红帽全球峰会6.5. Ceph 卷实用程序
ceph-volume lvm batch 命令失败，并显示混合设备类型
当使用 lvm batch 子命令过滤设备时，ceph-volume 命令不会返回预期的返回代码，当 Ceph OSD 策略发生变化时。这会导致 ceph-ansible 任务失败。在这个版本中，ceph-volume 命令在 Ceph OSD 策略更改时返回正确的状态代码，允许 ceph-ansible 正确检查新的 Ceph OSD 是否可以添加或不添加新的 Ceph OSD。
ceph-volume 命令将逻辑卷视为原始设备
ceph-volume 命令将逻辑卷视为原始设备，这会导致 add-osds.yml playbook 失败。这不允许额外的 Ceph OSD 添加到存储集群中。在这个版本中，ceph-volume 中修复了一个代码 bug，因此它可以正确处理逻辑卷，而 add-osds.yml playbook 则可用于将 Ceph OSD 添加到存储集群中。
