Or not use ocfs2 or any cluster filesystem, the only node that needs to have mounted the filesystems is the active one
If you try to mount a non cluster filesystem in another node while is mounted in a first one, the other node should answer 'partition used' or something similar ( prevents corruption )
when switching from nodes, as part of the automatic process, one node should umount and the other mount ( may be fsck first )
