Hello Joel, Thanks for your reply. Could you please clarify for me these issues
First scenario: I'd like to create RAID5 with OCFS2 partition on my primary cluster node and then export this partition with MySQL data storage over NFS to other two cluster nodes. If each cluster node is running separate MySQL server, then will each MySQL server be able to access and use simultaneously that OCFS2 shared and exported over NFS data storage? Second scenario: OCFS2 partition is created on DRBD block device between primary node1 and secondary node2. Can I achieve the same functionality for MySQL servers as in the First scenario, if I export over NFS /dev/drbd0 from the primary node1 to other participating nodes in the cluster?

I say ocfs2. Of course, I work on it, so I would say that, wouldn't I? ;-) Seriously, ocfs2 is very robust and tested, especially on the enterprise distributions. I want to be clear, both gfs2 and ocfs2 are shared-disk filesystems. They are not "distributed" filesystems, in that they require the shared disk and are not network filesystems. You may already know this, but I just wanted to be clear. Joel -- "Every new beginning comes from some other beginning's end."
