Problem with file system on iSCSI FileIO

[Slawomir Nowakowski]

Dear Sir,

We are using iSCSI FileIO on the LVM. The file (called lun) has been 
initialized with:
dd if=/dev/zero of=/dev/vg+vg00/lv+i+lv0000 bs=1M conv=notrunc

on the XFS formatted logical volume.

Additionally, we use 2.6.27-39 kernel  and xfs-tools 2.10.1

After some time, without any additional errors, we are not able mount 
the volume. After mount command we get:


"mount: Structure needs cleaning"

in dmesg we can see:

"XFS: failed to read root inode"

If we run the xfs_repair, the lun file will be removed and all data on 
the iSCSI FileIO volume is lost.

I have found in the FAQ that this can be everything:

http://xfs.org/index.php/XFS_FAQ#Q:_I_see_applications_returning_error_990_or_.22Structure_needs_cleaning.22.2C_what_is_wrong.3F

But do you know if it is possible to recover the data somehow?

Thanks in advance for response
