[Ocfs2-users] HA-OCFS2?

[Sunil Mushran]

cfs != storage

You need to get a highly available storage that is concurrently accessible
from multiple nodes.

ocfs2 will allow multiple nodes to concurrently access the same storage.
With posix semantics.
If a node dies, the remaining nodes will pause to recover and then continue
functioning. The
dead node can then restart and rejoin the cluster.
