Replicator 100707

This patchset enhances lvm with replicator metadata construction. It 'should not' influence other commands.

Use case example:

# build remote devices
vgcreate vg_ny /dev/loop1
vgcreate vg_paris /dev/loop2

lvcreate -L10M -n L1 vg_ny
lvcreate -L10M -n L1 vg_paris
lvcreate -L20M -n L2 vg_ny
lvcreate -L20M -n L2 vg_paris

# build local replicator
vgcreate my /dev/loop0
lvcreate --replicator rep -L20M my

lvcreate --site Berlin --replicator my/rep
lvcreate --site NY --remotevg vg_ny --replicator my/rep lvcreate --site Paris --remotevg vg_paris --replicator my/rep

lvcreate --replicatordev -L10M -n L1 --replicator my/rep lvcreate --replicatordev -L20M -n L2 --replicator my/rep

lvcreate --replicator rep -L20M my || exit 1 lvcreate --replicatordev -L10M -n L1 --replicator my/rep

lvremove my/L1

Note: after removing 'L1' LV 'L1_rimage' and '_slog' devices are left in VG Ideally user should use own 'VG'
and for removal just run:

vgremove my

lvchange --site Berlin --replicator my/rep -ay
== lvchange --site Berlin my/L1 -ay
== lvchange --site Berlin my/rep -ay
