问题1：
Provider页面上传后，刷新了页面、或者切换页面导致传输中断，一直queued状态，上传时不要做刷新和切换页面操作
问题2：
上传时空间不足，保存镜像失败，状态为saving，可以通过df -h查看卷空间状态
问题3：
glance存储在ceph，上传时/var/log/glance/api.log报服务重启，状态为saving，已知故障，需要更改参数：参见：https://dev.zte.com.cn/topic/#/57358
1）：pcs resource show glance_fs
如果 OCF_CHECK_LEVEL 不是10 ，则执行步骤2的命令
2）：pcs resource update glance_fs op monitor interval=20s OCF_CHECK_LEVEL=10
interval=20s（这里的值和第一步查看到的值保持一致）
问题4：
glance存储在swift上，需要集群节点大于一半在线，不然会导致上传镜像失败，状态为queued，日志如下：
/var/log/glance/api.log报 ERROR glance.common.wsgi Got error from Swift: put_object('glance', '3cc12767-6e97-4eb2-85ea-1d69b69d0261', ...) failure and no ability to reset contents for reupload..
swift日志报：/var/log/swift/swift.log
