Dear Joe, Dante,
Apologies in advance about not replying inline to your comments.
I am getting the impression here that DRBD is being considered as a
"remote" mirroring solution which makes it seems like the secondary
oss housing the backup OST is sitting far far away making it

Not quite. If an OST fails, only the objects on that OST become failed.
The filesystem will continue to run and service reques
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
