1、查看分区
# fdisk -l //查看现有硬盘及分区 /dev/sdb就是新的3TB硬盘 。
Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 2610 20860402+ 8e Linux LVM
Disk /dev/sdb: 3324.3 GB, 3324304687104 bytes
255 heads, 63 sectors/track, 404157 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
2、分区
# parted /dev/sdb //为/dev/sdb硬盘分区
GNU Parted 1.8.1
使用 /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt //硬盘转换为GPT
(parted) mkpart //创建分区
分区名称？ []? //直接回车
文件系统类型？ [ext2]? //直接回车，也可以输入ext3或者xfs等格式
起始点？ 0 //分区开始
结束点？ -1 //分区结束 -1为全部硬盘空间
(parted) p //查看分区结果
Model: VMware, VMware Virtual S (scsi)

3、格式化
# mkfs -t ext4 /dev/sdb1

4、挂载
# mkdir /test //创建目录 /test。
# mount /dev/sdb1 /test //把分区挂载到 /test上。
# df -h //查看已挂载的目录。
