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. -- Andrzej Godziuk http://CloudAccess.net/ _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
