      Have you checked if Thin Provisioning is on? I don't think that it works with lvm SR

      It can't be. Thin provisioning in XS is ext3 and thick is LVM. It's not that they are doing thin on ext3, it's that the terms are used interchangeably. Thin is a code name for ext3, thick is a code name for LVM. The act of mounting LVM makes it thick.

      Makes no sense...
      Why does/would the XS installer GUI even let one select Thin prov on a 14+TB SR

      Yeah that is what I was saying. Dumb.

      Unless we are missing something.

        The file system LVM doesn't support thin provisioning, simply.

        EXT does however, so you'd assume that by selecting enable thing provisioning, you'd be setting the local storage to be configured for EXT.

        Yet if it's over 2TB is size it doesn't mount.

        That's my guess

          LVM definitely can't be thin provisioned? I don't know myself, but Googled...

            I'll play with my lab at some point and see if I can get this going.

                So the individual 8TB drives are all listed as available targets, but selecting the thin provisioning seems to do nothing.

                It still configures it as LVM, and thick.

                For testing, go ahead and follow through with the process, then once the install is complete run

                 xe sr-list uuid=<any 8tb uuid> params=all

                  Will do.
                  I added 4x 8TB virtual drives + 1x 64GB (for o/s)

                    How about the message: "One SR will created that spans the selected disks"?

                      @FATeknollogee I'm not certain, I've never presented more than a single disk to be used for the local storage.

                      If it create a single array across of the disks then it's doing some sort of RAID setup. Which would be bad, since you generally want your array managed by the controller

                        Unless of course you're using software raid.

                        But this was previously setup inside of XS, not during installation. (there is a guide around here somewhere with software raid and XS 6.5)

                          That message seems to imply that XS would create some type of "span" across the 4 disks I selected.

                            I assume some sort of RAID setup (span is just a non-scary word for it)

                              I think it just spans it. No RAID.

                                Ran that cmd as root: result - "No such file or directory"

                                  @FATeknollogee You put in a proper SR uuid, correct?

                                      You don't have remote access (or out of band access) to the host?

                                      You can do this directly via XC and the console connection.

                                          Is this the right cmd to find UUID?

                                            Good, just making sure you weren't walking to the server...
