      Well, it does look like I messed up while adding the local storage. I'll just reinstall after I clear another problem child off my bench.

      What was messed up during the installation?

        Nothing during the installation. I'm thinking I added the local storage wrong and couldn't find how to undo what I did in an hour yesterday, it's faster to just wipe and redo it.

          @travisdh1 Is this on an array larger than 2TB? I'm assuming so, right?

            Yes, 6 2TB drives in RAID 10.

              @travisdh1 Okay cool, so a 6TB array.

              Did you try to use the array directly from the installation, or did you skip using any local storage, and wanted to configure it manually?

                I waited and did it manually. Software RAID, so I don't think the install script gives you the choice of using it. If it does I can give that a shot this time.

                  Oh, yeah software array you have to configure inside of XS, so you won't be able to set it up from the installer.

                    Why did you go Software RAID?

                    But that does explain why you didn't see the ext3 issue Dustin was seeing during his install.

                    Do you think your lvm issue was because of something you did incorrectly when trying to attach it, not something that was wrong with lvm?

                      That's what I had been wondering, you had left the XS standard support system and are doing it manually, so a bunch of manual work is expected.

                        You can't get lvm during install, at least with v6.5. There is no option to choose the setup type of the SR.

                          Yes there is. We tell people to pick ext3 most of the time as the only thing you need to know during the setup. It's labeled "thin provisioned."

                            Yep. Basically, the T3500 replaces a low power box that was only storage space. With the T3500, it has enough horsepower to cover other services when the one real server goes down. So why not have that security blanket is how my logic is working.

                                  When would you NOT want to thin provision?

                                  And are you saying if it is over 2TB you cannot thin provision?

                                    Right, there is a known problem that makes XO slow because of what it uses under the hood. Use Veeam and it will be fast, I'm sure. It's not an XS speed issue. It's a XAPI call speed issue that is leveraged by XO.

                                    It's not just XO. A lot of the people on the XS bug tracker aren't using XO. It's just a bug in exporting/importing.

                                      Yes, XS has an import/export slowness. Not a backup one.

                                        That's the issue, thin provisioning is limited currently to 2TB or smaller volumes (VHDs.)

                                            When would you NOT want to thin provision?

                                            And are you saying if it is over 2TB you cannot thin provision?

                                            That's the issue, thin provisioning is limited currently to 2TB or smaller volumes (VHDs.)

                                            Wait, is it 2 TB volumes as in ext3 partitions or is it 2 TV VHDs?
