Hey all,
I’m 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:
[Wed Jul 1 07:14:30 2015] XFS (md1p3): Access to block zero in inode 70952984 start_block: 0 start_off: 0 blkcnt: 5 extent-state: 0 lastx: 8

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
