      First tests with XOSAN with newly created VMs have been good.

      I'm now trying to migrate some existing VMs from NFS (TrueNAS) to XOSAN to test "active" VMs.

      With the VM running - pressing the Migrate VDI button on the Disks tab, pauses the VM as expected but when the VM restarts the VDI is still on the original disk. The VDI has not been migrated to XOSAN.

      If I first stop the VM and then press the Migrate VDI button on the Disks tab, I then do get an error.

      vdi.migrate

      Exporting the VDI from NFS and (re)importing as a VM on XOSTOR does work.

      I'm guessing this is not a problem with XOSTOR specifically but with XO or NFS, still I would like to work out what is causing migration and how to fix it?

      Also I have noticed that the underlying volume on XOSTOR/linstor that was created and started to be populated does get cleaned up when the migrate fails.

      This is using XO from the sources - updated fairly recently (commit 8ed84) and XO server 5.92.0.

        It could be interesting to understand why the migration failed the first time. Is there absolutely no error during this first migration?

          @olivierlambert Thanks for the prompt response.

          I am pretty sure there was no error reported but as I cleared down the logs when I retried from on export/import I can't be 100% sure.

          So I tested migration on another VM to try and replicate this and this time migration worked OK.

          The only difference I can think of is that the failure occurred on a VM created quite a time ago - whilst the working VM had been created recently.

          I will do a few more tests and see if I can replicate this again.

            Okay great šŸ™‚ If you can reproduce, that would be even better to try to do the migration with xe CLI, this way we remove more moving pieces in the middle šŸ™‚

              @olivierlambert Sorry, took some time to get around to this. But trying to migrate a VDI from an NFS store to XOSTOR is still failing most of the time. This is a VM that was created some time ago - it I do the same with the VDI of a a recently created VM the migration seems to work OK.

              Error code: SR_BACKEND_FAILURE_46

              Running this I see the VM pause as expected for a few minutes and then it just starts up again. VM is still running with no issues - it just did not move the VDI.

              What is the resource with UUID 735fc2d7-f1f0-4cc6-9d35-xxxxxxxxec6c that it is trying to find? That UUID does not match the VDI.

              The VDI must be OK as the VM is still up and running with no errors.

              As this is probably not an XOSTOR issue - should I raise a new topic for this?

                It's hard to tell. If you can migrate between non-XOSTOR SRs and see if you reproduce, then it's another issue. If it's only happening when using XOSTOR in the loop, then it's relevant here šŸ™‚

                        @geoffbland Can you execute this command on the other hosts please?

                        ls -l /dev/drbd/by-res/xcp-volume-75c11231-0fb8-4b40-9e2e-a0665bb758c0/0
                        

                        Also I don't have all the info in your previous log, can you send me the previous SMlog files? (Using private message if you want. šŸ™‚ )

                            It seems like xe may be getting mixed up between where a host is running and where the XOSTOR storage is held.
                            Apologies if I have misunderstood and done something wrong here - but I think this migration should have worked.
                            I created a new VM on one of my hosts XCPNG05 using XOSTOR as the VDI RS. I can see that the linstore volumes are on hosts XCPNG01, XCPNG03 and XCPNG05.
                            XCPNG05 is an Intel server, XCPNG01 and XCPNG03 are AMD. The VM is running on XCPNG05.
                            Now when I try to migrate the VM's VDI from XOSTOR onto a local VDI on the same host the VM is currently running on I get a warning about incompatible CPUs.

                            To replicate the issue:

                            Create new VM test05 on XOSTOR.
                            VM is created on host XCPNG05.

                              @geoffbland Thank you, so ok the VDI is still here on all hosts.

                              You can try to check the status of the VDH like the smapi using:

                              /usr/bin/vhd-util query --debug -vsfp -n /dev/drbd/by-res/xcp-volume-75c11231-0fb8-4b40-9e2e-a0665bb758c0/0
                              

                              If you have this problem on many hosts, I suspect a problem with DRBD, so maybe there is a useful info in daemon.log and/or kern.log.

                                  @geoffbland Okay so it's probably not related to the driver itself, I will take a look to the logs after reception. šŸ™‚

                                    Failure trying to revert a VM to a snapshot with XOSTOR.

                                    Created a VM with main VDI on XOSTOR (24GB) and with 6 disks each also on XOSTOR (2GB each).
                                    All is running OK.
                                    Now create a snapshot of the VM - this takes quite a while but does eventually succeed.
                                    Now using XO (from sources) click the "Revert VM to this snapshot". This errors and the VM stops.

                                    vm.revert
                                    {

                                    From the VM disks tab if I try to Attach the disks, two of the disks created on XOSTOR are missing (data1 and data4).

                                    Finally if I go to storage and bring up the XOSTOR storage and then press "Rescan all disks" I get this error:

                                      Okay so it's probably not related to the driver itself, I will take a look to the logs after reception. šŸ™‚

                                      Did you get chance to look at the logs I sent?

                                        @geoffbland So, I didn't notice useful info outside of:

                                        FIXME drbd_a_xcp-volu[24302] op clear, bitmap locked for 'set_n_write sync_handshake' by drbd_r_xcp-volu[24231]
                                        ...
                                        FIXME drbd_a_xcp-volu[24328] op clear, bitmap locked for 'demote' by drbd_w_xcp-volu[24188]
                                        

                                        Like I said in my e-mail, maybe there are more details in another log file. I hope. šŸ™‚

                                          In the end I realised I was more trying to "use" XOSTOR whilst testing rather than properly test it. So I decided to rip it all down and start again and retest it again - this time properly recording each step so any issues can be replicated. I will let you know how this goes.

                                            @ronan-a Could you please take a look at this issue I raised elsewhere on the forums.

                                            I am currently unable to create new VMs, getting a No such Tapdisk error - checking down the stack trace - it seems to be coming from a get() call in /opt/xensource/sm/blktap2.py and this code seems to have been changed in a XOSTOR release from 24th May.
