centos5.6挂载6T的空间

最近上了台存储设备，6T空间，准备开始对大容量存储做分区以及格式化挂载
由于MBR分区支持最大容量只有2T 如果超过2T的话 就要使用gpt分区

首先使用parted命令把硬盘转换成gpt分区
——————————————————————
[root@ ~]#parted /dev/sdb
GNU Parted 1.8
Using /dev/sdb
Welcome to GNU Parted! Type ‘help’ to view a list of commands.
(parted)

由MBR转为GPT磁盘
—————————————————————————————————————-
(parted)mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No?Yes
(parted)

设定你要做的分区的type以及size(根据实际情况来) 0 ，-1表示起点容量和终点容量，其差就是分区容量,单位是M mkpart primary 0 -1 表示划分全部容量
—————————————————————————————————————-

(parted)mkpart primary 0 -1
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel?Ignore
(parted)
(parted)
(parted)p
Model: Adaptec RAID 5 (scsi)
disk /dev/sdb: 6TB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags
1 17.4kB 28.0TB 6TB primary
(parted) quit
@R_667_4045@ion: You may need to update /etc/fstab.

已经分区完毕 接下来开始格式化硬盘并挂载
———————————————————————————————————————?
[root@ ~]# mkfs.ext3 /dev/sdb1
[root@ ~]# mount /dev/sdb1 /data

至此大功告成!
[root@ ~]$ df -lTh
Filesystem Type Size Used Avail Use% Mounted on
