[HPADM] fsck -y -o full fails on a vxfs ...

Hello admins:

I have an HP B2000 running HP-UX 11.0 with the Sep 2002 Quality Pack
applied.

I had enabled a file system swap of a GB on one of the filesystems (/sr)
which is also mounted on /sr
   The /etc/fstab entry is
       /dev/vg01/lvol4 /sr vxfs delaylog 0 2

After changing a kernel parameter (dbc_min_pct/dbc_max_pct),
and rebooting, this filesystem wouldn't mount.

(I have previously rebooted this configuration fine).

I couldn't run fsck until I commented the swapfs type for /dev/vg01/lvol4
After doing so:

Running
   fsck -F vxfs /dev/vg01/lvol4
gives me:
    vxfs fsck: file system had I/O error(s) on meta-data
    log replay in progress
    full file system check required, exiting ...

Running
   fsck -F vxfs -o full /dev/vg01/lvol4
gives me:
   vxfs fsck: file system had I/O error(s) on meta-data
   log replay in progress
   pass 0 - checking structural files
   pass 1 - checking inode sanity and blocks
   vxfs fsck: fsck read failure bno = 2097652, off = 0, len = 8192

Doing
   fsck -F vxfs -o full,nolog /dev/vg01/lvol4
gives the same error.

Is the data on /sr gone ? Is there anyway to salvage whatever I can on /sr ?

Any help is appreciated.

Thank you
Subu
