Re: [Jfs-discussion] fsck fails

[Barry A. <ba...@us...>]

Use the JFS utility xpeek to display the primary and secondary superblocks,
capture the output to a file, and send it to me.  We'll check to see if
they can
be repaired.

To display the superblocks, enter:

xpeek <device name>
> su  (to display primary superblock)
x  (to exit su display)
> s2p  (to display secondary superblock)
x  (to exit s2p display)
q  (to quit)

Note that a menu of available xpeek commands can be displayed via the
h command at the > prompt.

Thanks.

Subject:    [Jfs-discussion] fsck fails



I am using version 1.0.15 of jfs along with kernel 2.4.17 and LVM 1.0.3.

Due to a mistake, I ran into a problem with LVM and I had to recover
everything. For most of my stuff, everything went fine and I am up and
running. However, I still have a jfs file system which refuses to pass
the fsck test.

Here is the output from the fsck.jfs command:

------------- BEGIN -------------------
[root@einstein /]# fsck.jfs /dev/datavg/home
fsck.jfs version 1.0.15, 15-Feb-2002

The superblock does not describe a correct jfs file system.

If device /dev/datavg/home is valid and contains a jfs file system,
then both the primary and secondary superblocks are corrupt
and cannot be repaired, and fsck cannot continue.

Otherwise, make sure the entered device /dev/datavg/home is correct.
--------------- END -------------------------

My question: Is there anything I can try in order to recover the
filesystem or partial informations from it?
