I setup a 3-node cluster on RHEL4U5, with GULM. There are one failover domain, one resource and one service, just for testing.
I found clustat always report rgmanger is running after cluster is started.
With the configuration with DLM, clustat report correctly.
node4 is lock server, and all nodes report the same inaccurate information.
Here is commands and report:
node4:~# service ccsd start
Starting ccsd: [ OK ]
node4:~# service lock_gulmd start
Starting lock_gulmd: [ OK ]
node4:~# clustat
msg_open: No route to host

node4 Online, Local, rgmanager
node3 Online, rgmanager
node2 Online, rgmanager

-----------------------------
Please note, first/seond clustat actually report an error: msg_open: No route to host
When the cluster is DLM, there is another msg printed:
Resource Group Manager not running; no servie information available.
check rgmanager status, it is stopped. but report said rgmanager running on all nodes, and groupmember is set on.
is it supposed to be that?
Any hint are very welcome.
Thanks,
Siman
