  当磁盘损坏或者文件系统损坏，系统无法正常挂载时如何处理该问题。

实操演示

• 修改/etc/fstab文件，添加一个错误的挂在信息

[root@sinfotek ~]# vim /etc/fstab 


# 
# /etc/fstab
# Created by anaconda on Thu Nov 10 09:52:37 2022
#
# Accessible filesystems, by reference, are maintained under '/dev/disk/'.
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info.
#
# After editing this file, run 'systemctl daemon-reload' to update systemd
# units generated from this file.
