Hi, I’m building a two node cluster (three nodes in future),
and I’d like to prevent nodes from start whenever other nodes does not
join the cluster. However, I don’t like the idea of fencing a node is not
part of the cluster in an uncontrolled way when other node is forming a new
cluster (let’s say, while patching the system). I’ve found a nice
way to do so by configuring clean_start to 0 and post_join_delay to “-1".
With this configuration fence daemon will not try to fence the nodes out of the
cluster and will wait until the rest of nodes join the cluster in this status: [root@jimenez1 admin]# group_tool type level name id
state fence 0 default 00010001
JOIN_START_WAIT [1] dlm 1 rgmanager 00020001
none [1] [root@jimenez1 admin]# clustat Cluster Status for ext_test @ Tue Dec 29 15:01:54

problem. I’d like to be able to manually start the cluster in that node
by means of a command or something like that. I’ve seen in the past I
could use fence_tool with –c option to leave the JOIN_START_WAIT
status and let the cluster start with only one node. However, this
options does not seem to be available in my version (I’m using RHEL 5.3)
and cman version cman-2.0.115-1.el5_4.9. With this configuration, is there any way to start the
cluster manually in only one node without reconfiguring the cluster? Is there
any other configuration that allows me to have the same functionality? Best regards, Alfredo Moralejo F. Hoffmann-La Roche Ltd. Global Informatics Group Infrastructure Phone: +34 91 305 97 87 Confidentiality Note:
