911d6efa51 toollib: refactor extract_vgname
Split internals of extract_vgname into _extract_vgname.
This common code will be used for other similar function.

Reuse skip_dev_dir() instead of less mature coded to skip
device dir.

Instead of duplicating full vg/lv name - allocate string
only vg portion of lv name.

45f57477f4 cleanup: Use segtype.h definitions of segment type names wherever possible
We are not using already defined segement type names where we could.

There is a lot of other places in device-mapper and LVM2 we have those
hardcoded so we should better finally have a common interface in
libdevmapper to avoid this.

a8aee7dba2 activate: update lv_check_not_in_use: API
Use of lv_info() internally in lv_check_not_in_use(),
so it always could use with_open_count properly.

Skip sysfs() testing in open_count == 0 case.

Accept just 'lv' pointer like other functions.

The function has 'built-in' lv_is_active_locally check,
which however is not what we need to check in many place.
For now at least remotely active snapshot merge is
detected and for this case merge on next activation is scheduled.

c96665e6a8 lvconvert: reoder old snapshot merge
Move check for snapshot-merge support before archiving.

Split code on 2 paths - with merge_on_activate
using vg_write & vg_commit
and lv_update_reload call for instant merging.

Move printing after backup.

13c07c685a thin and cache: improve conversion validation
More validations before any thin or cache related conversion begins.

We allow to use and stack:

pool data: cache or raid
pool metadata: raid

pool:  linear, striped
cache: linear, striped, raid
thin(extorig): linear, origin, cow, virtual, thin

736f40134b mirror: extend adjusted_mirror_region_size API
We use adjusted_mirror_region_size() in two different contexts.

Either on command line -
 here we do want to inform user about reduction of size.

Or in pvmove activation context -
 here we should only use 'verbose' info.

392bb6f46e fix: regression for recent persistent commit
Do not let fly metadata with just 'minor' set
(since they would not be readable on older version)

Be permissive with invalid major/minor number and
just report them as problem, but allow to use
such metadata with default major:minor.

702b648215 cleanup: lvchange remove some extra code.
We do not need to restore LV content on error path - since
for reactivation we always use  ondisk/commited metadata,
so passed data are never used.

Drop some unneded extra message, since the called function
repeated logs same info.

f09f85d027 tools: common handling of --persistent option
Move common code for reading and processing
of --persistent arguments for lvcreate and lvchange
into lvmcmdline.

Reuse validate_major_minor() routine for validation.

Don't blindly activate LVs after change in cluster
and instead only local reactivation is supported.
(we have now many limited targets now).

Dropping 'sigint_caught()' handling, since
prompt() is resolving this case itself.

98414ca7dd vgchange: support clustered conversion for active lv
If we want to support conversion of VG to clustered type,
we currently need to relock active LV to get proper DLM lock.

So add extra loop after change of VG clustered attribute
to exlusively activate all active top level LVs.

When doing change -cy -> -cn  we should validate LVs are not
active on other cluster nodes - we could be sure about this only
when with local exclusive activation - for other types
we require user to deactivate volumes first.

As a workaround for this limitation there is always
locking_type = 0 which amongs other skip the detection
of active LVs.

FIXME:
 clvmd should handle looks for cluster locking type all the time.

9d57aa9a0f cache-pool: Fix specification of cachemode when converting to cache-pool

b87a7683e2 clean-up: better macro usage
Use 'lv_is_mirror' instead of 'lv_is_mirrored && !lv_is_raid' - both

used.

979be63f25 mirrors: Fix checks for mirror/raid/pvmove LVs.
Try to enforce consistent macro usage along these lines:

lv_is_mirror - mirror that uses the original dm-raid1 implementation
               (segment type "mirror")
lv_is_mirror_type - also includes internal mirror image and log LVs

lv_is_raid - raid volume that uses the new dm-raid implementation
             (segment type "raid")
lv_is_raid_type - also includes internal raid image / log / metadata LVs

lv_is_mirrored - LV is mirrored using either kernel implementation
                 (excludes non-mirror modes like raid5 etc.)

lv_is_pvmove - internal pvmove volume

47ff145e08 debug: turn message into debug
This message should be printed only for activation commands,
however since the handling of this flag is not correct

do now just a minor change and switch message into log_debug
(so it's not printed i.e. with every  'lvs -v')

84860fd54f lv: remove lv_type_name fn
The lv_type_name function is remnant from old code that reported
only single string for the LV type. LV types are now reported
in a more extended way as keyword list that describe the type
precisely (using lv_layout_and_type fn).

The lv_type_name was used in some error messages to display the
type of the LV so just reinstate the old messages back referencing
the type directly with a string - this is enough for error messages.
They don't need to display the LV type as precisely as it's used
on lvs output (which is optimized for selection anyway).
