      @olivierlambert Hello Olivier,

      the error on the red notification is : unknown error from the peer:

      887454aa-57ca-4fcd-a0ae-c03da457d93b-image.png

      and the complete error log:

      vm.start
      {
        "id": "95991d36-a94c-4efe-62e0-3d15b2245bce",
        "bypassMacAddressesCheck": false,
        "force": false
      }
      {
        "errors": [
          "Host 1: VM_REQUIRES_SR(OpaqueRef:7371d453-759a-4870-934c-9a1b13fa40a7, OpaqueRef:8a929bf4-9b17-4bce-ab59-e2d5665baa0b)",
          "Host 2: HOST_NOT_LIVE()"
        ],
        "message": "",
        "name": "Error",
        "stack": "Error: 
          at Xapi._startVm (file:///opt/xo/xo-builds/xen-orchestra-202205201634/packages/xo-server/src/xapi/index.mjs:990:15)
          at Xapi.startVm (file:///opt/xo/xo-builds/xen-orchestra-202205201634/packages/xo-server/src/xapi/index.mjs:1026:7)

      }
      

      the storage is exactly as it was, same name , same type, same paths on NFS.

        This means a SR used in this VM can't be reach on host 2. You should boot it.

          @olivierlambert this is by mistake, i used to have a host 2 also in the pool that i don't use. now i removed it by the pool.

          error log: still same without the line of host 2 missing.

          vm.start
          {
            "id": "95991d36-a94c-4efe-62e0-3d15b2245bce",

            Do you have an ISO plugged in this VM by any chance?

                  I would check if you don't have a stalled NFS connection somewhere. Do you have a working df -h output on your host? Anything special on dmesg?

                  One way or another, XAPI still think there's no access to those shares. You can also do a xe-toolstack-restart and try again.

                    @olivierlambert df -h
                    looks like it mounts correctly the specific NFS

                    e2fdebae-0fca-498b-9e97-b8f5a8c44b2f-image.png

                    dmesg nothing special, toolstack restart i did also from Xen Orchestra , i guess is executing the same command.

                      Do a xe vm-disk-list uuid=<VM UUID>, and then for each SR, double check the PBD is connected.

                        @olivierlambert said in XCP-ng host not seeing storage after unmount / mount:

                        xe vm-disk-list uuid=<VM UUID>

                        Hello Sir, i have SSH on the host and run the command , using the uuid of the VM we are trying to start.

                          Okay sqo both disks are on VM_space_H1. Do a xe sr-param-list uuid=<SR UUID>, get the PBDs and for each do a xe pbd-param-list uuid=<PBD UUID> and paste the result 🙂
