January 18, 20242 yr Hello all, I've got two 10TB drives that have failed, the first is Parity 1, and the other is drive 11. I couldn't find any 10TB locally, but ended up with two 12TB drives. Is there a way for me to replace the parity drives with the new 12TB and then use the existing remaining good parity drive for the drive 11 replacement? Does the Parity swap procedure work with multiple failed drives? Screenshot and diags attached. raptor-unraid-diagnostics-20240118-1631.zip
January 19, 20242 yr Solution I would add new parity1 first, then do a parity swap for the other disk.

January 30, 20242 yr Author Sorry it's been a bit since I replied, but I ended up having issues with my server I've been trying to sort out. I managed to get one of the 12TB drives added as parity, and that was good and the process completed without issues. I then attempted the parity swap procedure for the remaining 12TB / bad drive following the process linked. This got to about 80% and the server rebooted. I had several other issues with reboots attempting the process again so I finally just removed the second parity drive from the config, and physically removed the failed 10TB data drive & assigned the old 10TB parity to the failed data drive and let the data-rebuild process take over. This completed without issues. All drives have a green dot, but the rebuilt drive shows "Unmountable: Wrong or no file system" Do I need another reboot, or do I need to format the unmountable disk? raptor-unraid-diagnostics-20240130-0937.zip
January 30, 20242 yr Check filesystem on disk11, run it without -n. P.S. several disk related issues logged, look like a power/connection issue, PSU could be on the way out.
January 30, 20242 yr Author Thanks for the guidance. Looks like it made some changes. Attached is the results. diskcheck_output.txt
January 30, 20242 yr Author It is mounted, and there is a lost and found folder with tons of files and folders. Guessing there's not an automated way to get those back where they were? Can I use something like krusader to move them without too much issue?

The whole point of the lost+found folder is that the files in there are ones for which Unraid could not locate the directory entries required to give them their correct path or filename. You may find therefore find files or folder with cryptic numeric names and in such cases it takes a manual operation to work out what their names should be. The Linxux 'file' command can help with that by at least telling you the type of the any files that are there.
