[Ocfs2-users] Prototyping OCFS

[Elliott Perrin]

OCFS2 does not do replication, it is a clustered file system. You need to be either 

a) using shared storage (SAN) and mounting the same LUN on each host
b) using DRBD to replicate data between the two hosts if you do not have backing shared storage 

OCFS2 is definitely stable.
