f an active/active setup is possible.
Better think about using your two-node DRBD as a iSCSI portal for the virtual
machines. Your can set this up with three nodes making the virtual machines
free moveable between all nodes in the cluster.

Hm,
somethings do not fit together. You configured a rate of 102M (Byte/s) and
when you ask the DRBD it tells you that your configured a rate of 11M (Byte/s)
Did your show us the /proc/drbd output of the above given config?

do with it. But from out measurments with bonnie we learned that the
performance of the drives if the bottleneck and not thethroughput of the

Hi,
I wanted to know if a dual primary DRBD setup, exporting the block devices as
