Kernel oops when using XFS

[Tal Maoz <magogo200@xxxxxxxxx>]

Hey all,

Â

Iâm using XFS on a Ubuntu 14.04.1 x84_64 machine and getting kernel oops messages from the XFS module almost daily.

My machine is a 6-core Core-i7 with 24GB RAM, an mdadm software raid5 over 4 disks with an XFS fs on it.

Here is a typical error message:

I have gathered some information that I hope can help figure out what the problem is. FYI, this sort of problem also happened when I had an Ubuntu 12.04 installed with the same raid configuration:

What could be the problem?

I have another mdadm raid5 array that used to have XFS and gave the same errors. I use it for backup and noticed that each backup from the main array to the second one used to take a long time and gave these errors. I switched from XFS to ext4 and not only did the errors go away (obvisouly...) but the backup time went down from almost 23 hours to 1 hour!

Thanks,

Tal
