After replacing some drives (in order to add more capacity to the server) I found that when I clicked on the server share in the Unraid GUI, I saw the error: No listing: Too many files.

 

Looking at the log, I found: "Nov 19 08:44:29 Goliath2 kernel: XFS (md18): Unmount and run xfs_repair"

 

But there may be still other issues contributing to the problem I am having!

 

Is there a way to fix this without losing data? Although frustrating, on the upside, this is a backup server.

First thing is to run xfs_repair.

Done! Here are the result of the scan with repair and then again after the repair.

Looked kinda messy. Have you checked your lost+found share?

Should be fixed.

I still see this in the share:

 

"No listing: Too many files"

 

Here is the new log.

 

There are a bunch of files in the 'lost&found' folder now.

There's also fs corruption on disk21.

Fixed that drive and everything loads! I guess I have to figure out what files went into the 'Lost & Found' now.

Oh, THANK YOU for your help!

I am not understanding something. Does having a parity drive help recover data in this situation or does the data get corrupted on the parity drives as well?

Parity will usually be in sync with the corrupt data.

Parity has not knowledge of files, file systems, good or bad data.

If a bit changes on a data drive, the parity drive(s) is updated.

If a bit change causes the file system or a file to be corrupted, the parity system has no way to know that.
