Common case is use of Linux-HA to manage primary/backup for each OST/MDT.

There is likely even something in the Lustre manual. > On Thu, Aug 14, 2008 at 3:05 AM, Andrea Frittoli > <[EMAIL PROTECTED]> wrote: > > I'm trying a Lustre + DRBD set-up, I would like to use DRBD with the > > following setup: > > > > on MDS: DRBD emulates an MDT on shared storage.
