(for example when CLVMD_CMD_LOCK_VG for is called during vgscan).
If clvmd calls LV lock, it calls
/* clean the pool for another command */
dm_pool_empty(cmd->mem);
to clean up memory pool after command.
Unfortunately, do_refresh_cache() do not call this
and because during it operation it allocates some memory,
the pool increases.
Also do_refresh_cache should use lvm_lock
(it manipulates with lvm internal data).
The same applies for lvm_backup command.

if rlocn not defined (there is no metadata area).
In most cases it fails in validate_name(),
unfortunately there are situatuions, when
validate_name is ok and later code fails with
checksum error.
Reproducer:
# dd if=/dev/zero of=/dev/loop0
# pvcreate --metadatasize 637k /dev/loop0
Physical volume "/dev/loop0" successfully created
# pvs /dev/loop0

Using argv[] list in exec_cmd() to allow more params for external commands.
Fsadm does not allow checking mounted filesystem.
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
Fsadm improved handling of command line options.
New structure lvm (used as an alias to cmd_context), new type definition lvm_t
for the lvm handle. Added functions lvm_create, lvm_destroy and
lvm_reload_config using the new handle.
Modified test/api/test.c:
Use new lvm.h header file and lvm_t handle.
Removed lib/lvm2.h
Author: Thomas Woerner <twoerner@redhat.com>
This patch is not fully tested and leaves some related bugs unfixed.
Intended behaviour of the code now:
pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.
In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.
Currently, the field storing the size of the data area in the PV label
header always holds 0. As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.
This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.
(There should be no user visible change in output.)
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().
pvcreate $DEV
vgcreate -s 1k vg_test $DEV
lvcreate -l 1 -n lv1 vg_test
..
/dev/vg_test/lv1: write failed after 1024 of 4096 at 0: No space left on device
Just check for maximum write size in set_lv.
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.
