February 1, 20251 yr Looking for recommendations for my path forward. Followed the below as I was going to replace 2 4TB drives with 12TB. https://docs.unraid.net/legacy/FAQ/replacing-multiple-data-drives/ For reference I'll explain what I've done so far and how I ended up in this state using the /mnt/dsk locations. 4TB drive - disk 7 Stopped array, powered down and replaced disk7 with a 12 TB. No errors on SMART and latest preclear scripts used (as recommended). Array started and rebuild commences. Rebuild finishes successfully. Executed the following rsync command: rsync -avX /mnt/disk10/ /mnt/disk7 This completes successfully. Stopped and powered down the raid, pulled the 4TB that was disk 10 and replaced it with another 12 TB. Upon array coming back online, the original 12TB (disk7) is in an "unmountable: wrong or no file system" state. The 12TB (disk10) mounted successfully. I ran xfs_repair on disk7 via the GUI with the array in maintenance mode. No luck (no superblocks found). So I have an unmounted 12TB (which has the contents of 2 of my 4TB drives), a 12TB drive that is online (with nothing on it), and the two original 4TB that have been pulled but still have the data on them (drives have not been plugged in anywhere else). What is my best path forward?

February 2, 20251 yr Community Expert Still not entirely clear. Do you mean you had 2 parity + 11 data disks in the array before? And now 2 parity + 10 data disks after New Config?
February 2, 20251 yr Author Original array was 2 parity + 10 data Disk7 and 10 were 4TB drives replaced w/ 12TB drives. First drive was replaced using the 'safe method' from the link above (which is the drive that is now unmountable).
February 2, 20251 yr Community Expert Syslog is full of spam, in part because there appears to be a container constantly restarting, check their uptimes, then reboot and post new diags after array start.
