April 14Apr 14 Community Expert Was hoping the array wouldn't be too out-of-sync with physical disk1, and you could New Config it back into the array, disable disk5 and try to rebuild it instead.But doesn't seem likely that would work now.Do you have a disk you can use to clone disk5? Even better, do you also have a disk you can use to rebuild disk1 to, and so keep existing physical disk1 as it is until we can see the results of rebuilding disk1?Or maybe just clone disk5, New Config physical disk1 back into the array, possibly check filesystem on either disk to repair if necessary, hope for the best, and accept whatever data loss results.

Sadly bad thing about not having access to the physical server is having to wait for my friend to do all this

Might be better if you could take care of this in person.

Or would his lack of experience with Unraid itself make it too complicated for him?I’m definitely willing to make the drive if I have to. But it would be easier (and cheaper lol) if I can give him the instructions and have him do it, of course while I’m confirming everything he’s doing.
April 16Apr 16 Community Expert First step is cloning disk5. Maybe even ddrescue since it seems to be failing.
