Hello everybody and excuse me in advance for the apparently dumb
question, but I havent found any answer yet!
I'd want to create a gfs2 filesystem.
for doing this I attached to my nodes a shared SCSI lun (shared disk in
vmware).
For commodity I have created a LVM volume group on it and a volu
so, then the "under Pacemaker" part is irrelevant - since
Pacemaker would have no interaction with it.

Hello Ryan,
glusterfs is not the same as drdb. We use it to replicate data from
one node to the other and use corosync/pacemaker to do guaranty that
one node is active.
I assume that you can never directly touch the R2, because there is a
filesystem on R1 that is replicated to R2?
Regards,
Richa
but node A and B have control of R1 (active-active).

Hello Ryan,
If you want to have shared storage by two nodes via a SAN, you should
look for a clustered filesystem like gfs2 or ocfs2.
We use shared storage by replication via glusterfs (www.gluster.org).
The backend storage can be on a LUN or on a local disk.
If one node fails, the standby has a r
Hi,
My testing two node (openais and corosync) cluster is up and running (RHEL
v5.5). Now I'd like to create LVM disk storage for the cluster for failover.
The cluster is attached to an EMC Symmetrix SAN. The same LUNs from the EMC
Symmetrix can be seen on both nodes.
I was thinking to use DRB
