Re: [Linux-cluster] Clusterng with GFS



You should not be unmounting the GFS anywhere.  GFS should be mounted everywhere.  With proper fencing (which is a MUST, no avoiding it) GFS can recover from losing a node with no downtime.  Then you just need to have the appropriate daemons and cleanup scripts running (usually from rgmanager).

If you want to failover a normal volume (another way to do this), just use XFS, reiserfs, or ext3.

Hello

I am trying to implement a failover cluster with shared storage concept (Postgresql Database 7.4).
RHEL AS 4.0 + RHCS + GFS

I am having two gfs volumes which gets mounted by cluster when any of the nodes in
cluster takes control. The volumes are getting mounted by the cluster whenever a node takes
control, but not getting unmounted when the node leaves the cluster. Especially when primary
node takes control, the volumes mounted on the secondary node (Node which gives control to the
primary node) is not getting unmounted. Anybody plz help me to solve this issue. Thanks for the help in advance
