June 30, 20233 yr Issue: Drive 6 is showing Unmountable disk present: Unsupported or no file system. Background: Moved my UNRAID server built on a 45 drives Storinator from Japan to the US. Plugged all the drives back in and booted it up, Drive 6 showed failed. Shut the system down, pulled the old drive, and put in a new Western Digital 14TB. Added it to the array as Drive 6 and UNRAID did the rebuild on it as expected. Took just about a day. Came back after work last night and now it shows the error stated above. Did a SMART check on drive 6 and it passed with no issues. Unsure what to do next. Disk 12 is an expansion drive that's in the process of being cleared and added to the array. I didn't realize Drive 6 had the error when I started the expansion! Diags: hades-diagnostics-20230630-1300.zip Any thoughts would be appreciated!

July 1, 20233 yr Author Interesting, when the new addition finished it also gave the same issue. Running the command above gave: Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... Then the scondary superblock just ran with ..... afterwards.
July 2, 20233 yr Community Expert That confirms there's no valid XFS filesystem on that disk, I assume the original disk was formatted XFS like the other ones? If you still have the old disk and an extra SATA port connect it to the server and see if it mounts with UD.
July 2, 20233 yr Author When you say "Mounts with UD" what do you mean? The old drive was XFS - but iirc when I created the array it just did all of that automatically. When I put the new drive in, I added it in slot 6 in the array, and started it up. Did I do this wrong? Should I have formatted it as XFS first and then added it to the array?

I'm not sure since the diags don't show the initial replacement, but the replacement disk had the filesystem set to auto, and that is not normal, so something out of the ordinary happened. 17 hours ago, JasenHicks said: When you say "Mounts with UD" what do you mean? Install the Unassigned Devices plugin and see if old disk6 can be mounted and its data accessed.
