bad superblock

I‘ve netapp NFS server with /data3 as shared directory. I type the following command at Ubuntu Linux to mount the NFS server:

mount fs2:/data3 /nfs/
OR
mount 192.168.1.100:/data3 /nfs/

But I’m getting an error which read as follows:

mount: wrong fs type, bad option, bad superblock on fs2:/data3,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog – try
dmesg | tail or so

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?
