[Pacemaker] Upgraded mysql from 5.0 to 5.1 - And changed to OCF RA

I think I didn't explain enough of the config, therefore the confusion. 
There are 2 ways the script /usr/lib/ocf/resource.d/heartbeat/mysql is 
called. First is by the cluster resource manager, Pacemaker, and second 
is manually by you.

When Pacemaker calls the mysql script, it goes through this code:

#######################################################################
# Initialization:

: ${OCF_FUNCTIONS_DIR=${OCF_ROOT}/resource.d/heartbeat}
. ${OCF_FUNCTIONS_DIR}/.ocf-shellfuncs

#######################################################################

Which (as it says) initializes some environment variables, then it can 
work with the mysql RA (Resource Agent).

When you run the script, manually, you don't have to add the export 
commands to the script, that _could_ mess it up when Pacemaker calls it, 
you run the export commands from the shell, creating (in the current 
shell) the environment that you need to test the mysql script. So, 
remove the export lines from the script, as I can see from your output, 
it seems that the script works OK with the mysql server.

But, when running a resource manually, either via mysql RA script or via 
LSB init script, it doesn't mean Pacemaker is aware of this, therefore 
when running "crm status", the resource doesn't show up. You check the 
script manually to see if there are any issues in running it, then you 
use the cluster resource manager to start the resource and check it from 
"crm status".

I've also previously said "Then take step by step each action and check 
it's exit code, see if it matches the OCF RA specification, and also 
check to see if it actually starts the resource or not". The 
specification draft for the RA exit codes can be found at 
http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?rev=HEAD

How to test them is simple, follow the 
http://www.linux-ha.org/LSBResourceAgent guideline, just reference the 
exit codes from the first link.

 From the logs, I see that the mysql-server primitive returned rc=6 
(exit 6), which means "program is not configured".

Jul  7 11:47:58 qad01 pengine: [4359]: ERROR: unpack_rsc_op: Hard error
- mysql-server_start_0 failed with rc=6: Preventing mysql-server from
re-starting anywhere in the cluster

Because the mysql-server primitive and/or the mysql RA were not properly 
configured at the time the error message was written, it led to:

Jul  7 11:47:58 qad01 pengine: [4359]: WARN: common_apply_stickiness:
Forcing mysql-server away from qad01 after 1000000 failures
(max=1000000)


Therefore, export the variables manually, check the exit codes on each 
operation of the script, they should match normal operation as described 
in the RA specification draft, if everything is OK, move on the the crm 
shell, cleanup the mysql-server resource, cleanup the max failures (the 
cluster resource manager keeps track of these, I've had to manually 
remove everything from /var/lib/heartbeat/crm/*, haven't found a way to 
clear this option, yet, and loaded the saved config with crm load 
config.crm to have the cluster functional again).

Also keep in mind that the mysql RA script needs to be the same (as well 
as /etc/my.cnf) on all cluster nodes, and even if Pacemaker propagates 
the changes to all nodes via multicast, /var/lib/heartbeat/crm/* files 
are placed on all cluster nodes as well. And the mysql RA script needs 
to work the same way on all nodes.

And I'll stop, I've said enough already.

Cheers.
