- linux虚拟机上中挂载光驱报"mount:youmustspecifythefilesystemtype"错误处理
1、环境说明
宿主主机操作系统：Windows 7
虚拟机软件：VMware Ware
虚拟操作系统：linux 6.3 （文件系统EXT4）
2、错误现象
| [[email protected] ~]# mount /dev/cdrom /mnt/ mount: you must specify the filesystem type |
3、原因分析
（1）由于是虚拟机，所以最先怀疑的是虚拟机的设备中的“CD/DVD”未设置所引起，但是检查其“Connection”在Use ISOimage file上有指定ISO文件，排除此原因所引起
（2）查发现“CD/DVD”的Device status中的“Connected”未打勾，将此项打勾后，重启，可以正常挂载光驱
4、“CD/DVD”的Device status中的“Connected”勾选后mount光驱
