      There is one SR (ISO repos) that is shown offline but it is definitely online. I cannot repair or remove it.

      If i try to remove it, xoa starts "Async.PBD.unplug" in the tasks, but after few minutes/hours the task is gone and the SR is still there.

        That's because XAPI tries to unplug something you can't reach. Try with xe pbd-unplug force=true uuid=<UUID>.

          With this command i get (copy-pasted the uuid)
          The uuid you supplied was invalid.
          type: PBD
          uuid: UUID from SR

          Edit: xe task-list = empty

            What UUID are you using? My command was an example.

              I used this UUID respectively this command "xe pbd-unplug force=true uuid=b7b541e7-a44d-61b7-0db4-55a0f9ce78bb"

                And are you sure this UUID was the PBD UUID? (and not the SR UUID)

                  It was the false UUID....sorry! With the correct UUID it took about 3-4 hours and I ended up with this error:

                  xe pbd-unplug force=true uuid=44e9e1b7-5a7e-8e95-c5f1-edeebbc6863c
                  Another operation involving the object is currently in progress
                  class: SR
                  object: b7b541e7-a44d-61b7-0db4-55a0f9ce78bb (NAS2 ISO)
                  <extra>: plug

                    I edited your post to use markdown syntax 🙂

                    Anyway, you have something blocking the mount or umount, try to find the process, kill him. Alternatively, lazy umount.

                    That's what happening when you remove physically a SR before removing it from XAPI 😞

                      Many thanks for the help!!

                      Unfortunately I still could not solve the problem. Is it advisable to restart the host completely?

                      EDIT: Found this in the xensource.log:
                      PBD.destroy locking failed: caught transient failure OTHER_OPERATION_IN_PROGRESS: [ SR; OpaqueRef:d4815da4-f7ca-40b0-ab21-f67411a7abf3; plug ]

                      I already checked all SRs and PBDs but the UUID can not be found.

                      Could this be the problem?

                        Yes, there's a lock somewhere on the missing SR.

                          But how can i find and break the lock?

                          I searched every uuid (pbd, sr, vdi, host, ..) but cannot find anything.

                            No I mean in the dom0 system, check if there's specific process on the mountpoint

                              @gawlo to check mountpoint as olivier suggested

                              lsof +D /mountpoint

                                  @gawlo if you can reboot then you can try, but if the process is started after the reboot, it will still block your mountpoint.

                                  And the mountpoint is the result of this command

                                  xe pbd-param-get param-name=device-config uuid=44e9e1b7-5a7e-8e95-c5f1-edeebbc6863c

                                    I tried to get the mountpoint with the command from @tony but the result always was "The uuid you supplied was invalid."

                                    To get a new/live log i restarted the toolstack (the 100th time..) and now everything is working again. I dont know why but okay..

                                    Thank you very, very much @olivierlambert and @tony for your help!!!!
