[Ocfs2-users] Cluster setup

[Luis Freitas]

Is there any cluster NFS solution out there? (Two NFS servers sharing the same filesystem with distributed locking and failover capability)

The storage servers mount the shared disks and the reexport

ubuntu 6.06 is too old. If you are stuck on Ubuntu LTS, the
next version 7.10 should have all you want.
