The above messages suggest that the web server file system requires the vg_apache volume group and lv_apache logical volume to be active, but they aren't. You may want to look at the ocf:heartbeat:LVM and ocf:heartbeat:LVM-activate resource agents to bring these dependencies into the cluster. The ocf:heartbeat:iSCSILogicalUnit and ocf:heartbeat:iSCSITarget agents may also be of interest. > > Daemon Status: > corosync: active/enabled > pacemaker: active/enabled > pcsd: active/enabled > > > And checked the iSCSI Shared Storage.
