one folder within a share is showing empty. ls show "structure needs cleaning"

Featured Replies

Woke up this morning to this alarming situation. One folder a few levels deep in one particular share appears empty. From the console, 'ls' displays the error: "/bin/ls: reading directory '.': Structure needs cleaning".

 

I'm panicking.

 

I have rebooted my unraid server. Still have the same problem.

 

All drives appear to be added to the array just fine. They are all xfs filesystem. The now-empty folder spans all the drives in the array, so I don't think it is a particular drive that is giving me problems.

Here you go. I have started to run checkfilesystem while in maintenance mode. Should I continue? I have done 6 of 10 of my drives. No errors so far.

Looks like disk8 is the problem, do that one

  • Author

OK. In the process. BTW, disk 9 also found problems. How did you determine disk 8 was an issue? What would have caused these errors? What can I do to prevent this in the future?

 

It looks like there might be some particular files affected and possibly being moved to lost+found. To fix this, is there a way other than examining each file and trying to figure out where it came from?

After finished checking, start in normal mode and post diagnostics

Probably not. We can see how bad it is after normal start
