Thanks for the fast reply! I ran XFS repair from the GUI. So would you suggest removing the drive and trying the Windows tool then as the best option? Just to confirm then, the Parity backup is bad then, so I need to completely start from scratch with the whole array?

Hi all, I found a few threads on similar problems, but none exactly matching my case. I think I had a power cut which resulted in my server being shut down. I can't be sure, I've had some electrical work done and it might be the electrician cut the power to do some work without me realising while I was at work. Anyway, I don't know when it happened, but then I noticed one of the 8TB disks in the array gave the "Unmountable: Wrong or no file system" error. I used Check Filesystem Status to run xfs_repair and it gave: Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... followed by an unlimited number of periods. After running for half a day or so, it finally gave: Sorry, could not find valid secondary superblock Exiting now. I ran an extended SMART test, and there didn't seem to be major errors, but likely I just don't understand what I'm looking at: === START OF INFORMATION SECTION === Model Family: Toshiba N300/MN NAS HDD Device Model: TOSHIBA HDWG480 Serial Number: LU WWN Device Id: 5 000039 b18c8a0ab Firmware Version: 0601 User Capacity: 8,001,563,222,016 bytes [8.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 7200 rpm Form Factor: 3.5 inches Device is: In smartctl database 7.3/5417 ATA Version is: ACS-3 T13/2161-D revision 5 SATA Version is: SATA 3.3, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Sun Jun 18 19:33:38 2023 CEST SMART support is: Available - device has SMART capability.

I tried removing the drive from the array, unmounting it, reformatting it and then remounting it, hoping that the Data-Rebuild would fix it, but once it did, it was still showing as Unmountable: Wrong or no file system. So I'm guessing the parity drive backed it up in a corrupted state? My worry is, if that's the case, then even if I get a replacement drive, then Data-Rebuild will just fill it with corrupted data? Or am I completely wrong? Does it look like the drive is bad and I should get rid of it? Any help is much appreciated.
