Can't read my XFS

I have 2 raid5 arrays that are tied together using LVM. and XFS, so both raids were mounted as /data.

Here is my fstab entry:
/dev/mapper/VolumeGroup01-DataVolume /data           xfs     noatime         0       2

I had problems rebuilding the raid so 3-ware sent me a scritp and it repaired the raid, but when I booted into the OS (debian) I was able to browse to /data and do an ls. I could see the directory contents and all seemd fine. I then did an ls a few seconds later and recieved:
ls: reading directory .: Input/output error


I looked in the dmesg logs and found:
xfs_force_shutdown(dm-0,0x8) called from line 1139 of file fs/xfs/xfs_trans.c.  Return address = 0xf8cb7708
Filesystem "dm-0": Corruption of in-memory data detected.  Shutting down filesystem: dm-0
Please umount the filesystem, and rectify the problem(s)
Ending XFS recovery on filesystem: dm-0 (logdev: internal)
xfs_force_shutdown(dm-0,0x1) called from line 424 of file fs/xfs/xfs_rw.c.  Return address = 0xf8cb7708
xfs_force_shutdown(dm-0,0x1) called from line 424 of file fs/xfs/xfs_rw.c.  Return address = 0xf8cb7708


Can anyone please help me get my data off this thing?

With the partition being unmounted at the moment, can you a fsck on it to repairs the errors ?
Perhaps it's just a corrupt filesystem that can be fixed.

GoBieN,
Thanks for your reply, but AFAIK you cant run fsck on xfs filesystems or gpt partitions.
 
I ended up running xfs_repair -L md-0.
md-0 was the name of the LVM device.
I lost about 10% of my data due to corruption, but at least I got 90% back.  >:P
