[Pacemaker] [Ocfs2-users] Error building ocfs2-tools

[Tim Serong]

Hi Nick,

It might not be obvious, but IMO this probably belongs back on the 
Pacemaker list (CC'd).

When in doubt, use the source...

ocfs2-tools' ocfs2_controld/pacemaker.c:165[1] says:

   send_ais_text(crm_class_notify, "true", TRUE, NULL, crm_msg_ais);

pacemaker's lib/common/ais.c:327[2] says:

   switch(cluster_type) {
     case pcmk_cluster_classic_ais:
       ...
       break;
     case pcmk_cluster_corosync:
     case pcmk_cluster_cman:
       transport = "cpg";
       CRM_CHECK(dest != crm_msg_ais, rc = CS_ERR_MESSAGE_ERROR;
         goto bail);

So you're hitting that assert, because Pacemaker sees "cluster_type" as 
either "pcmk_cluster_corosync" or "pcmk_cluster_cman".

If Pacemaker saw cluster_type as "pcmk_cluster_classic_ais", it would 
work fine.

 From memory, you're running Pacemaker under CMAN, somehow. 
Unfortunately I have no idea what you need to do to reconfigure it so 
that ocfs2_controld works, or even if it will work in that environment, 
but the above code is the source of your trouble.

Regards,

Tim
