8.5.

先决条件

    • hw_scsi_model=virtio-scsi
    • hw_disk_bus=scsi

流程

  1. (overcloud)$ openstack volume list

  2. $ openstack server add volume <instance> <volume>

    • 注意

      Multiattach volumes are only supported starting with compute API version 2.60. (HTTP 400) (Request-ID: req-3a969c31-e360-4c79-a403-75cc6053c9e5)

      $ openstack --os-compute-api-version 2.72 server add volume <instance> <volume>
    提示

  3. $ openstack volume show <volume>
