本地盘数据状态说明

操作	本地盘数据状态	说明
OS重启控制台重启/强制重启	保留	本地盘存储卷保留，数据保留
OS关机控制台停止/强制停止	保留	本地盘存储卷保留，数据保留
控制台终止（VM释放）	擦除	本地盘存储卷擦除，数据不保留

1、本地盘上的数据仅在关联的实例生命周期内保留，本地盘所关联的实例重启和关机，本地盘上的数据保留

2、当实例执行释放行为时，会擦除本地盘中的应用程序和数据，建议您在应用层做好业务高可用，并及时备份和复制本地盘中的重要数据

3、i1 实例的数据盘是本地盘，有丢失数据的风险（比如 NVMe SSD 故障或宿主机宕机时），如果您的应用不能做到数据可靠性的架构，我们强烈建议您使用云盘搭建您的实例。
