            @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.

                >xe vm-list name-label=test05

                  @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.

                        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.

                                    This is a supercool and amazing thing. Coming from Proxmox with Ceph I really feel this was a missing piece. I want to migrate my whole homelab to this!

                                    I've been playing around with it a fair bit, and it works well, but when it came to enabling HA I ran into trouble. Is XOSTOR not a valid shared storage target to enable HA on?

                                    Having multiple shared storages (NFS/CIFS etc) in production is a given to put backups and whatnot on, but I thought it was weird that I couldn't use XOSTOR storage to enable HA.

                                      I'm also really hoping that XOSTOR works well and also feel like this is something XCP-NG really needs. I've tried other distributed storage solutions, notably GlusterFS but never found anything that really works 100% when outages occur.

                                      Note I plan to use XOSTOR just for VM disks and any data they use - not for the HA share and not for backups. My logic is that:

                                      • backups should not be anywhere near XCP-NG and should be isolated software and hardware - and hopefully location wise.
                                      • HA share needs to survive a issue where XCP-NG HA fails; if XCP-NG quorum is not working then XOSTOR (Linstor) quorum may be affected in a similar way - so I keep my HA share on a reliable NFS share. Note that in testing I found if the HA share is not available for a while that XCP-NG stays running OK (just don't make any configuration changes until HA share is back).

                                        @yrrips I fixed several problems with the HA and the linstor driver. I don't know what's your sm version, but I updated it few weeks ago (current: sm-2.30.6-1.2.0.linstor.1.xcpng8.2.x86_64). Could you give me more details?

                                          I have been waiting for this for some time. after XOSAN didn't really work for me, but neither did OVH's SAN offering.

                                          Is there a documentation page to look at rather than going through the thread?

                                          In the absense of that is there a minumum recommanded host count?

                                          Would love to give this a try but would mean playing with production VMs!

                                            Hello @markhewitt1978 !

                                            • First post is a complete guide šŸ™‚
                                            • 3 hosts is fine, no less. No problem with more.

                                            We are still investigating a bug we discovered recently, so I wouldn't play in production right now (except if you are very confident and you have a lot of backup).
