438e0050df config: add silent mode
Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.

When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]

Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.

cd8ea8b437 activate: skip manual activation for --sysinit -aay
When --sysinit -a ay is used with vg/lvchange and lvmetad is up and running,
we should skip manual activation as that would be a useless step - all volumes
are autoactivated once all the PVs for a VG are present.

If lvmetad is not active at the time of the vgchange --sysinit -a ay
call, the activation proceeds in standard 'manual' way.

This way, we can still have vg/lvchange --sysinit -a ay called
unconditionally in system initialization scripts no matter if lvmetad
is used or not.

2729720fd3 args: add --activate synonym for --available arg
We're refererring to 'activation' all over the code and we're talking
about 'LVs being activated' all the time so let's use 'activation/activate'
everywhere for clarity and consistency (still providing the old
'available' keyword as a synonym for backward compatibility with
existing environments).

0a9f894ff0 Initial support for lvconvert for thin pool volumes.
Support has many limitations and lots of FIXMEs inside,
however it makes initial task when user creates a separate LV for
thin pool data and thin metadata already usable, so let's enable
it for testing.

Easiest API:

lvconvert --chunksize XX --thinpool data_lv  metadata_lv

More functionality extensions will follow up.

TODO: Code needs some rework since a lot of same code is getting copied.

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.

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

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.

6d04311efa Add the ability to split an image from the mirror and track changes.
~> lvconvert --splitmirrors 1 --trackchanges vg/lv
The '--trackchanges' option allows a user the ability to use an image of
a RAID1 array for the purposes of temporary read-only access.  The image
can be merged back into the array at a later time and only the blocks that
have changed in the array since the split will be resync'ed.  This
operation can be thought of as a partial split.  The image is never completely
extracted from the array, in that the array reserves the position the device
occupied and tracks the differences between the array and the split image via
a bitmap.  The image itself is rendered read-only and the name (<LV>_rimage_*)
cannot be changed.  The user can complete the split (permanently splitting the
image from the array) by re-issuing the 'lvconvert' command without the
'--trackchanges' argument and specifying the '--name' argument.
	~> lvconvert --splitmirrors 1 --name my_split vg/lv
Merging the tracked image back into the array is done with the '--merge'
option (included in a follow-on patch).
	~> lvconvert --merge vg/lv_rimage_<n>

The internal mechanics of this are relatively simple.  The 'raid' device-
mapper target allows for the specification of an empty slot in an array
via '- -'.  This is what will be used if a partial activation of an array
is ever required.  (It would also be possible to use 'error' targets in
place of the '- -'.)  If a RAID image is found to be both read-only and
visible, then it is considered separate from the array and '- -' is used
to hold it's position in the array.  So, all that needs to be done to
temporarily split an image from the array /and/ cause the kernel target's
bitmap to track (aka "mark") changes made is to make the specified image
visible and read-only.  To merge the device back into the array, the image
needs to be returned to the read/write state of the top-level LV and made
invisible.

880507498a Add --addnodeonresume, --addnodeoncreate
Add new function dm_task_set_add_node() to select between 2 types
of node creation in device directory.

DM_ADD_NODE_ON_RESUME is now default and ensures node is created on
resume. Old original behavior is accessible with DM_ADD_NODE_ON_CREATE.
In this case node would be created during dmsetup create --notable.

For the user 2 new options for dmsetup create are added:
[{--addnodeonresume | --addnodeoncreate }]

Properly working node creation on resume is needed for proper operation
stacking and ability to correctly check in which state the device should
after whole udev transation.

Result of trying to merge a snapshot using a kernel that doesn't have
the snapshot-merge target:

Before:
# lvconvert --merge vg/snap
  Can't expand LV lv: snapshot target support missing from kernel?
  Failed to suspend origin lv

After:
# lvconvert --merge vg/snap
  Can't process LV lv: snapshot-merge target support missing from kernel?
  Failed to suspend origin lv
  Unable to merge LV "snap" into it's origin.

bc963e745c Define vgmetadatacopies in vgchange man page.
This patch adds a vgmetadatacopies parameter for metadata balancing.
This parameter provides a simple way for users to create a policy for
placing metadata on PVs automatically by LVM.  The behavior is implemented
inside LVM by managing the 'ignore' mda bits.  We chose the name
'vgmetadatacopies' as this is a natural extension to the existing parameter
'pvmetadatacopies' / 'metadatacopies' in pvcreate.

This is a first step at VG parameter based metadata balancing.  Most users
will probably want to state that they want a certain number of PVs to contain
metadata, and they may be less concerned about a specific number of metadata
copies in the volume group.  However, for default values (pvmetadatacopies
is 1 by default), the number of metadatacopies in the volume group, and the
number of PVs with metadata are the same.  In the future we could add
vgmetadatacopiespvs to define more specifically the number of pvs in the
VG that contain metadata, but for now we start with this parameter.

Another possible future extension would be to define a specific pv tag
to mark the set of PVs that should be used for metadata balancing.  This
tag based approach could be used in conjunction with 'vgmetadatacopies'.

- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols
