Mount: Structure needs cleaning

Hi,

First up - my knowledge of linux is pretty sparse - I've used it a few times before, so please be gentle!

I've had a neil poulton network space for some time now - it freaked out a while ago and I managed to rig it up to a Ubuntu liveCD via a SATA dock and rescue the files.

This has now happened again - the drive would not get out of a cycle and was not spinning properly. Bring out the dock and liveCD (this time Knoppix). All good. This time however as I eagerly copied files to another drive (a USB powered lacie rugged thing) and left it overnight i woke up to an error. I was copying around 500GB in a few diffferent chunks. The first error it reported was I think error 15? mount structure needs cleaning...

I then tried with a Ubuntu liveCD - same error. This is maybe where I made a bit of an error of my own. In an attempt to shake it out of it's stupor I 'stupidly' plugged it into windows and opened up the disk utility (sorry I'm generally mac based) and deleted in total 5 partitions (3x8mb, 1x250odd mb &

1x600mbish partition) This left the partition that I assumed contained all my files: a 920GB partition. Tried to look at it again on Linux & (both Knoppix & Ubuntu) and the error message had changed slightly. It now reads:
"Error mounting /dev/sdc2 at /media/ubuntu/e8b90eb2-8718-4964-939d-8a2b899b68bd: Command-line `mount -t "xfs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdc2" "/media/ubuntu/e8b90eb2-8718-4964-939d-8a2b899b68bd"' exited with non-zero exit status 32: mount: Structure needs cleaning"

This drive has all my audio and video stored on it! Any help to move me toward a solution would be much appreciated!

Thanks for your time...

Tom

To be clear, you've deleted partitions other than the partition of interest? I suppose that shouldn't effect things either way, but I'm not really sure what the disk utility might do. It might be worth checking whether 'file -s <device>' still identifies the partition as an XFS filesystem..?

Beyond that, I'd suggest to capture and post the logs of the failed mount and perhaps the output of 'xfs_repair -n <dev>.' This will attempt a dry-run (e.g., no modifications) check and repair of the filesystem.

Hey Brian,
Apologies! I'm pretty new to all this so you'll have to walk me through it if possible - how do I check the logs?

ok - so I worked out & tried the xfs_repair command:

Yes it's a NAS drive and so I assume had some kind of proprietary OS on the other partitions (this is where i might have messed up by deleting?!) I'm pretty sure that the drive in bold below (sdc2) is the one I'm after which is xfs...

Which means the filesystem tried to read the offset at 62GB and the underlying device failed it with EIO. That's not an XFS failure. What error is there in dmesg when you run that xfs_repair command?

This asks you to post the contents of /proc/partitions, which is what the kernel thinks are the partition sizes.

Ummm, exactly what are you trying to do with this drive/filesystem? What device did the drive come from in the first place?

"Input/Output Error" . Run the "dmesg" command immediately after this error, and see what it reports last (end of command output).

Most probably disk is badly damaged, dead or dying. It's advisable to try to create an image of the disk on another one, and work for this image, because this disk will probably die any time now. It's no use trying to repair a filesystem on a bad drive, which is the cause of the errors from the beginning.

If all you care is to get your files back, just try to mount the volume in read-only, non-recovery mode :

mount -o ro,norecovery /dev/sdc2 /tmp/mount

Then proceed by copying whatever you can get. Consider that any file that gives an error is lost.

The other option is Kroll Ontrack or similar services, of course.
