Linux mount掛載磁盤報錯 mount: wrong fs type, bad option, bad superblock on /dev/vdb
Linux掛載磁盤報如下錯誤：
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
安裝nfs
運行fdisk -l命令查看實例上的數據盤，發現/dev/vdb未被使用
[root@localhost ~]# fdisk -l

創建一個ext4文件系統
[root@localhost ~]# mkfs -t ext4 /dev/vdb1
運行mount /dev/vdb1 /mnt命令掛載文件系統
[root@localhost ~]# mount /dev/vdb1 /mnt
如果運行df -Th命令後出現新建文件系統的信息，表示文件系統掛載成功
[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
設置自動掛載
[root@localhost ~]# lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
vda
└─vda1 ext4 1ae5f12f-79c1-47d4-************* /
vdb
└─vdb1 ext4 1e3cb065-e1ad-4ee1-************* /mnt
通過修改/etc/fstab實現自動掛載，添加如下配置即可
UUID=1e3cb065-e1ad-4ee1-******* /mnt ext4 defaults 0 0
添加完成後，執行mount -a 即可生效
