Ah. Does manual migration through virsh work rather than clusvcadm?
If it does -- I'd put rgmanager into some extra logging by editing
/etc/init.d/rgmanager with RGMGR_OPTS="-dddd" under the RGMGRD part.
Then restart rgmanager and check logs for more info after trying clusvcadm
-M again. (add debug to host / target servers and see if you catch anything
new)

Good luck
Henry

virsh migrate --live <guest> qemu+ssh://2nd node/system

Migrates the guest to the other cluster member w/no objections.

Added "-dddd" to /etc/sysconfig/rgmanager, restarted rgmanager and 
verified that rgmanager is running w/the option set. I do not see any 
increase in logging from the default setting of "-d"?

Attempted another clusvcadm -M <vm service> -m <2nd cluster node>, and 
I see nothing in either of the /var/log/cluster/rgmanager.log files. 
Not even that the operation was attempted?!?

Is migration supported on KVM? I've tried it with Xen and works fine. The only
gotcha was that the `nx' flag on the CPU needed to be available.

hello all.
I installed two redhat hat 5.2 servers with redhat cluster suite option.
When i want to create a cluster with luci i got an error message: An error occurred when trying to contact any of the nodes in the rh-cluster cluster.
Do you have any ideas?
thanks.
Ludovic

hello,

is /etc/hosts configured properly? try with IP address instead of the
hostname.

Yes, KVM supports both migration & live migration and with KVM-8* and 
libvirt 0.6.4 you can use "virsh migrate --live" to move running 
guests between nodes (live migrate). This fact is reflected in the 
upstream (git repo) version of the vm.sh resource script, but it seems 
like something - rgmanager itself? - is blocking it from even trying.

Hi all,

I'm configuring a FailOver-cluster with CentOS 5.3 on two Dell PowerEdge
2950 with DRAC5 cards. The basic configuration with
system-config-cluster worked fine after enabling telnet on the DRACs and
I got the cluster running. Then I switched to ssh by manually editing
the cluster.conf file, since system-config-cluster is not aware of
fence_drac5. Unfortunately now the cluster.conf file is not readable
anymore by system-config-cluster. I still want to use sys-con-clu, since
there is still much to configure  (services, failover-domains,....).
Except of using telnet and fence_drac until the end of the configuration
process, I have no other idea how to manage that. DOes anyone know how
to include fence_drac5 and the secure="1" attribute in cluster.conf and
still using sys-con-clu?

All best

Mario

P.S. Is secure="1" in the right place?

cluster.conf:
