Dear Linbit staff,

first, thanks for DRBD!

Second, what is your personal recommendation for a rock-solid
2-node active/passive HA cluster setup?

If possible, please choose any combination from:

  - 0.7
  - 8.0

- Heartbeat
  - 1.x
    - drbddisk LSB RA
  - 2.x with 1.x features (without CRM)
    - drbddisk LSB RA
  - 2.x with 2.x features (with CRM)
    - drbddisk LSB RA
    - drbd OCF RA

Can you also explain in what case I should (not) be using:
- /usr/lib/heartbeat/dopd + /usr/lib/heartbeat/drbd-peer-outdater
- fencing "resource-only" vs. "resource-and-stonith" (when I have
  configured Heartbeat with STONITH)

It seems like Linbit has not yet fallen in love with the
features of Heartbeat 2.x and the drbd OCF RA :)
I was talking to lmb about this and he said it was primarily a
lack of time that there wasn't yet a 100% solid solution for
the combination of DRBD-8 and the drbd OCF RA.
Can we do something about that?
Could you guys have a look at the drbd OCF RA?
