fdisk未完成并挂在USB驱动器上

fdisk问题。

操作系统：Linux centos 7

我在USB驱动器上使用了fdisk。它已挂起，我无法杀死它或摆脱它。

从那以后，作为一个附加问题，在尝试解决此问题时，我物理上删除了显示在/ dev /中的其他USB驱动器。但是，即使不再物理连接，它们仍显示在/ dev /中。

这是lsblk（我已从此列表中删除了列出的其他设备）lsblk

NAME                    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sdf                       8:80   0   1.8T  0 disk 
└─sdf1                    8:81   0   1.8T  0 part 
sr0                      11:0    1  1024M  0 rom  

我按照朋友为我格式化另一个USB驱动器（相同的USB驱动器类型）时所做的注释进行了以下选择。目的是将其格式化为ext4。

以下是一组选项（有插图）：

[root@linux18 ~]# fdisk /dev/sdf

^[[6~

^C^[[5~

也许尝试# dmsetup remove使用手册页（--force --deferred --retry）中的一些标志
