Hi there,

I am trying to mount a device (/dev/sda1) with ocfs and I am facing a few issues that seem to be pointing to a bad/corrupted header/super block.

Code:
sbin]# mount -t ocfs /dev/sda1 /u02/oradata/orcl/
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       or too many mounted file systems
Code:
sbin]# /sbin/fsck.ocfs /dev/sda1
/sbin/fsck.ocfs 1.1.5-PROD1 Fri May 20 10:58:55 PDT 2005 (build 17eb3d6fd0f7853771a0440c086aab8f)
/dev/sda1: bad signature in super block
Is it possible, with ocfs to recover a backup super block, or edit the mount_point value? There is a ton of doc available on to perform such operation with ocfs2 but I cannot find anything for ocfs.

Look at the mount_point value below...

Any help will be greatly appreciated
Thanks
