Hello, We have a GlusterFS configuration with mirrored nodes on the master side geo-replicating to mirrored nodes on the secondary side.
When geo-replication is initially created it seems to automatically add all the mirrored nodes on the master side as geo-replication master nodes, which is fine. My first question is, if we add a new master side node how can we add it as a geo-replication master? This doesn't seem to happen automatically, according to the output of "gluster volume geo-replication gvol0 secondary::gvol0 status". If we use the normal "gluster volume geo-replication gvol0 secondary::slave-vol create push-pem force" it says that the secondary side volume is not empty, which is true because we're adding a master node to the existing geo-replication. My second question is whether we can geo-replicate to multiple nodes on the secondary side? Ideally we would normally have something like: master A -> secondary A master B -> secondary B master C -> secondary C so that any master or secondary node could go offline but geo-replication would keep working. Thank you very much in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782
