[Lustre-discuss] OST redundancy between nodes?

[Gary Gogick]

Heya all,

I'm investigating potential solutions for a storage deployment.  Lustre
piqued my interest due to ease of scalability and awesome aggregate
throughput potential.

Wondering if there's any provision in Lustre for handling catastrophic loss
of a node containing an OST; eg. replication/mirroring of OSTs to other
nodes?

I'm gathering from the 1.8.0 documentation that there's no protection of
this sort for data other than underlying RAID configs on any individual
node, at least not without attempting to do some interesting stuff with
DRDB.  Just started looking at Lustre over the past day though, so I'd
totally appreciate an authoritative answer in case I'm misinterpreting the
documentation. :)

Thanks,
