October 24, 20232 yr Background in my previous post: I had a failed drive and purchased a new, bigger one and ran a parity swap and rebuild. Everything was going according to instructions until I open up to see how the Data-Rebuild went and see the message (screen shot attached): "Data-Rebuilding finished (21 errors) Canceled". The [previously parity] disk drive that was being rebuilt is still listed as "Unmountable: Unsupported or no file system" despite xfs being listed as the FS (after the rebuild). A couple questions: Did I lose the ability to rebuild that drive from the parity+other data drives (and lose a large portion of my data )? How do I get that drive working in my array? If I lost the data, is it just a matter of formatting (the option is below on Main)? Attached latest diagnostics and a couple screen shots. Edit: I did run a quick SMART check on that 0SW disk after the canceled rebuild, it passed, attached. untower-diagnostics-20231024-0619.zip untower-smart-20231024-0611.zip untower-smart-20231024-0611.zip Edited October 24, 20232 yr by mattz added SMART log and note

As for the unmountbale disk, check filesystem on disk3, run it without -n. P.S.: when the emulated disk is unmountable you should do this before rebuilding.

It's running with what looks like all my original data! This is a huge relief. I restarted the server in Safe Mode before I ran that check. The checkbox to "rebuild from parity" was available, but I ignored that and started the array in maintenance mode. I think at that point it was already OK since it wasn't asking me to format the drive. I ran the check, via the WebGUI and it didn't have any suggestions. Started the array in regular mode and it worked! Thank you.
