当前基本设备 UUID：与存储的 UUID 不匹配：

Question

Docker 出现故障，所以我重新启动了服务，但服务没有启动，出现以下错误：

error msg="[graphdriver] prior storage driver \"devicemapper\" failed: devmapper: Base Device UUID and Filesystem verification failed: devmapper: Current Base Device UUID: does not match with stored UUID:696f3567-83d7-48d7-9675-688e8543534b. Possibly using a different thin pool than last invocation"

我了解此问题的解决方法是删除 /var/lib/docker 的内容，然后重新启动。

在不删除容器数据或图像的情况下，是否有针对此问题的任何解决方案或变通方法？

当我在调试模式下启动 docker 时，我得到以下信息：

您好，我遇到了同样的问题，解决方案是使用 blkid 查看 /dev/loop0 上的实际 UUID

示例 /dev/loop0: UUID="12345678-e192-482e-81c6-9f703db548b6" TYPE="xfs"

基本设备在文件(/var/lib/docker/devicemapper/metadata/deviceset-metadata)中配置：

{"next_device_id":1,"BaseDeviceUUID":"**OLD-UUID**","BaseDeviceFilesystem":"xfs"}

就改变它吧！

然后再次启动引擎...您的图像和容器现在可能已经回到您身边了！
