8.3. Create a GFS2 Filesystem

8.3.1. Preparation

Before we do anything to the existing partition, we need to make sure it is unmounted. We do this by telling the cluster to stop the WebFS resource. This will ensure that other resources (in our case, Apache) using WebFS are not only stopped, but stopped in the correct order.
# crm_resource --resource WebFS --set-parameter target-role --meta --parameter-value Stopped
# crm_mon
