Any failover you're doing would need to be handled outside the
filesystem, of course; STONITH etc? I don't know that reading xfs
internals will be all that relevant.
But I suppose the details may help if you think it is an xfs-related

CXFS is and probably will be the only direct clustering mechanism for
xfs... it is still active, though as you note it is not (and probably
will never be?) open source.
block-layer failover should be as possible on xfs as any other
