I use gfs2 quite a bit, but not nfs. Can I make a suggestion? Don't use gfs2 for this. You will have much better performance if you use an active/passive failover with a non-clustered FS. GFS2, like any cluster FS, needs to have the cluster handle locks which is always going to be slower (by a fair amount) than traditional internal FS locking. The common NFS HA cluster setup is to have the cluster promote/connect the backing storage (drbd/iscsi), mount the FS, start nfs and then take a floating IP address. GFS2 is an excellent FS for situations where it is needed, and should be avoided anywhere possible. :) -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
