Eep, no failover should have occurred if you don't have fencing. > In Rhcs V3. it reboot fail node automatically without hardware power switch > > So, Have anyway to reboot failed node(network problem or server problem) > without use hardware power switch to make failnode to clean state again ? You need fencing hardware with RHCS4/RHEL4. I'd check ebay if you're not looking to spend a lot, you can get a WTI NPS115 for pretty cheap nowadays (under $100!). You can run with manual fencing, but no automatic recovery will occur, and this isn't a supported solution. -- Lon -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
