I recently installed NFS server v4 on my HP Linux server. However, I’m not able to mount it from Linux nfs4 client using the following command:

mount.nfs4 server2:/data /data

I’m getting the following error:

mount.nfs4: mounting server2:/data failed, reason given by server:
No such file or directory

How do I fix this problem?
