I, too, have been on a long quest for the holy grail of 100% uptime.
Yes, Lustre is suited for this better than most. Lustre itself won't do the replication, though, although they are planning just such a feature in the future. You can use Lustre combined with drbd (for network mirroring) or a SAN and some heartbeating software (such as Heartbeat) for failover of the services.
However, you would have at least some sort of delay during the failover; it would not be instantaneous. I don't know how quick you can make it.

Hello! I'm looking good cluster fs for a while and I'm very sad that I didn't found any solution with 100% failproof. Only one I know now its googleFS, but its closed project, used by google, not open source. I'm ,ooking for a cluster file system with replicating - in simple example: 10 nodes, each with hard disk. Each stripe is residing always on 2 or more node. So I can power off any 1 node on any time, and clients have 100% stability - there is no error/outage, 100% SPOF free. Can it be done with Lustre? -- Best regards, Darek All your base belong to Me. _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
