[openstack-dev] [Cinder]Behavior when one cinder-volume service is down

Hi,

Let me see if i got this:
- running 3 (multiple) c-vols won't automatically give you failover
- each c-vol is "master" of a certain number of volumes
-- if the c-vol is "down" then those volumes cannot be managed by another
c-vol

What i'm trying to achieve is making sure ANY volume is managed
(manageable) by WHICHEVER c-vol is running (and gets the call first) - sort
of A/A - so this means i need to look into Pacemaker and virtual-ips, or i
should try first the "same name".

Thanks,

Eduard

PS. @Michal: Where are volumes physically in case of your driver? <-
similar to ceph, on a distributed object storage service (whose disks can
be anywhere even on the same compute host)
