Hello, I'm evaluating drbd and heartbeat, and have a very simple problem that I'm sure others have tackled. I have two machines, A and B, both running drbd. Let's consider A to be the primary, and B to be the secondary. I would like heartbeat to switch B to the primary drbd in the event of A crashing. I do not wish to share an IP between the two machines - I just want something like this executed on B: drbdadm primary all ; mount /dev/drbd0 /mnt/drbd0 I've been reading the heartbeat (1.2.x) docs and I'm sure this is possible, however while I have drbd doing precisely what I want it to do (I'm using gentoo - I emerged, quicky configured and it "just worked"), I can not get heartbeat working properly. So my question is: Is this possible and does anyone have it working? If so, do you fancy sharing some heartbeat configuration files (ha.cf and haresources). I also have another thought; if A crashes, and B takes over, I do not wish A become the primary as soon as it comes back online, or rather, what I'd like is a "flip flop" effect. When A crashes and comes back online, I wish it to become the secondary drbd instance, resync, and not become the primary until B goes offline. Thanks in advance, and Merry Christmas. John
