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?
NFS client needs portmap service, simply install nfs-comman package as follows to fix this problem:
$ sudo apt-get install nfs-common
Make sure portmap service is running:
sudo service portmap status
Sample outputs:
portmap start/running, process 4193
If not just start it:
$ sudo service portmap start
One installed you can see all shared NFS directories as follows:
showmount -e fs2
Sample outputs:
Export list for fs2:
/Sales
/Web
/Accounting
/Recordings
/Public
/Network Recycle Bin 1
/Music
/Download
/Games
/Family
Simply run mount command again:
$ sudo mkdir /nfs
$ sudo mount fs2:/data3 /nfs/
$ ls /nfs
