force to add a node

Hi,

Openais - Pacemaker last version.
I modified the IP of a node and now it appears
always offline even if openais is running.
is there a way to force to turn on a node ?
sorry for my stupid question..

Did you supply a node id in openais.conf?
If not, that might confuse the cluster.

Otherwise, did you make sure the bindnetaddr is correct in openais.conf?

Hi Andrew,

> Did you supply a node id in openais.conf?
no, it's commented as it's written as optional

> Otherwise, did you make sure the bindnetaddr is correct in openais.conf?
yes, I use the main IP of every node, not the network class.

so put off all nodes and openais, removed all cib files (unless cib.xml)
restarted them and now works well.

do I need to assign a node id on every node manually ?

Thanks

Franck

yes, it is. but if you don't specify one its generated from the ip address.
thus when you changed the ip address the nodeid also changed.

that would have confused things - although 1.0.6 should be able to handle it ok.

thats the bit that would have fixed it, stopping the cluster
everywhere (so that the other nodes forgot about the old nodeid)

You didn't notice that Fedora-10 is no longer supported by Fedora? :-)

Perhaps. If you plan on changing the IP address a lot.
