Linux NFS Mount: wrong fs type, bad option, bad superblock on fs2:/data3 Error And Solution

Posted on in Categories , , last updated June 12, 2010

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/
mount /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?

Linux / UNIX: Cannot Preserve Ownership Error when Files are Moved or Copied

Q. I’m using CentOS Linux. I’m getting an error – Cannot Preserve Ownership, when I try to copy files from Linux ext3 to FAT32 or files moved to an NFS NAS server mount point. How do I fix this error and copy / move files?

A. Generally you use command like cp or my to copy file. While copying a file these command try to copy file attributes such as ACL information or group access information etc. FAT32 and NFS mount mount cannot support all sort of attributes and these commands cannot differentiate between a filesystem that doesn’t support ACL and Linux file system permission.

All your files will be copied or moved without ACL and permissions. You can ignore this error and files should be copied / moved successfully.
