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
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | 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
[root@localhost ~]# fdisk -l Disk /dev/vda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00020f78 Device Boot Start End Blocks Id System /dev/vda1 * 1 5222 41940992 83 Linux Disk /dev/vdb: 64.4 GB, 64424509440 bytes 16 heads, 63 sectors/track, 124830 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x41398dd0
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，添加如下配置即可文章来源：https://www.toymoban.com/news/detail-735325.html
vi /etc/fstab
UUID=1e3cb065-e1ad-4ee1-******* /mnt ext4 defaults 0 0
添加完成后，执行mount -a 即可生效文章来源地址https://www.toymoban.com/news/detail-735325.html
