To report back, UFS explorer was able to recover all the data on the old disk 5. But nothing from disk 2 or disk 5. The server is back up and running but a couple of TB is missing. Im probably going to invest in a second server with somthing like 3x18TB and use that as the main server and this old one as backup, sometime in the future. Thank you again for all the replies and the help!

Okay, I'll give it a try and then report back. Thank you for all the help

Okay, its rebuilt now. Whats the next step? Remove the disk and try to retreive the data with UFX Explorer or some tool? Save that data some place safe outside unraid then format disk2 and disk5?

Okay Im rebuilding right now. It looks like its writing to disk5 but its still unmountable, think that will change once its done?

Okay so the repair on disk5 returned this: Phase 1 - find and verify superblock... couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!! attempting to find secondary superblock... .. ....found candidate secondary superblock... unable to verify superblock, continuing... .found candidate secondary superblock... unable to verify superblock, continuing... unable to verify superblock, continuing... unable to verify superblock, continuing... Exiting now. Is the brand new replacement disk for disk5 no good?

But will it find a superblock and that stuff if its a brand new drive that havnt been formated?

Should I rebuild disk5 before removing disk2? Is it possible to rebuild before formating? Right now it says unmountable on both disk2 and disk5, but I looks like I still can rebuild. But at the same time the option to format is available (checkbox with Format will create a file system in all Unmountable disks.) Or should I first set filesystem to xfs on disk5, and do the repair? Will that remove the unmountable flag on the disk? Sorry for the many questions, at this point Im afraid to do anything and lose even more..

Yeah I heard about UFS explorer so might give that a go. If I somehow recover the data from disk2 and copy it to unraid, will everything be back? Or will some things be forever lost since two drives failed at once? Is it safe to remove disk2 and rebuild the array with one disk missing?

Thanks alot for trying! No backup unfortunately.. Im thinking I should disconnect disk2 and see if I can recover the data some other way. Whats the best solution to limit the damage on unraid? Remove disk2 (and replace it when I get a new disk), format the new disk5 and rebuild?

Same thing again Im afraid.

This is what I got (but with thousands of periods) Phase 1 - find and verify superblock... couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!! attempting to find secondary superblock... ..........................................................................................................................................................................................................................................................................................................................................................................................................

Here it comes! And thanks again for helping out! file-server-diagnostics-20220929-2001.zip

Yeah Im using the GUI now file-server-diagnostics-20220929-1838.zip

Same thing again, "Sorry, could not find valid secondary superblock"

When I try to do it in the webUI I cant see "Check Filesystem Status" on drive2, its on the other drives though
