Something weird happen, I shutdown ( to take the failed 14TB drive that was unassign status) that looked to be a clean shutdown. But I got a message shutdown was not clean. I had to start the array manually. Then unraid started to do a parity check. I have the parity on pause right now. Just wondering what happen?

Should I let the parity check run or cancel? I know sometimes if the Unraid server has a power failure or some kind of crash parity will automatically start after reboot. But this did not happen.

You can check parity later.

you need to check filesystem on disk7

Also, you should clean up your plugins, you have several installed that are incompatible or have been replaced.

Oh I will follow these steps to check the xfs file system type. Thanks

It's XFS.

Start in Maintenance mode, click on the disk to get to its page, check filesystem

Output file.

Newer versions of Unraid make this simpler by giving you buttons to continue with the next steps.

You have to remove -n (nomodify) and do it again.

Oh wow. Thank you.

I removed the -n and click on check. I seem to flash and then added the -n back...

  • Community Expert

Start the array in normal (not maintenance) mode and post new diagnostics

  • Community Expert

Looks like disk7 was repaired, but some of it went to lost+found.

On the user shares page, click Compute... for the lost+found share, wait for the results, then post a screenshot

Compute All, right?

That will take a lot longer than just

Looking for the compute only option...

  • Community Expert

Each share has a Compute... on the same line where it is listed in your screenshot.

So you have 54.1G in lost+found.

You can examine the contents in the File Manager by clicking the "arrow box" icon at the left of that same line.

Sometimes repair won't know what folder a file belongs in, or what name a folder or file should have.

Linux 'file' command can help tell you what kind of data is in a file so you can try to open it in an appropriate application to try to identify it.

I click on some of the folders I see some TV programs I recorded in Plex. I by mistake click on one of the flies image.pngand now it is processing something. I have to figure how to stop the process.

  • Author

I exited out and went back in. Looks like the process stop.

Just observed my fans running fast and loud. Checked temperature and drives, all seem okay. Rebooted server and now the array did not start.
