Linux mount挂载磁盘报错 mount: wrong fs type, bad option, bad superblock on /dev/vdb
Linux挂载磁盘报如下错误：
mount: wrong fs type, bad option, bad superblock on 192.168.0.68:/mnt,
missing codepage or helper program, or other error
(forseveral filesystems (. nfs, cifs) you might
need a/sbin/ program)
In some cases useful infois found in syslog - trydmesg|tail or so
安装nfs
yum install nfs-utils
运行fdisk -l命令查看实例上的数据盘，发现/dev/vdb未被使用
[[email protected] ~]# fdisk -l

创建一个ext4文件系统
[[email protected] ~]# mkfs -t ext4 /dev/vdb1
运行mount /dev/vdb1 /mnt命令挂载文件系统
[[email protected] ~]# mount /dev/vdb1 /mnt
如果运行df -Th命令后出现新建文件系统的信息，表示文件系统挂载成功
[[email protected] ~]# df -Th

设置自动挂载
[[email protected] ~]# lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
vda
└─vda1 ext4 1ae5f12f-79c1-47d4-************* /vdb
└─vdb1 ext4 1e3cb065-e1ad-4ee1-************* /mnt
通过修改/etc/fstab实现自动挂载，添加如下配置即可
vi /etc/fstab
UUID=1e3cb065-e1ad-4ee1-******* /mnt ext4 defaults 0 0
添加完成后，执行mount -a 即可生效
