So I took Dan's advice this time and cleaned up my resource
configuration, updated the script, and verified...however I'm still not
getting the resource online...
[root at qad01 heartbeat]# crm resource start mysql-server

Subject: Re: [Pacemaker] Upgraded mysql from 5.0 to 5.1

Have you copied twice this line?
socket="/var/lib/mysql/mysql.sock" binary="/usr/sbin/mysqld"
socket="/var/lib/mysql/mysql.sock" binary="/usr/sbin/mysqld"
I think so. Regardless, to test a resource agent manually requires that
you define some variables and then call the script by hand. Also, check
all the actions (start,stop,restart,promote,etc) and their exit codes,
to see if they match the OCF RA specification. Most of the problems that
you will have with a resource agent and it's resource can be found if
you're manually testing the RA script.
Go to /usr/lib/ocf/resource.d/heartbeat/
Open the mysql RA script. Go to line 63 and starting from that line
update the values in the script to match the contents of /etc/my.cnf.
Then update the crm configure for the primitive mysql-server to match as
well.
From what I remember, the values in
OCF_RESKEY_{binary_default,pid_default,socket_default} are wrong in the
RA script vs what's actually installed.
Then "export OCF_ROOT=/usr/lib/ocf/" and all OCF_RESKEY_* with their
defined values, then call the script with no parameters. It should
provide the usage of the script. 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 thing
is, once the script works as it should, all the issues have been
resolved, the cluster will work with the mysql-server resource.

Dan
