                                  Do not use sharding and stripe

                                </div>
                                a) It is not recommended and there is no
                                point in using both. Using sharding
                                alone on your volume should work fine.<br>
                              </div>
                              b) Nobody tested it.<br>
                            </div>
                            c) Like Niels said, stripe feature is
                            virtually deprecated.<br>
                            <br>
                          </div>
                          I would suggest that you create an nx3 volume
                          where n is the number of distribute subvols
                          you prefer, enable group virt options on it,
                          and enable sharding on it,<br>
                          set the shard-block-size that you feel
                          appropriate and then just start off with VM
                          image creation etc.<br>

                                                      <pre>Couple of things to note before you do that:
1. Most of the bug fixes in sharding have gone into 3.7.8. So it is advised
that you use 3.7.8 or above.
2. When you enable sharding on a volume, already existing files in the
volume do not get sharded. Only the files that are newly created from the
time sharding is enabled will.
    If you do want to shard the existing files, then you would need to cp
them to a temp name within the volume, and then rename them back to the
original file name.
