I am searching for an I/O fencing method like SCSI(3) reservation.
Is there any method implemented yet for use with heartbeat to avoid
accidently mount multiple times the same file system from diffrent nodes?

Of course I could configure heartbeat not to mount twice and I could
use a quorum server to make that more reliable.

But that does not include safety against accidently twice mounted

For some reasons ocfs2 or g(p)fs are no option.
