Hello! I have several questions about Lustre.
First of all, ClusterFS has commercial support and on the page http://www.lustre.org/architecture.html I see following: "On the download pages you can find a ***sample experimental implementation*** of some the components above. We hope to enhance many of these and many other components as time goes along. Much documentation can be found on this site." Does it mean that there are two separate versions of Lustre file system: one commercially supported and another one commercially supported? Second, I want to build system consisting of several frontend-nodes and two-four backend (storage) nodes. I don't want to use hardware shared storage for some reasons. So, I can use some networking block device to connect two nodes (e.g. DRBD v0.8 in primary/primary mode) if needed. The question, is it possible to setup Lustre in such configuration: 1) over DRBD or local hard drives if possible on two or four storage nodes; 2) to be able mount Lustre file system at frontend nodes which have no direct access to shared storage device, i.g. is it possible to mount Lustre over network?; 3) to have failover and load-balancing storage nodes, so each node will hold entire copy of stored data, so storage nodes can be accessed in parallel and if one node goes down, system will function correctly. Is Lustre file system suitable for this? Thank you. _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
