Hi,<br>
<br>
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.<br>
My LV's will reside on a FC SAN. Both nodes have access to the SAN. For the LV's, i will use cLVM.<br>
<br>
My questions are:<br>
<br>
- 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.<br>
<br>
- Is it possible that some VM's run on the first node and other VM's run on the second node simultaneously ?<br>
<br>
- what do you think about my setup ?<br>
<br>
<br>
<br>
