Hi there,

two days ago my server crashed for unknown reasons. Restartet, parity check went through (5 errors, seems reasonable for a crash). In the "fix common problems" plugin I got the error "Unable to write to disk7 - Drive mounted read-only or completely full.", with a link to more information. That info seems to be mainly about caches; it's an array disk tho. If I google the error, I didn't found much info, but restarting seemingly fixed it.

So I did a clean restart yesterday, the message was gone - and now, it re-appeared. As you can see in the screenshot, the disk is not full, and had reads+writes since the restart yesterday, and not considerably less than some other disks. The Main Page also shows 0 errors.

What to do now? Should I probably throw it out and rebuild? I added diagnostics in case they are useful

Best Regards

Oct 16 16:06:39 LuNAS kernel: XFS (md7p1): Corruption detected. Unmount and run xfs_repair

Check filesystem on that disk.

Hi there Jorge,

I did as mentioned in the link. It indeed found a corruption, I hit "fix" afterwards, and it fixed it. Checked again, all good
Now the burning question is if this happened because of the crash, or if the crash happened because of the corruption. Will definitely keep an eye on disk7.

Thank you so much!
