fdisk 问题。
操作系统:Linux CentOS 7
我在 USB 驱动器上使用了 fdisk。它挂起了,我无法将其关闭或退出。
另一个问题是,从那时起,为了解决这个问题,我物理上移除了 /dev/ 中显示的其他 USB 驱动器。然而,即使不再物理连接,它们仍然显示在 /dev/ 中。
这是 lsblk(我从这个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
我根据朋友为我格式化另一个 USB 驱动器(完全相同的 USB 驱动器类型)时所做的笔记做出了以下选择。目的是将其格式化为 ext4。
以下是一组选项(加粗):
[root@linux18 ~]# fdisk /dev/sdf

这看起来与您所面临的问题非常类似:https://access.redhat.com/solutions/369623
也许可以尝试# dmsetup remove
使用手册页中的某些标志(--force --deferred --retry
)

对我来说,我需要强制重新扫描连接到系统的磁盘,如所述这里,例如:
echo "- - -" >> /sys/class/scsi_host/host_0/scan
