Patch is inspired by Debian's extra patch.

- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- 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
- prints whole 'install' command during installation instead of less
  informative "Installing  $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets

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

This check-in enables the 'mirrored' log type.  It can be specified
by using the '--mirrorlog' option as follows:

234b12480e lvconvert --merge @tag support
Switch lvconvert's --merge code over to using process_each_lv().  Doing
so adds support for a single 'lvconvert --merge' to start merging
multiple LVs (which includes @tag expansion).

Add 'lvconvert --merge @tag' testing to test/t-snapshot-merge.sh

Adjust man/lvconvert.8.in to reflect these expanded capabilities.

The lvconvert.c implementation requires rereading the VG each iteration
of process_each_lv().  Otherwise a stale VG instance associated with
the LV passed to lvconvert_single_merge() would result in stale VG
metadata being written back out to disk.  This overwrote new metadata
that was written when a previous snapshot LV finished merging (via
lvconvert_poll).  This is only an issue when merging multiple LVs that
share the same VG (a single VG is typical for most LVM configurations on
system disks).

In the end this new support is very useful for performing a "system
rollback" that requires multiple snapshot LVs be merged to their
respective origin LV.

The yum-utils 'fs-snapshot' plugin tags all snapshot LVs that it creates
with a common 'snapshot_tag' that is unique to the yum transaction.
Rolling back a yum transaction, that created LVM snapshots with the tag
'yum_20100129133223', is as simple as:
  lvconvert --merge @yum_20100129133223

This is useful for when the snapshot is still active and merging hasn't

Report snapshot origin with merging snapshot as 'O' instead of 'o':

the snapshot will be hidden, 'O' enables a user to see that there is a
snapshot merging.

72e0743621 This patch adds the capability to split off a mirror legs.
It is pretty much the same as reducing the number of
mirror legs, but we just don't delete them afterwards.

The following command line interface is enforced:
  prompt> lvconvert --splitmirror <n> -n <name> <VG>/<LV>
where 'n' is the number of images to split off, and
where 'name' is the name of the newly split off logical volume.

If more than one leg is split off, a new mirror will be the
result.  The newly split off mirror will have a 'core' log.
Example:
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
  LV            Copy%  Devices
  lv            100.00 lv_mimage_0(0),lv_mimage_1(0),lv_mimage_2(0),lv_mimage_3(0)
  [lv_mimage_0]        /dev/sdb1(0)
  [lv_mimage_1]        /dev/sdc1(0)
  [lv_mimage_2]        /dev/sdd1(0)
  [lv_mimage_3]        /dev/sde1(0)
  [lv_mlog]            /dev/sdi1(0)
[root@bp-01 LVM2]# lvconvert --splitmirrors 2 --name split vg/lv /dev/sd[ce]1
  Logical volume lv converted.
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
  LV               Copy%  Devices
  lv               100.00 lv_mimage_0(0),lv_mimage_2(0)
  [lv_mimage_0]           /dev/sdb1(0)
  [lv_mimage_2]           /dev/sdd1(0)
  [lv_mlog]               /dev/sdi1(0)
  split            100.00 split_mimage_0(0),split_mimage_1(0)
  [split_mimage_0]        /dev/sde1(0)
  [split_mimage_1]        /dev/sdc1(0)

It can be seen that '--splitmirror <n>' is exactly the same
as '--mirrors -<n>' (note the minus sign), except there is the
additional notion to keep the image being detached from the
mirror instead of just throwing it away.

7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'

0ddb66efba Add --pvmetadatacopies as a synonym for --metadatacopies in various commands.
Going forward, we would like to allow users to specify the total
number of metadatacopies in a VG rather than on a per-PV basis.  In
order to facilitate that, introduce --pvmetadatacopes to replace
--metadatacopies everywhere.  We still allow --metadatacopies for
pv commands, but require --pvmetadatacopies for vg commands.
Eventually we will introduce --vgmetadatacopies.  Once we do that,
we should either deprecate --metadatacopies or make it a synonym based
on the command (pvmetadatacopies for pv commands, and vgmetadatacopies
for vg commands).  The latter option would likely just require a simple
'strncpy' check against cmd->command->name to qualify the merge_synonym
call.

Update nightly tests to cover the pvmetadatacopies synonym.

Note that this patch is the result of an eariler review comment for
the implicit pvcreate patches.  Should apply cleanly on top of the
implicit pvcreate patches (I applied after patch 10/10 in that series).

NOTE: This patch will require --pvmetadatacopies for vgconvert as
--metadatacopies is no longer accepted.

eb7c87e90d Refactor vgsplit - reorder _vgsplit_from and _vgsplit_to based on flag.
Slight functional change.  If we open the destination first, we cannot
know the 'fmt'.  In this case we use the default metadata type unless
the user has specified -M on the cmdline.  If not, in most cases this
is fine since we use the LVM2 default metadata type.  However, if the
user is specifying a non-default metadata type (e.g. lvm1) and the order
of the names is such that we have to open the destination (vg_to) first,
we have a problem.  So in this case, we require the use of -M and vgsplit
will fail with an error if not.  I've updated the man page to recommend
the usage of -M in this case.

0b502933c5 Introduce lvm2_install target.
Buildsystem support device-mapper only install,
but generic install tagret includes both dm+lvm2.

For distribution which uses separate install_device-mapper,
there is no way how to install lvm2 only
(so after installing lvm2 for packaging purposes
built system must remove installed device-mapper files).

Fix it by allowing lvm2_install target, similarily like
install_cluster for clvmd.

(install = install_device-mapper + install_lvm2)

8929ce6651 Add --dataalignment to pvcreate to specify alignment of data area. (mbroz)
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).

given in pvcreate options due to rounding and alignment effects.

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).

a6d4f21cdb minor updates to the lvcreate/lvconvert man pages.

Jonathan Earl Brassow
19583d115c This patch changes the arguments that specify the mirror
log type.  Previously, we had a '--corelog' argument that
would change the default type from 'disk' to 'core'.  I
think that creates too much confusion - especially when
doing conversions on mirrors.

The new argument '--log' takes either "disk" or "core"
as a parameter.  This could be expanded in the future
for additional logging types as well.

Examples:
# Creating a 2-way mirror
$> lvcreate -m1 ... # implicitly use default disk logging
$> lvcreate -m1 --log disk ... # explicit disk logging
$> lvcreate -m1 --log core ... # specify core logging
$> lvcreate -m1 --corelog ... # old way still works

# Conversion examples
$> lvconvert --log core ... # convert to core logging
$> lvconvert --log disk ... # convert to disk logging
$> lvconvert -mX --corelog ... # old way still works
$> lvconvert -mX ... # old way of converting to disk logging still works

Changes are reflected in the man pages.
