Re: fsck error read of OLT Failed

hi,

make it sure that it is a vxfs file system.
try
fsck -F vxfs -o full /dev/vg00/rcdb_test

"fsck_vxfs does not search for all possible alternate super blocks" is a know bug and is documented in JAGaa53168.

To get a fix, please contact your local HP Support Center.

Re: fsck error read of OLT Failed

Hi Luk,

seeing that fsck error I have a nightmare!!!
I had the same error few weeks ago.

In my instance the problem was a LUN belongs to more volume groups on more systems due to a bad LUN configuration on XP1024.
Then I got that fsck error when I created a filesystem and mounted it. In particular on mount operation I got something like 'filesystem corrupted' and I was saying: 'Why??? I have just created it!!!'

Then I ask you: Is /dev/vg00/rcdb_test a filesystem created on a LUN (in a SAN area) or on internal disk of your HP-UX system?

If it is on a LUN then I would suggest you to check LUN configuration.

Hope this helps you.

Best regards,
Fabio

Re: fsck error read of OLT Failed

It as an LV on a local disk (vg00)
I recreated the lv and restored the data
