There is no in-built redundancy yet. Unless you setup something like drbd. Hope you find this information useful. Do keep us posted.
Hmmm... Having a failover to shared storage would be OK but would involve procuring 80TB of shared storage... Of course I could use node1-100 for filesystem1 and node101-200 for filesystem2 (some kind of drbd implementation). Weighing this against IBM's gpfs, which ain't free but they have a bit better redundancy I think... Any notes on performance? Has anyone tested write speed of say, 3TB or something?
