Any reason why you're not using the O2CB cluster stack for OCFS2? I have no personal experience using non-Oracle cluster stacks with OCFS2.
Pacemaker manages o2cb
Can anyone comment on their experience with gfs and/or ocfs2 and reliability?
I'm using ocfs2 to store xen configs, and iso images for xen vm's, so performance really isn't a consideration while reliability is.
OCFS2/O2CB form the basis of the cluster filesystem and stack for Oracle VM, which provides both reliability and performance. Check how recent your ocfs2-tools are, because mkfs.ocfs2 now has a -T vmstore option which is optimised for storing Xen-like virtual disk images alongside small configuration files. It also enables reflink support (for copy-on-write clones) and inode packing.
I've read about that but don't have a platform to test it on yet. James
