will drop the field altogether, which is same as ignoring all
the flags there.)

3a30d1db20 Fix return values for reporting commands when run with no PVs, LVs, or VGs. 
The new error checking code caught some commands that were returning '0' as
an exit status for success.  This is incorrect and resulted in a benign error
message displayed (see below).  As of today, all commands should return a
value defined in lib/commands/errors.h (1-5).  This results in an exit code of
0 on success, or > 0 on failure (as stated in the lvm.8 man page).

Before change:
1. Make sure no PVs are on the system
2. Run 'pvs'
  Command failed with status code 0.

After change:
<no output>

746e7dc42e The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

eec663aa3b Fix vgsplit to only move hidden 'snapshotN' LVs when necessary. 
This bug has been around for a long time as far as I can tell.
Without this fix, a vgsplit would unconditionally move the
'hidden/internal' snapshot LVs, and result in corrupted metadata
in the following case:
vg1: contains lv1, lv1snap, both on pvset1
vg1: contains lv2, on pvset2

"vgsplit vg1 vg2 pvset2"
would result in "snapshot0" hidden LV being moved to vg2, and
the origin and cow being left in vg1.  The tools detect the
corruption in vg2, but not in vg1.

cbfbc6766e Fix vgsplit locking and remove unneeded error messages when split into new VG. 
When vg_lock_and_read() calls were added, they were done so incorrectly for
the destination VG (vg_to).  This resulted in the VG lock not obtained when
a new VG was the destination (vg_lock_and_read() would fail in the vg_read()
clause, which would then release the lock before returning NULL), and could
result in corrupted destination VG.

The fix was to put back the original lock_vol() and vg_read() calls for 'vg_to'.
The failure of vg_read() indicates "vg does not exist", and we key off that
to determine whether we are dealing with a new or existing VG as the
destination.

The first two error messages were also the result of the incorrect
vg_lock_and_read() calls:
  Volume group "new" not found
  cluster request failed: Invalid argument
  New volume group "new" successfully split from "vg"
