Here it is attached.
I also see the following 2 errors in the node 2 logs which I assume mean the
problem is really that node1 is not getting demoted and I'm not sure why:
Error 1:
Sep 28 19:53:20 staging2 drbd[8587]: ERROR: mysqld: Called drbdadm -c
/etc/drbd.conf primary mysqld
Sep 28 19:53:20 staging2 drbd[8587]: ERROR: mysqld: Exit code 11
Sep 28 19:53:20 staging2 drbd[8587]: ERROR: mysqld: Command output:
Sep 28 19:53:20 staging2 lrmd: [1442]: info: RA output:

Sep 28 19:53:22 staging2 lrmd: [1442]: info: RA output:
(drbd_mysql:1:promote:stderr) 0: State change failed: (-1) Multiple
primaries not allowed by config
Error 2:
Sep 28 19:53:27 staging2 kernel: d-con mysqld: Requested state change failed
by peer: Refusing to be Primary while peer is not outdated (-7)
Sep 28 19:53:27 staging2 kernel: d-con mysqld: peer( Primary -> Unknown )
conn( Connected -> Disconnecting ) disk( UpToDate -> Outdated ) pdsk(
UpToDate -> DUnknown )
Sep 28 19:53:27 staging2 kernel: d-con mysqld: meta connection shut down by
peer.
Also, failover works fine if i reboot either machine. The outdated machines
comes back up as secondary. The scenario where i get the errors above is
when i pull the network cable from the primary. Is that a stonith device
that should be protecting from this scenario and potentially rebooting the
primary?
Feels like I'm getting so close to getting this working!
Thanks!
