In RHEL4, nfs server:
nfs mount keeps hanging from nfs client. So I disabled NFS4 with the following line in /etc/sysconfig/nfs:
RPCNFSDARGS=’–no-nfs-version 4′
But when I try to mount nfs from either RHEL3 or RHEL5, both failed with hanging mount.
Fix for RHEL5 client:
In RHEL4 nfs server, re-enable NFS4 by commenting out the above line in /etc/sysconfig/nfs. In /etc/exports, use the following option instead: *(rw,insecure,no_subtree_check,fsid=0)
Then in RHEL5 client, do:
mount -t nfs4 nfs4_server_name:/ client_folder_name
