[Lustre-discuss] DRBD + active/active OST, again

[Andrew Godziuk]

Johann,

Thank you for your detailed answer, this made the picture much more clear.

Then I guess this part of manual should be changed:

"The active/passive configuration is seldom used for OST servers as it
doubles hardware costs without improving performance. On the other
hand, an active/active cluster configuration can improve performance
by serving and providing arbitrary failover protection to a number of
OSTs."

to state explicitly that active/active scenario is only possible when
OSS is active for some OSTs and passive for some others.
