再使用fdisk -l命令查看分区情况.
[root@g11-64-1 ~]# fdisk -l
Disk /dev/hda: 21.4 GB, 21474836480 bytes

显示/dev/hdb上有一个hdb1分区,为linux格式.
分区后,需要对这个分区进行格式化.
[root@g11-64-1 ~]# mkfs.ext3 /dev/hdb1

将新建分区挂在到/mnt/hdb1上.
[root@g11-64-1 ~]# mkdir /mnt/hdb1
[root@g11-64-1 ~]# mount /dev/hdb1 /mnt/hdb1
[root@g11-64-1 ~]# df -h

[root@g11-64-1 ~]#
hdb1已挂载到/mnt/hdb1上,剩余空间为9.2G.
在此分区上创建文件.
[root@g11-64-1 ~]# cd /mnt/hdb1
[root@g11-64-1 hdb1]# ls > a
[root@g11-64-1 hdb1]# ls -hl

[root@g11-64-1 hdb1]#
卸载hdb1分区.
[root@g11-64-1 hdb1]# cd
[root@g11-64-1 ~]# umount /mnt/hdb1
[root@g11-64-1 ~]# df -h
