mkfs.ext4 /dev/vdb
挂载
mount /dev/vdb /mnt
设置开机默认挂载
[root@localhost ~]# blkid /dev/sdb
/dev/sdb: UUID="b8c4a45f-ed74-3089-fcdb-0273de904d6d" TYPE="ext4"
[root@localhost ~]# vim /etc/fstab
在最后一行增加如下信息
UUID=b8c4a45f-ed74-3089-fcdb-0273de904d6d /image ext4 defaults 1 2
/dev/vdb is apparently in use by the system; will not make a filesystem here!
