      Is there a way to enable this on an SR without using the xe cli? Can we specify this as an option during SR creation from XO? Or did this become the normal way to create an SR? I have both 8.2.x and 8.3, Truenas Scale and NFS shares on both.

        @Greg_E It is a separate SR type that you can select when you create a SR in Xen Orchestra.

        It's also just local SR. For NFS you still use the NFS storage driver.

          Thanks, I was wondering if that was the case from reading the other threads.

            @dthenot Are multiple SR-s with type=largeblock supported on the same host?

              I don't see any reason it couldn't, but I prefer @dthenot to answer 🙂

                NVMe drives attached to the PERC H965i are identified as SCSI disks in the operating system
                OS exposes a 4kn nvme device on /dev/disk/by-id/scsi-36f4ee0807844d90068121b9321711e05

                Below is a log of creating a type=largeblock SR on latest XCP-ng 8.2

                It takes about 10 minutes and some errors but it does successfully create the SR and we are able to use it.
                Are all these errors expected and we can trust it's working normally?

                Console:

                # xe sr-create host-uuid=383399d1-b304-48db-ad4b-bc8fe8b56f89 type=largeblock name-label="Local Main Name storage" device-config:device=/dev/disk/by-id/scsi-36f4ee0807844d90068121b9321711e05

                      Sorry, I missed the first ping.

                      May  2 08:32:24 a1 SM: [18985] ***** Long LVM call of 'vgs' took 43.6255850792
                      

                      That would explain why it took a long time to create. 43 seconds for a call to vgs.
                      Can you try to do a vgs call yourself on your host?
                      Does it take a long time?

                      This exception is "normal":

                      It's the garbage collector trying to run on the SR but it is in the process of attaching.
                      It's weird though because it's the call to sr_attach that launched the GC.
                      Does the GC run normally on this SR on next attempts?

                      Otherwise, I don't see anything worrying the logs you shared.
                      It should be safe to use 🙂

                        Maybe this call was somehow in a locked state during the 512 SR create

                          @yllar Maybe it was because of the loopdevice not being completely created indeed.
                          No error for this GC run.

                          Everything should be ok then 🙂
