ovirt_disk: Fault reason is "Operation Failed". Fault detail is "[Internal Engine Error]". HTTP response code is 400.

[mattpoel]

SUMMARY

We have a playbook to add / remove direct LUNs to VMs in ovirt. Since an update of ovirt, this process is no longer properly working and fails with an internal error without details:

"msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Internal Engine Error]\". HTTP response code is 400."

ovirt_disk is updated to the latest version (or the whole ovirt-ansible-collection to be specific).

COMPONENT NAME

ovirt.ovirt.ovirt_disk

STEPS TO REPRODUCE

  - name: "ovirt / OLVM -> Add Direct LUN (not activated)"
    delegate_to: localhost
    ovirt.ovirt.ovirt_disk:
      auth: "{{ ovirt_auth }}"
      name: "testdbcl_RDATA02"
      host: "tdbkvm"
      interface: virtio_scsi
      vm_name: "testdbcl1"
      propagate_errors: True
      shareable: True
      activate: no
      scsi_passthrough: disabled
      logical_unit:
        id: "36000144000000010f04ca7574b4d02b9"
        storage_type: fcp

EXPECTED RESULTS

LUN gets configured as a direct LUN and attached to the VM.

ACTUAL RESULTS

ovirt_disk creates the disk, but it doesn't get attached to the VM. Following error is raised:

[mattpoel]

oVirt / OLVM version is 4.3.10.4-1.0.22.el7

[mattpoel]

Actually the disk even gets assigned and it is unclear why this internal engine error is raised:

[MightyS33]

Same/similar issue here. ovirt_disk creates the disk, but i get the following error:

It seems that there are problems with synchronizing the LUNs. In the events of the engine the message appears: Direct LUN synchronization started

Here is my ansible task:

- name: Create Direct LUN Disk
  ovirt.ovirt.ovirt_disk:
    auth: "{{ ovirt_auth }}"
    name: "{{ vm_name }}_fc1"
    host: {{ direct_lun_host }}
