Oh yes you can. If you want to use the "cib" based "crmd" style
configuration, you will have to. Why do you think you can not?
You cannot change the facts by asking the same question again.
But if it helps to get the message across, please, anyone that wants to,
feel free to add
"Confirmed by"
to this thread.

If you, for what ever (non technical) reason you think you are stuck
with heartbeat 2.1.x, stay with haresources, possibly add "mon" into
your setup, and hope for the best.
If you want to go "cib" and "crm", you absolutely have to use Pacemaker.
Whether you then use Pacemaker on top of heartbeat (3.0.x) or corosync
is an other decision, and unaffected by this.
But please accept that Pacemaker is the very same CRMD (cluster resource
manager daemon) that came with heartbeat 2.1.x, only four (4!) years of
bug fixing and development later.
So if you insist on using some known to be buggy 4 year old piece of
software, just because one component of it now goes by a different name,
I'm sorry, but you should not expect much help.
I think we told you that already?
Still, you asked to be pointed to documentation.
There is the section "Documentation For Older Releases"
http://www.clusterlabs.org/wiki/Documentation
Which links to some relevant docs about 2.1.x.
Just in case you absolutely love to hurt yourself
;-)
