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.

2aabcc1c1c Add devices/data_alignment_detection to lvm.conf.
Adds 'data_alignment_detection' config option to the devices section of
lvm.conf.  If your kernel provides topology information in sysfs (linux
>= 2.6.31) for the Physical Volume, the start of data area will be
aligned on a multiple of the ’minimum_io_size’ or ’optimal_io_size’
exposed in sysfs.

minimum_io_size is used if optimal_io_size is undefined (0).  If both
md_chunk_alignment and data_alignment_detection are enabled the result
of data_alignment_detection is used.

57b660356e Add devices/data_alignment_offset_detection to lvm.conf.
If the pvcreate --dataalignmentoffset option is not specified the start
of a PV's aligned data area will be shifted by the associated
'alignment_offset' exposed in sysfs (unless
devices/data_alignment_offset_detection is disabled in lvm.conf).

3d425215a8 Continue to make --units and --size consistent (in code and man pages):
Update units_to_bytes() to support (S)ectors: 500 bytes.
- 500 byte (S)ectors is of questionable value but it adds to consistency
  if a user happens to use --units S.  This seems better than an error.

Updated test/t-covercmd.sh to test --units [hS]

Document the units that can be displayed via --units uniformly.
- (p)etabytes and (e)xabytes were missing in pvs, vgs and lvs man pages.

Made lvreduce man page "... in units of megabytes." consistent (with the
lvextend and lvresize man pages).

01b988cfd8 Cleanup pvs, vgs, and lvs "-o" section in man pages (rhbz 500861).
http://bugzilla.redhat.com/show_bug.cgi?id=500861
- Update list of fields/columns for each command (a few missing).
- Update list order to match "-o help" output (easier to verify field list)
- Add "{pv|vg|lv}_all" description.
- Move "-o help" sentence above column/field list.

New sample man page for lvs (pvs and vgs are similar):
       -o, --options
              Comma-separated ordered list of columns.  Precede the list  with  ’+’  to  append  to  the
              default selection of columns instead of replacing it.

              Use  -o  lv_all to select all logical volume columns, and -o seg_all to select all logical
              segment columns.

              Use -o help to view the full list of columns available.

              Column names  include:  lv_uuid,  lv_name,  lv_attr,  lv_major,  lv_minor,  lv_read_ahead,
              lv_kernel_major,  lv_kernel_minor,  lv_kernel_read_ahead, lv_size, seg_count, origin, ori-
              gin_size, snap_percent, copy_percent, move_pv, convert_lv, lv_tags,  mirror_log,  modules,
              segtype,  stripes,  stripesize,  regionsize, chunksize, seg_start, seg_start_pe, seg_size,
              seg_tags, seg_pe_ranges, devices.

              With --segments, any "seg_" prefixes  are  optional;  otherwise  any  "lv_"  prefixes  are
              optional.  Columns mentioned in vgs (8) can also be chosen.

              The lv_attr bits are:

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).

e9f57f2beb Add pv_mda_size to 'pvs' and vg_mda_size to 'vgs'.
Reports the size of the smallest metadata area in a PV or a VG.
Useful to confirm pvcreate --metadatasize or pvmetadatasize setting in
/etc/lvm/lvm.conf file.

NOTE: Actual value in these fields will most always differ from that
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).
