Hi, For a two-node cluster, what are the best STONITH devices? Currently I am using Dell's iDrac for STONITH device. It works pretty well. However the biggest problem for iDrac or any other lights-out devices is that they share power supply with hosts machines.
Once an active machine lost its power completely, you want to fail-over to the backup-node in your cluster. But with iDrac as your STONITH device you can not, because the STONITH resource on backup node will run into error (fail to connect to STONITH device, it's out of power too) , and refuse to start any resources. I was wondering what kind of STONITH devices everybody is using to solve this problem. And how much are they? Actually Pacemaker's page have a link talking about this: http://www.clusterlabs.org/doc/crm_fencing.html It suggests UPS (Uninterruptible Power Supply) as well as PDU (Power Distribution Unit). Anybody used them before? How well are they integrated with Heartbeat? What are the pros and cons?
