All, I'm hoping to set up a Lustre file system using 1 MGS and 3 OST on 4 separate pieces of hardware, but I'm doing this and hoping to gain some reliability at the same time. The problem that I see is that if any one piece of the 4-node system fails, the whole system will fail.
Is it possible to configure Lustre to write Objects to more than 1 node simultaneously such that I am guaranteed that if one node goes down that all files are still accessible? This would effectively mean that I would use 2 times the storage space for each object written and would require that every cluster have a minimum of 2 nodes. I understand the concepts of using DRBD and replicating block devices as well as creating a full separate cluster for fail-over, but I'm hoping to build redundancy into a single cluster without having to duplicate my network with a bunch of active/passive machine combinations. -- Dante _______________________________________________ Lustre-discuss mailing list Lustre-discuss@clusterfs.com https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
