Jul 7 11:47:58 qad01 pengine: [4359]: ERROR: unpack_rsc_op: Hard error
- mysql-server_start_0 failed with rc=3D6: 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=3D1000000)
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).=20
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.

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...

I think so. Regardless, to test a resource agent manually requires that=20
you define some variables and then call the script by hand. Also, check=20
all the actions (start,stop,restart,promote,etc) and their exit codes,=20
to see if they match the OCF RA specification. Most of the problems that
=20
you will have with a resource agent and it's resource can be found if=20
you're manually testing the RA script.
=20
Go to /usr/lib/ocf/resource.d/heartbeat/
Open the mysql RA script. Go to line 63 and starting from that line=20
update the values in the script to match the contents of /etc/my.cnf.=20
Then update the crm configure for the primitive mysql-server to match as
=20
well.
From what I remember, the values in=20
OCF_RESKEY_{binary_default,pid_default,socket_default} are wrong in the=20
RA script vs what's actually installed.
=20
Then "export OCF_ROOT=3D/usr/lib/ocf/" and all OCF_RESKEY_* with their=20
defined values, then call the script with no parameters. It should=20
provide the usage of the script. Then take step by step each action and=20
check it's exit code, see if it matches the OCF RA specification, and=20
also check to see if it actually starts the resource or not. The thing=20
is, once the script works as it should, all the issues have been=20
resolved, the cluster will work with the mysql-server resource.

Dan

<b>To:</b> The Pacemaker cluster resource manager<br>
<b>Subject:</b> Re: [Pacemaker] Upgraded mysql from 5.0 to 5.1 - And =
changed to
OCF RA<o:p></o:p></span></p>
</div>
</div>
<p class=3DMsoNormal><o:p> </o:p></p>
<p class=3DMsoNormal>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.<br>
<br>
When Pacemaker calls the mysql script, it goes through this code:<br>
<br>
<o:p></o:p></p>
<pre>####################################################################=
###<o:p></o:p></pre><pre># =
Initialization:<o:p></o:p></pre><pre><o:p> </o:p></pre><pre>: =
${OCF_FUNCTIONS_DIR=3D${OCF_ROOT}/resource.d/heartbeat}<o:p></o:p></pre><=
pre>. =
${OCF_FUNCTIONS_DIR}/.ocf-shellfuncs<o:p></o:p></pre><pre><o:p> </o:=
p></pre><pre>############################################################=
###########<o:p></o:p></pre>
<p class=3DMsoNormal>Which (as it says) initializes some environment =
variables,
then it can work with the mysql RA (Resource Agent). <br>
<br>
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.<br>
<br>
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".<br>
<br>
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 <a
href=3D"http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent=
-api.txt?rev=3DHEAD">http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/r=
esource-agent-api.txt?rev=3DHEAD</a><br>
<br>
How to test them is simple, follow the <a
href=3D"http://www.linux-ha.org/LSBResourceAgent">http://www.linux-ha.org=
/LSBResourceAgent</a>
guideline, just reference the exit codes from the first link. <br>
