      Without fence mechanism, the cluster won't be aware there a node
      down, and then you can continue writing modifications in both

                          <div>Hi<br>
                            <br>
                          </div>
                          Today I have deploy a tree node plus storage
                          scenario in a lab.<br>
                        </div>
                        First at all, I image that I need configure
                        fence device, as docs demand...<br>
                      </div>
                      So, I decide to use a MAnaged Switch (DLikn
                      DES-3028).<br>
                    </div>
                    But, I realize that even without fence configuratio
                    HA works properly and NICE, I might add..<br>
                    <br>
                  </div>
