[Pacemaker] pacemaker + drbd + mysql = confusion

Hi all!


I had a working two-node-drbd-cluster with the following config. (Ubuntu
10.04 Server amd64, upgraded today)

node $id="05570095-f264-41ae-a609-768fd4a3b7e8" store2
node $id="e790fa15-1f91-4442-94e9-bf411519c4f8" store1
primitive drbd0 ocf:linbit:drbd \
	params drbd_resource="raid" \
	op monitor interval="15s" \
	op start interval="0" timeout="240s" \
	op stop interval="0" timeout="100s"
primitive fs_raid ocf:heartbeat:Filesystem \
	params device="/dev/drbd0" directory="/mnt/raid" fstype="ext4" \
	op start interval="0" timeout="60s" \
	op stop interval="0" timeout="60s"
ms ms_drbd0 drbd0 \
	meta master-max="1" master-node-max="1" clone-max="2"
clone-node-max="1" notify="true" target-role="Started" 
location ms_drbd0-master-on-store1 ms_drbd0 \ 
rule $id="ms_drbd0-master-on-store1-rule" $role="master" 100:
colocation fs_raid-on-ms-drbd0 inf: fs_raid ms_drbd0:Master
order ms_drbd0-before-fs_raid inf: ms_drbd0:promote fs_raid:start
property $id="cib-bootstrap-options" \
	dc-version="1.0.8-042548a451fce8400660f6031f4da6f0223dd5dd" \
	cluster-infrastructure="Heartbeat" \ no-quorum-policy="ignore"
	\ stonith-enabled="false"

Then I wanted to add mysql and later postgresql. I found several sample
configs but the problem is that the drbd resource is always named
"mysql" which is very confusing.

Basicly I would add something like that:

primitive mysql ocf:heartbeat:mysql
order mysql_after_drbd inf: fs_raid:promote mysql:start

right?

After playing around a while I messed up the whole thing. When I
paste my old config without any mysql settings I get:

WARNING: resource drbd_mysql is running, can't delete it
WARNING: resource mysqld is running, can't delete it
WARNING: resource ms_drbd_mysql is running, can't delete it

How can I start over again?

I had no success with postgresql either. The configuration went ok but
then I got:

pgsql_start_0 (node=store1, call=6, rc=5, status=complete): not
installed

What is missing?

Thank you for hints and your patience!

Regards,

Oliver
