I have I really bad situation. A broken enclosure with 2 drives (RAID 1) using XFS file system. 1 drive didn't start up cause of powerfailure from the enclosure but span up with a different.
Here's the problem, the working drive only contains system folders from the NAS-system, but the 'user'-area is blank.
Viewing in HEX only 0000000, the same with the broken one. It's journal-based so if I'm not misstaken it is using 256mb in a special partition and this partition belonged to the 'broken' area of 1 drive.
Even if it was created in a non x86-arch it should be visible in HEX?
Best regards

Sure it was Raid1 ?
Find XFS boot , and mount it with Linux or with UFS explorer to check .
ABout 00000 in user area , sure you have checked all space?
For XFS it is normal, some valuable data could be stored even near at the end of the storage .

Yes, checked the logfile using the UFS explorer to see wich RAID. The zeros, seen more than just one drive with this. This is the second NAS-system with the same problem. The last one using SPARC zfs. The UFS explorer together with HEX, I'm able to see the partition with root folders for the linux-system itself but no user data. All space checked, still 0000, only very small pieces of information.

Doesn't matter, cause the encrypted data should still be visible in HEX. Cannot remember if the encrypt the data, only software then I think.
Best regards

The encryption on WD works through USB Bridge, the NAS units do not use USB so I assume is not with encryption.
