XFS internal error

[Max Waterman <davidmaxwaterman+kernel@fastmail.co.uk>]

Hi,

I have just had an XFS error occur while deleting some directory
hierarchy. I hope this is the correct place to report it.

It essentially shutdown the file system, and a reboot seemed to return
everything to normal.

This is in syslog :

I am fairly sure there is nothing I can do about this, but I thought it
prudent to mention it. Searching turned up some similar issues, but they
seem related to a previous kernel version and claimed to be fixed in
subsequent versions.

The array is a little 'unorthodox', if that matters.

It's using 4 on-board(nforce) sata drives and 4 PCI IDE drives :
