Hi, i'd like to establish a 2 Node-Cluster. My OS will be SLES 11 and HAE. My services will run in VM's using KVM. I will install the VM's in LV's, one LV for one VM. The LV's will be plain partitions, having no filesystem. I have read this is quicker with KVM than installing a VM in a LV with filesystem. My LV's will reside on a FC SAN. Both nodes have access to the SAN. For the LV's, i will use cLVM.
My questions are: - let's assume that, due to an error, a VM will run on both nodes. Does cLVM prevent that both VM's have simultaneously access to the corresponding LV ? So that the data is not destroyed. - Is it possible that some VM's run on the first node and other VM's run on the second node simultaneously ? - what do you think about my setup ?
