If you are going to access the same data file two or more servers you must use some type of cluster filesystem. You do not need to run the full cluster suite to use gfs. I use GFS to share files between two servers. I do not have the cluster suite installed, that is for application failover not file sharing.

The reason being that everything using a shared file system like this must be able to communicate in order to negotiate locking. If there was no such communication, you'd have the possibility of node1 and node2 trying to write the same block at the same time, and thus causing inconsistent data. Red Hat Cluster Suite manages this communication to ensure everything is copasetic. Shared storage + GFS is not a replacement for NFS.

I have SAN connected to several computers by fibre, and it appears that GFS is the way to go as opposed to use an NFS server. Do I really need to set up all the other aspects of a Redhat cluster to get GFS to work? There doesn't seem to be a good HOW-TO of this anywhere, and the RedHat docs are not as helpful as I would have liked. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
