Hi there,

I am seeking some assistance with an XFS filesystem that will not mount. I have a Lacie NAS 5 Big Network 2 that has failed on me and basically I ended up losing access to my Shares and files.

While I have backed up what I could using Ufsexplorer, I can see that many folders are incomplete.

I have then set about removing the drives and connecting them to a Linux setup. $ of the drives are connected to Sata ports and the 5th is connected via a sata to usb adaptor.

Have reassembled the raid array, but when I try to mount the raid I get an error back stating that the 'structure needs cleaning.'

I performed xfs_repair -n /dev/md4 which fed back a huge amount of issues - namely the mismatch of UUID between the superblock and log files.

I am trying to save the report of this and sendf to you put having issues at the moment getting it to save the report correctly.

I am a complete Linux novice but would be interested to know if there is anyway to resolve this problem?

Regards,
Rob
