I try to make a iSCSI Target on CentOS 6.4 with DRBD, Pacemaker, Open-iSCSI and LVM2. Now i need to prepare the HA iSCSI Target configuration on the crm shell, but if i enter the configure mode, there's a error message:

[root@centos ~]# crm
crm(live)# configure
ERROR: running cibadmin -Q1: Could not establish cib_rw connection: Connection refused (111)
Signon to CIB failed: Transport endpoint is not connected
Init failed, could not perform requested operations

Because crm is not included in the newest pacemaker-cli package, i added this OpenSUSE Repo, before I installed the package crmsh.x86_64.

cat /var/log/messages | grep corosync:

corosync[1052]:   [MAIN  ] Compatibility mode set to whitetank. Using V1 and V2 of the synchronization engine.
corosync[1052]:   [TOTEM ] A processor joined or left the membership and a new membership was formed.

cat /var/log/messages | grep pacemaker:

pacemakerd[1251]:   error: find_corosync_variant: Corosync is running, but Pacemaker could not find the CMAN or Pacemaker plugin loaded
pacemakerd[1251]:   notice: get_cluster_type: This installation does not support the ´(null)´ cluster infrastructure: terminating.

Please advise, thanks!

In RHEL5 you needed to run the cman service too: "service cman start". Don't know about RHEL6. –  AndreasM Sep 27 '13 at 10:04
    
can you show your cluster configuration? have you tried this guide clusterlabs.org/quickstart-redhat.html ? –  c4f4t0r 2 days ago
