Re: [HPDD-discuss] ldiskfs corruption
That appears to have worked - thank you very much! I have the e2fsck and e2image output.
I can post the former to the JIRA but the image is too big to upload to the JIRA as an
attachment. Please email me if you want the image and I’ll send it to you via our file
transfer service (I don’t have a good way to post it publicly).

Hi Darby,
This looks similar LU-3542, I think it would be useful to get an image
of the filesystem for analysis as we only have one image and it's not as
damaged as yours. Can you do:
e2image -Q /dev/OSTnnnn OSTnnnn.qcow
bzip2 -9 OSTnnnn.qcow
After you take the image, you can clean up the file system by creating a
debugfs script to unlink the files manually, it should look something like:
unlink /O/0/d4/3102500
unlink /O/0/d2/3102690
...(1032 entries)
You can parse it out from the 'has deleted/unused inode' messages in
e2fsck. Then it's a matter of doing debugfs -w -f <script> <dev>.
HTH,
Kit
