XFS_REPAIR on LVM partition

[Rafael Weingartner <rafaelweingartner@xxxxxxxxx>]

Hi folks, 

I am having some troubles with a XFS over one LVM partition. After an unexpected reboot, I am getting the following message when I try to mount it:

mount: Structure needs cleaning

I tried "sudo xfs_check /dev/mapper/volume". Sadly, I got the message:

xfs_check: cannot init perag data (117)

ERROR: The filesystem has valuable metadata changes in a log which needs to

be replayed.  Mount the filesystem to replay the log, and unmount it before

re-running xfs_check.  If you are unable to mount the filesystem, then use

the xfs_repair -L option to destroy the log and attempt a repair.

Note that destroying the log may cause corruption -- please attempt a mount

of the filesystem before doing this

So, I tried:

xfs_repair -L 

The command is running for over 3 hours and still just dots on my screen, I have no idea of what is happening. Any ideas how I can get it to work again? Or at least some work around that would enable me to extract the data that it contains.

The server is a Ubuntu server 12.04.

The XFS version is: xfs_info version 3.1.7

If you need I can provide you with more info.

Thanks,
