红帽全球峰会22.6.2. 为动态创建的 OpenStack PV 配置区域标签
管理员可以为动态创建的 OpenStack PV 配置区域标签。如果 OpenStack Cinder 区域名称与计算区域名称不匹配，则此选项很有用，例如，如果只有一个 Cinder 区域，并且有多个计算区域。管理员可以动态创建 Cinder 卷，然后检查标签。
查看 PV 的区标签：
oc get pv --show-labels
# oc get pv --show-labels
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE LABELS
pvc-1faa6f93-64ac-11e8-930c-fa163e3c373c 1Gi RWO Delete Bound openshift-node/pvc1 standard 12s failure-domain.beta.kubernetes.io/zone=nova
默认设置是 enabled。使用 oc get pv --show-labels 命令返回 failure-domain.beta.kubernetes.io/zone=nova 标签。
要禁用区标签，请通过添加以下内容更新 openstack.conf 文件：
[BlockStorage] ignore-volume-az = yes
[BlockStorage]
ignore-volume-az = yes重启 master 服务后创建的 PV 将不会具有 zone 标签。
