                                <div>Hi, I'm trying to realize a cluster
                                  with 2 nodes that manages a volume
                                  group.<br>
                                </div>
                                Basically I have a san connected to both
                                nodes that exposes 1 lun. So both nodes
                                have a disk /dev/sdb. From one node I
                                did:<br>
                              </div>
                              fdisk /dev/sdb  <- Create a partition
                              with type = 8e (LVM)<br>
                            </div>
                            pvcreate /dev/sdb1<br>
                          </div>
                          vgcreate myvg<br>
                          <br>
                        </div>
                        then<br>
                        <br>
                      </div>
                      pcs resource create halvm LVM volgrpname=myvg
                      exclusive=true <br>
                      <br>
                    </div>
                    Last command fails with an error: "LVM: myvg did not
                    activate correctly"<br>
                    <br>
                  </div>
                  Reading /usr/lib/ocf/resource.d/<wbr>heartbeat/LVM, this
                  happens because it seems that I need at least one
                  logical volume inside the volume group before create
                  the resource. Is this correct?<br>

    Yes, you need to create pv, vg before you use cluster to manager it.<span class=""><br>

    Normally, clvm is used in cluster with shared storage as:<br>
