This patchset enhances lvm with replicator metadata construction.
This version contains changes from Prague discussion.
Replicated-dev has been changed to replicated
(kernel driver though is still replicated-dev).
Sitemode has been renamed to sitepolicy.
Size and Extents are not needed when site argument is given.
Updated logic for specifying vg for lvcreate command.
Not yet finished:
HA LVM usage for activation of replicator.
Removal of replicator devices could be better.
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 --replicated -L10M -n L1 my/rep
lvcreate --replicated -L20M -n L2 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
