大佬们求助，硬盘没法格式化/dev/sda1 is apparently in use by the system; will not make a filesystem here!

束手无策了

[busier]

确定该盘不再使用，并取消了自动挂载

否则不要继续下面的操作


以 root 身份执行命令 wipefs -a -f /dev/sda1

重启后再格式化

@busier woc 可以了，感谢大佬

[busier]

还有忘了说了 确定他不是 lvm zfs 或 btrfs 的一部分

Fdisk -l 只看了分区类型 这只是分区表的设定值 没啥用

用 blkid 看下分区文件系统是啥

@busier 刚刚按你说的重启后可以格式化了，非常感谢！！！

做过 zfs 吗？
