软路由， 爱快虚拟机安装OPENWRT+4G空间用一段没问题，重装以后出现磁盘问题，怎样解决？谢谢！


磁盘错误信息，
GPT PMBR size mismatch (3687486 != 3687488) will be corrected by write.
The backup GPT table is corrupt, but the primary appears OK, so that will be used.
The backup GPT table is not on the end of the device. This problem will be corrected by write.

GPT PMBR 大小不匹配 (3687486 != 3687488) 将被写入更正。
备份 GPT 表已损坏，但主表显示正常，因此将使用该表。
备份 GPT 表不在设备的末端。此问题将通过写入来纠正。

格式化以后，在容器中安装以后看不到文件显示文件存在换个硬盘安装也一样的状态换个版本系统也一样

用DG试试呗

测试一下有没有part命令，如图输入  linux提示WARNING: GPT (GUID Partition Table) 3 如果没有parted命令那就是没有安装呢，
