Hello Everyone,
I want to restore the vxfs filesystem superblock in hpux11.11 .Please let me know the path of the superblock in 11.11


Thanks

Shalom,

fsck fixes these problems.

If that does not work:
newfs the file system and restore the thing from backup.

Hi Vee,

You May try fsck with full option as Steven said

#fsck -F vxfs -o full /dev/vgname/lvolname

Fsck normally try to recover the superblock from the auxillary one if the primary superblock is corrupted.


Not sure if some one could do it with fsdb command

Shalom again,

As noted:

fsck -F vxfs -o full /dev/vgname/lvolname

or its newfs time. Hope you have a backup.

Hi Vee,

You can see the backup super-blocks in /etc/sbtab file. Hope, it may help you.

Otherwise, as Steven said, do newfs followed by the restore of data.

Thanks

> fsck is not working.

Is it reporting a bad block or errno 5 (I/O error)? If so, fsck cannot fix the problem nor can the alternate superblocks. fsck fixes structural information for VxFS but it cannot fix bad spots on the disk. Look at syslog to see if disk errors are being logged.
