[Lustre-discuss] Any production DRBD/Lustre deployments?

[Timh Bergström]

Hi Jordan,

No we do not stripe or drbd/raid our OSTs but our MDT/MGS data is
drbd:ed, backing storage is raid10 over 6 disks and then
primary/master over two mdt/mgs machines with drbd and heartbeat. And
we use it in production, if that is any help to you.
