Hello all
Thank you Dejan and Dr. Schwartzkopff
But please bear with me because I'm still suffering a problem. Here is what
I did:
# wget -O /etc/yum.repos.d/clusterlabs.repo
http://clusterlabs.org/rpm/epel-5/clusterlabs.repo
# yum install pacemaker pacemaker-libs cluster-glue cluster-glue-libs
resource-agents heartbeat

Attempting connection to the cluster....
# strace -o hb-again crm_mon -i5
// the file is attached
// I didn't find perl on the system , so I installed it
# yum install perl
// indeed, i believe the error is at around 92% of the strace output file
when it attempts to:
connect(3, {sa_family=AF_FILE, path="/var/run/crm/cib_ro"...}, 110) = -1
ENOENT (No such file or directory)
close(3) = 0
socket(PF_FILE, SOCK_STREAM, 0) = 3
fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
connect(3, {sa_family=AF_FILE, path="/var/run/crm/cib_callback"...}, 110) =
-1 ENOENT (No such file or directory)
I can't understand why it can not run :( ..
Version 1.0.5 of pace maker and openais 0.80.5 worked like a charm on the
same nodes.
Now I have to shift to heartbeat because of unicast directive. Please help!
Thank you in advance
