You can't do a drbd0.8-style active/active, i.e. you can't have a single storage partition be served by multiple servers simultaneously.
Actually, drbd 0.8 allows for both nodes to be masters now -- I was wondering if this what you meant by active/active on nodes.
However, you can serve different partitions/disks/logical volumes/whatever from different servers and be active/active that way (Lustre will merge all these different partitions into one filesystem, or for however many you have it configured). If one node fails, you just failover its partitions to the drbd "sister" server.
That is indeed our current setup -- however, that makes an active/passive setup where the replicated drbd partitions are passively standing by till heartbeat fails them over (and makes them primary).
We're not in production, yet, (we still have to figure out the stale nfs file handle issue when exporting via NFS that was mentioned a few messages ago), but it seems to work fine. Failover can be slow due to the client reconnect timer, but that is tweakable.
Appreciate your quick response, thank you and good luck! Regards, -- Mustafa A. Hashmi [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
