Florian,
I'm sure I'm just missing something. Probably a timing thing. I added
the lines to drbd.conf and ha.cf per the instructions on your
blog (see below for for full file.) Brought up the system and made sure
it was correctly primary on node1 and secondary on node2. On node1, if
I do a "halt" on the machine or restart heartbeat it correctly brings up
node2 as primary. If I pull the plug on node1, then node2 is being set
to outdated so heartbeat can't bring it up. Can you tell me what I'm
missing? Just FYI (in case it makes a difference) I'm running this in 2
VMServer's as a test bed.
The sample drbd.conf shows:
# "resource-only" -> Call the outdate-peer handler if we primary and
# loose the connection to the secondary. As well
# whenn a unconnected secondary wants to become
# primary.
If I power off node1, how is node2 getting the command to outdate drbd?
Thoughts?
