Hi, Richard No, R2 side is read only and you can't mount it as a file system. Only when R1 and R2 in split mode, you can mount the file systems on R2 side as read/write. If needed the data, you need a BCV copy and mount the file systems for testing, backup, etc. In my test case, I don't need R2 and BCV. My R1 disks are already configured RAID 10 mode inside EMC's Symmetrix.

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, Richard > Thanks for the reply, Richard > >I went to the site (gluster.org).
