Redhat cluster Vs Gluster Vs DRBD

view full story

http://serverfault.com – I am getting my hand to setup redhat cluster on Centos 6 using its python GUI interface LUCI. As of now I am following Redhat documentation to set this up. I was wondering if anyone knows how to setup Virtual machines on cluster with shared resources on two hosts. (Either as HA-LVM resource or GFS resource) Currently I achieve this with DRBD. By running the virtual machine on DRBD resource setup across two hosts as primary and secondary. In case of failure I just need to upgrade the secondary to primary Manually (I am not using heartbeat/Pacemaker) and start the virtual machine. Last but (HowTos)
