[DRBD-user] drbd with heartbeat won't fail over

[Dan Gahlinger]

I posted this in linux-ha but got no response, and didn't even see my post
get to the list.
so here it is here. seems more like a drbd issue anyhow.

I have two systems, with heartbeat and DRBD installed.
Initially I tested with just DRBD, and was able to fail back and forth very
well and easily.

However, when using heartbeat, it won't fail over, no matter what I do.
status doesn't change.

I have it setup so that DRBD goes over a cross-over cable between the two
systems on a private IP.
and heartbeat is run over the public (internet facing) interfaces.

My heartbeat config looks like this:

vi /etc/ha.d/ha.cf -
logfacility local0

logfile /var/log/ha-log

debugfile /var/log/ha-debug

udpport 694

keepalive 1

deadtime 60

bcast eth0

node LAB-TEST-01

node LAB-TEST-02

auto_failback on

and /etc/ha.d/haresources (note IP address is the virtual public IP):

lab-test-01 192.168.10.218 drbddisk Filesystem::/dev/drbd0::/mysql::ext3
Filesystem::/dev/drbd1::/data::ext3
configs on both systems are the same, hosts files identical with all the
entries.
I've tried with auto_failback on and off seems to make no difference.

I test by pulling the public cable on lab-test-01, or using ifconfig eth0
down

Also, when I bring the server back up drbd can't see the other system
(either one), it becomes
secondary/unknown and primary/unknown.

It seems for some cases I need to use the drbdadm primary all on the primary
at boot up to fix that.
One other note about the heartbeat issue above. I found if I enter the
commands manually it seems to work.
which makes it really weird.

Can anyone tell me what's going wrong?

Dan.
