gridstor + cluster linux ocfs2

I want to use GridStor technology, but I don’t want to use NFS or SMB. I am looking for a solution where I can share the mount path between two Media Agents (MA). If MA1 is offline, MA2 should still be able to perform backup and restoration. I have researched this and am considering deploying a Linux cluster with Pacemaker, Corosync, and OCFS2. My question is whether OCFS2 is supported by Commvault.
