lvm doesn't support write barriers, but plain old ext3 on a device
mounted with -o barrier=1 does.

In the drbd8.pdf documentation it seems that drbd does indeed support
write barriers, but in a message at  Sep 12, 2008, 10:15 AM  on this
mailing list, it seems drbd does not.

Does drbd support write barriers?
If not (because it cannot guarantee the other side supports write
barriers), why is it that we know the local side supports write

Thanks a lot.
