[Lustre-discuss] lustre and multi path

[Klaus Steden]

Hi Brock,

I've got a Sun StorageTek array hooked up to one of our clusters, and I'm
using labels instead of multi-pathing. We've got it hooked up in a similar
fashion as Stuart; it's a bit "slow and sloppy" when initializing, but it
works well enough and there are no problems once OSTs are online.
