Linux: NFS4 mount Error reason given by server: No such file or directory

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?

Q. How can I Recover a bad superblock from a corrupted ext3 partition to get back my data? I’m getting following error:

/dev/sda2: Input/output error
mount: /dev/sda2: can’t read superblock

How do I fix this error?
