一 格式化实战
[root@localhost ~]# ls -l /dev/sdb*
brw-rw---- 1 root disk 8, 16 Jul 22 09:10 /dev/sdb
brw-rw---- 1 root disk 8, 17 Jul 22 09:10 /dev/sdb1
brw-rw---- 1 root disk 8, 18 Jul 22 09:10 /dev/sdb2
brw-rw---- 1 root disk 8, 19 Jul 22 09:10 /dev/sdb3
brw-rw---- 1 root disk 8, 21 Jul 22 09:10 /dev/sdb5
brw-rw---- 1 root disk 8, 22 Jul 22 09:10 /dev/sdb6

二 挂载实战
[root@localhost ~]# mkdir -p /mnt/sdb1
[root@localhost ~]# mount /dev/sdb1 /mnt/sdb1
[root@localhost ~]# umount /mnt/sdb1/
如果要使得挂载永久生效
[root@localhost ~]# vim /etc/fstab
