I have documented the first part of how to use DRBD with OpenVZ


Woohoo! I've had to pause my work, so I'm glad you've got something up there.

The info on (...) how to do updates (especially how to do OpenVZ kernel updates that contain a new version of DRBD, which is a little tricky) will follow soon.


Wonderful! That info, plus knowing which OpenVZ files to copy to the DRBD partition were my unknowns.


Question: Why not two DRBD partitions, one on each node, and run a handful of VPSes on the first node and a handful on the second, so that the second node's CPU cycles and RAM are not sitting idle? Or were you just trying to keep things simple?

If you do such a setup, DRBD's Group parameter is very helpful when you have two DRBD devices on one hard drive. The first group synchronizes, then the second, but not in parallel (as would be the case if you had two drives). Set one DRBD device in one group and the other in a new group.
