Forget cLVM or any cluster filesystem. Use regular LVM and ext3 or XFS or whathaveyou. The build a resource group with ocf:heartbeat:LVM, ocf:heartbeat:Filesystem, ocf:heartbeat:IPaddr2, and ocf:heartbeat:apache. Make sure you configure STONITH so you can arbitrate access to shared storage. Cheers, Florian
