[Aoetools-discuss] drbd + aoe

[Justin A. <ju...@vl...>]

I'm setting up a redundant aoe target with drbd.
These two aoe target servers export both the same drbd device through
aoe  at the same time using a drbd primary/primary setup.

Initially I assumed I had to run the aoe (qoaed/vblade) in o_direct mode
to be sure all writes would be replicated realtime.
But is this really necessary?   Is vblade or qaoed buffering writes?
Initial test show a  big decrease in  performance when using o_direct on
a drbd device...
I'm assuming the drbd buffers are also replicated...
