3be9089cd3 Add 'vgscan --cache' functionality for consistency with 'pvscan --cache'.
Calling vgscan alone should reuse information from the lvmetad (if running).
The --cache option should initiate direct device scan and update lvmetad
appropriately (if running).

This is mainly for vgscan to behave consistently compared to pvscan.

34a45b0029 Fix warn message and update man page
Fix regression in man page. The chunk size is in kilobyte units on command line
input though in the source code we work with sector size unit
so make it clear in the man page.

Update chunksize for thin pool in man page - it's max value is 1024M == 1G.

Fix warning range message to show proper max value.

4fbde0143a Support rounding of percentage upward
We want to keep this logic -
when LV is extend - extend the LV by at least given amount,
when LV is reduced - reduce the LV by at most given amount.

So for this the rounding needs to be used.
Current logic which seems to satisfy give rule is to round up all
extent values for LV resize upward except for values with '-' sign
that are round downward.

This patch also fixes the problem when  lvextend --use-polices tried
to extend LV the by i.e. 20% - but the resulting 20% were smaller
the extent size thus before this patch no extension happened.

0c506d9a40 Support the ability to replace specific devices in a RAID array.
RAID is not like traditional LVM mirroring.  LVM mirroring required failed
devices to be removed or the logical volume would simply hang.  RAID arrays can
keep on running with failed devices.  In fact, for RAID types other than RAID1,
removing a device would mean substituting an error target or converting to a
lower level RAID (e.g. RAID6 -> RAID5, or RAID4/5 to RAID0).  Therefore, rather
than removing a failed device unconditionally and potentially allocating a
replacement, RAID allows the user to "replace" a device with a new one.  This
approach is a 1-step solution vs the current 2-step solution.

example> lvconvert --replace <dev_to_remove> vg/lv [possible_replacement_PVs]

'--replace' can be specified more than once.

example> lvconvert --replace /dev/sdb1 --replace /dev/sdc1 vg/lv

Any documentation less-detailed than Documentation/device-mapper is
dangerous for the non-trivial ctr lines.  And anyway, this should be in s4

a039e204e7 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.

dbb48de507 Add a new 'thin_pool' output field to 'lvs.
A gentle reminder that anyone relying on the output of reporting commands
like lvs in scripts must use -o to guarantee they get the fields they expect.

The default sequence of fields can change from release to release.
Equally, the 'attr' fields can have new values introduced and/or characters
appended to them.
