      Hi,

      I think it's not related to Xen Orchestra but XCP-ng. Can you display the SR object via xe sr-param-list uuid=<SR UUID>?

        Yes, I can. Here it is:

        I just reinstalled xoce completely, added servers and the problem persists.

          There's no PBDs in there. Just forget the SR and recreate it.

          xe sr-forget uuid=861221a3-24a6-a43c-176d-2158059cd64e

            Well, it helped with SR, but not with VM creation. I created new SR. It created ok. I see ISOs there. It's mounted, I can read files from NFS:

            10.1.0.222:/nas/xoce/iso 5719538688 17259520 5702279168   1% /run/sr-mount/b9af5c9d-0baf-8fe1-f325-3fed4351097b

            But if I try to create VM pink box with "unknown error from the peer" happenes and new entry to the log is added:

            INTERNAL_ERROR((Failure "Expected string, got 'N'"))

This is a XenServer/XCP-ng error

            BTW, I can't remove newly created SR. Any attempts to delete it immediately results in "unknown error" and SR_NOT_EMPTY() in log.

              Please display the SR record for the one you freshly created.

              You can't remove a SR if there's disks in it, you need to forget it instead.

                  This sounds OK to me. I think your issue is related to something else, please display the VM record (xe vm-param-list uuid=<VM UUID>

                    @olivierlambert How can I show that param if I'm getting error during my attempts to create a VM?

                      So the VM isn't created at all? You really need to give us more info. What template are you using? Is it working if you don't add an ISO?

                          Yes, this error:

                          INTERNAL_ERROR((Failure "Expected string, got 'N'"))

This is a XenServer/XCP-ng error

                          happens when I click create.

                                You have to investigate on your XCP-ng host, there's obviously a problem in there.

                                See https://xcp-ng.org/docs/troubleshooting.html

                                I would suggest to restart the toolstack too.

                                  @olivierlambert This problem is common for all 3 servers, i did not touch other two hosts at all for a while. I see some strange error appear in xensource.log after VM creation attempt:

                                    You have duplicates in XAPI DB, that's not normal 🤔

                                    It's coming from a template I assume.

                                      @olivierlambert But templates are stock templates, no? It does not matter what template I choose, it fails anyway.

                                      How to fix them?

                                        I have no context on what you did on those hosts previously, so it's hard to answer what to do to assist.

                                        I don't know what could trigger that in the first place 🤔

                                          @olivierlambert I did not do anything on these hosts, except occasional yum update. Frankly, i did not touch this setup for a while and it worked a month or two ago ok.

                                          I'm kinda surprised that all 3 servers do the same. One of them wasn't touched at all except yum update since it worked ok.

                                            It's normal you have the problem on the whole pool/all hosts, because the XAPI database is shared with all hosts.

                                            I would search for duplicate keys for platform record on all your existing VMs.
