        This is the second time in two days I've read about XS console - what is the XS console? Do you mean, does Citrix mean, the XS host? Calling it a console is so..... weird.

        But hey, they call the virtual disks that are attached to VMs VDIs - so what do I know?

        PIPE DOWN! Do you want your servers hearing you and crashing again?????

          Was redacting that address really necessary? 🙂

                Psst - give greenshot a try - it's a free screen capture utility that has cool bluring features for bluring whatever you don't want read.

                          In the vein of EXT vs LVM and LVM "partitions"....

                          In the directions, it says to find the SCSI ID of the device/partition where the SR data is stored.

                          Here is my list.

                          Because XS by default uses the entire SR storage device as LVM, with an EXT parition, is that why you'd select the whole device here? (I selected ata-KINGSTON_KW-S34480-4W1_50026B7256062EA5 (/dev/sdb) from my list.)

                            @BRRABill It wan'ts the SCSI ID, because that ID shouldn't ever change. That same drive might become sdd if you add/remove drives, but the SCSI ID will remain the same.

                              What I mean is, it says drive or partition.

                              So if the entire drive is using a LVM "partition" than it doesn't show as a partition. You would just give it the entire drive SCSI ID.

                              But, say it was on /sdc5 ... you'd give it the SCSI ID for that partition?

                              Still just shoring up my EXT/LVM knowledge.

                                /dev/sdc is a drive
                                /dev/sdc5 is a partition on that drive

                                If you put LVM on /dev/sdc there is no partitions and LVM uses the entire drive.
                                If you put LVM on /dev/sdc5 there is a partition and LVM uses the entire partition. That partition MIGHT use the entire drive or not.

                                  What I think is still getting me is that the SR is really EXT on the LVM controlled drive.

                                  So why wouldn't you give it the SCSI ID of that, instead of the entire drive?

                                  What if there was more than one LV on the LVM controlled drive, and each had EXT?

                                  Or am I still confusing partitions and file systems?

                                    SCSI ID is about a block device. Filesystem is file, not block. The filesystem is what converts a block device into a file device. If that's helpful.

                                      It's because it wants control and it needs to know what underlying block device you want to hand to it, not one that you've virtualized on top.

                                        It's because it wants control and it needs to know what underlying block device you want to hand to it, not one that you've virtualized on top.

                                        So what would happen if there were indeed more LVs on that block device?

                                          ah, I see the question... you are wondering if you resize will XS complain because it is expecting to control the entire thing? that's a good point.

                                          That would suggest that partitioning manually would be better, which sucks as an answer.

                                            Just a general question for Linux knowledge.

                                            But yes, that is my question exactly for XS usage.

                                            It seems like it wants the entire block device, wouldn't you agree?
