/usr/sbin/crm is a python script. Inspecting the code, it appears to be hardcoded:
ocf_root = os.getenv("/usr/lib/ocf")
if not ocf_root:
ocf_root = "/usr/lib/ocf"
dir = ocf_root + "/resource.d"
Thus, you should make sure the directory is present, contains the appropriate
resources, and is readable and executable by root.

Hum.... I see.
Any ideia of how(where) to configure CRM to know where resource agents are?

Yes, I was showing you what should be there.
These items are stored in /usr/lib/ocf/resource.d/ for me on CentOS 5.2. It
means your CRM does not know where your resource agents are kept, which means
your configuration is probably screwed up (it’s pointed to the wrong directory)
or you are just missing the files.

I did that but no class is listed.

This is the problem.

Hi Eliot,
thanks for your quick answer.
I have already read all links you have mentioned. I am studying this a lot and
making some progress.
But the thing is: I think there is something strange because, as I mentioned,
crm ra classes shows nothing. Is this normal?
The only resource I got runnig was a failovre IP one. To get this I created a
primitive with
primitive failover-ip ocf:heartbeat:IPaddr \
params ip="172.27.17.210" \
op monitor interval="10s"
and it is working fine.
I would like to have a shell script monitored by Pacemaker. But I have not
found a way to do it yet.
thanks again,
Alan

First, read this (probably ten times or so, since it won’t make complete sense
and you will miss various details the first couple of times):
http://clusterlabs.org/mediawiki/images/f/fb/Configuration_Explained.pdf
Then, if you want to use the CLI, read this:
http://clusterlabs.org/mediawiki/images/8/8d/Crm_cli.pdf
Or check out any other links on that main documentation site.
I strongly recommend you start out learning with the XML CIB and then, if you
want, move to the CLI. Everything makes much more sense if you understand the
XML stuff. However, keep in mind that there is a steep learning curve to all of
this. I have been working with it 3-4 days a week for over a month now, and
there are still some things I don’t fully understand. By “working with it” I
mean I have written 3 resource agents, one of which is a 800+ line Master/Slave
RA, and a 600+ line XML CIB using every form of primitive, clones, master/slave
resources, groups, location constraints, co-location constraints, all forms of
rules, etc. So, when I say that I’ve done all that and I _still_ don’t fully
understand everything about this system, that should give you some idea just
how much there is to learn. Don’t expect to have it mastered in a couple of
days.

Subject: [Pacemaker] Managing resources - classes
Hi All,
I am new in Pacemaker and having some problems with it.
My task is to configure heartbeat with two nodes and make one shell script
managed by it (or by pacemaker). The fact is: Pacemaker needs to manage this
shell script and make it run again if it sttoped.
I have installed heartbeat and Pacemaker and it seems that they are correctly
installed. At least I can see that both nodes are configured and with a online
status (crm status). But something strange is happening when I try crm ra
classes command. Nothing is showed. I dont know if some configuration is
missing. Is ther any problem with it? How can I have a list of classes?
In addition, how colud be a primitive to manage this shell script?
I would be grateful even if you point me some books, tutorials, manuals, etc...
I have searched a lot but could not find very good information about it.
Thanks,
Alan
