I'm not sure if >4TB devices are supposed to work on x86_64 or not, but
they don't seem to.  I have not been able to produce a stable drbd
system with a 9TB block device.  I initially used the skip initial sync
method which probably masked the problem, however, I tried to doing the
full-sync and it fails (see below).  Can anyone clarify the status of
>4TB devices on x86_64 please?

Thanks.
