Hi Shambhu- I believe neither the ldiskfs nor ZFS OSDs support an active-active configuration (except in the sense that one can have multiple targets, some of which are active on one host and others on another). It seems reasonable to me, only having used DRBD and Lustre independently of each other, that it would be possible to use DRBD in active-passive mode in place of shared storage for fail-over, but with inferior performance. Clients would connect to whichever server is currently active for a particular target.
If instead what you're talking about is mounting a filesystem for simultaneous use on the DRBD hosts themselves, you're looking for a "shared-disk" clustered filesystem, not Lustre, which is a "distributed" clustered filesystem. -Laura _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
