Linux mount挂载磁盘报错 mount: wrong fs type, bad option, bad superblock on /dev/vdb

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

[root@localhost ~]# fdisk -l

创建一个ext4文件系统

[root@localhost ~]# mkfs -t ext4 /dev/vdb1

运行mount /dev/vdb1 /mnt命令挂载文件系统

[root@localhost ~]# 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

[root@localhost ~]# df -Th
Filesystem     Type   Size  Used Avail Use% Mounted on
/dev/vda1      ext4    40G   35G  2.8G  93% /
tmpfs          tmpfs  3.9G     0  3.9G   0% /dev/shm
/dev/vdb1      ext4    59G   1G   58G  99% /mnt

设置自动挂载

[root@localhost ~]# 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
