Hi!
Using lessfs on top of an XFS on top on a software RAID-5 and see this
freeze happening about once a week. Usually during heavy load.
No comments on the stuff below? Nobody else?
I also have frequent freezes on two raid5 arrays on different systems.
kernels tested are 3.1 and 3.2.
system1: raid5-xfs-btrfs loop
system2: raid5-btrfs
when the freezes happen, iostat -xk 1 gives 100% usage on one random
disk.
Here are some kernel messages from the raid5-xfs-loop btrfs system.

Any hints? Or any debugging I can do to help? I did find a similar cas from
2008, but that is supposed to be fixed now.
This also started after updating the kernel to the 3.x series. At the moment
using 3.2.2 and still seeing it.
