yes, and we are using glusterfs 2.0.1

we have no problem on using the volume for reading data and if the
server is not under heavy load it works well for writing too, only
hangs when server is using 100% cpu for math intensise calculations
and we try to write a lot of data to glusterfs volume (it usually
takes some hours for it to hang)

It will be very difficult for us to migrate everything to xfs
now, but i will like to see someone having problems without xfs
not having that problems with xfs rather than people not having
problems saying that xfs is stable to start such large migration
process
