4059d2219c Recognise DRBD device part and handle it similar to MD devices.
The DRBD uses underlying device so code should prefer top
device if duplicate is found.

Patch also introduce
        dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.

See https://bugzilla.redhat.com/show_bug.cgi?id=530881
for full problem description.

68fac97a07 Add vg_is_resizeable() and cleanup references.
Clean up VG_RESIZEABLE flag by creating vg_is_resizeable().
Update comment - we no longer have ALLOW_RESIZEABLE.
Also use vg_is_exported() in one place missed by earlier patch.
Should be no functional change.

905240f91d Use vg_is_exported(vg) macro everywhere.
This patch is all just cleanup and no other patch depends on it.

04b2a4bdcf Add --dataalignmentoffset to pvcreate to shift start of aligned data area
Adds pe_align_offset to 'struct physical_volume'; is initialized with
set_pe_align_offset().  After pe_start is established pe_align_offset is
added to it.

1bd72d90a4 Add vg_reduce to metadata.c and metadata-exported.h
This function behaves a little bit different than vg_reduce_single, because
it allowes to remove even the latest pv. This has been done to be consistent
to lvm_vg_create, which creates an empty vg.

removed_pvs has been added to the volume_group struct. vg_reduce adds remove
pvs to this list to be able to commit the changes for the pvs in lvm_vg_comm
in liblvm2app.

Initialize removed_pvs list in format-specific volume_group constructors.
Ideally, we should have a base constructor here that initializes the general
non-format specific members of struct volume_group.  But until then, there
are multiple places to initialize these members.  Maybe a better patch would
be a base constructor patch for struct volume_group.  That is more work
though.

0b706ac672 Introduce link_lv_to_vg and unlink_lv_from_vg functions.
link_lv_to_vg and unlink_lv_from_vg are the only functions
for adding/removing logical volume from volume group.

Only these function should manipulate with vg->lvs list.

494b4cec7b Tidy format1 import LV function.
Later patch initializes lv->vg after the LV structure is prepared,
so pass through cmd context and do not use vg->cmd here.
Also move LV id calculation (which uses lv->vg too).

Also properly free memory pool if operation fails.

4b13d5a823 Fix snapshot segment import to not use duplicate segments & replace.
The snapshot segment (snapshotX) is created twice
during the text metadata segment processing.

This can cause temporary violation of max_lv count.

Simplify the code, snapshot segment is properly initialized
in init_snapshot_seg function now and do not need to be replaced
by vg_add_snapshot call.

The vg_add_snapshot() is now usefull only for adding new
snapshot and it shares the same initialization function.

The snapshot name is always generated, name paramater can be
removed from function call.

8e1d5615b4 Introduce memory pool per volume group.
Since now, all code reading volume group is responsible for releasing
the memory allocated by calling vg_release(vg).
(For simplicity of use, vg_releae can be called for vg == NULL,
the same logic like free(NULL)).

Also providing simple macro for unlocking & releasing in one step,
tools usualy uses this approach.

The global memory pool (cmd->mem) should be used only for global
physical volume operations.

This patch have to be applied with all subsequent patches to complete
memory pool per vg logic.

Using separate memory pool has quite bit memory saving impact when
using large VGs, this is mainly needed when we have to use
preallocated and locked memory (and should not overflow from that
memory space).

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).
