I have a 2 node setup (with quorum disk), redhat 6.5 & a luci mgmt console.
Everything has been configured and we’re doing failover tests now.
Couple of questions I have :
· When I simulate a complete power failure of a servers pdu’s (no more access to idrac fencing or APC PDU fencing) I can see that the fencing of that node who was running the application fails ß I noticed unless fencing returns an OK I’m stuck and my application won’t start on my 2nd node. Which is ok I guess, because no fencing could mean there is still I/O on my san.
Clustat also shows on the active node that the 1st node is still running the application.
How can I intervene manually, so as to force a start of the application on the node that is still alive ?
Is there a way to tell the cluster, don’t take into account node 1 anymore and don’t try to fence anymore, just start the application on the node that is still ok ?
I can’t possibly wait until power returns to that server. Downtime could be too long.
· If I tell a node to leave the cluster in Luci, I would like it to remain a non-cluster member after the reboot of that node. It rejoins the cluster automatically after a reboot. Any way to prevent this ?
