1. fdisk에서 2TB 이상의 파티션을 지원하지 못하므로, 2TB 이상 파티션을 구성하기 위해서는 다음과 같은 방법에 따라 작업을 해줘야 한다.

2. 우선 fdisk를 이용해 현재 전체 하드 용량을 체크한다.

[root@storage ~]# fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 2993.9 GB, 2993996955648 bytes
255 heads, 63 sectors/track, 363999 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

3. parted 명령으로 파티셔닝 한다.

[root@storage ~]# part
parted partprobe partx
[root@storage ~]# parted /dev/sdb --> 파티셔닝 할 스토리지 지정.
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(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
New disk label type? [gpt]? gpt
(parted) print --> 하드 정보 확인.

Model: INTEL SRCSATAWB (scsi)
Disk /dev/sdb: 2994GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags

(parted) gpt
check NUMBER do a simple check on the file system
cp [FROM-DEVICE] FROM-NUMBER TO-NUMBER copy file system to another partition
help [COMMAND] prints general help, or help on COMMAND
mklabel,mktable LABEL-TYPE create a new disklabel (partition table)

print [free|NUMBER|all] display the partition table, a partition, or all devices
quit exit program
rescue START END rescue a lost partition near START and END
resize NUMBER START END resize partition NUMBER and its file system
rm NUMBER delete partition NUMBER
select DEVICE choose the device to edit
set NUMBER FLAG STATE change the FLAG on partition NUMBER
toggle [NUMBER [FLAG]] toggle the state of FLAG on partition NUMBER
unit UNIT set the default unit to UNIT
version displays the current version of GNU Parted and copyright information
(parted) mkpart

Partition name? []? --> 엔터
File system type? [ext2]? --> 엔터
Start? 0 --> 시작점을 지정해 준다. 0으로 지정.
End? 3.0TB --> 용량을 확인한 뒤 마지막 지점을 지정한다.(2994GB=3.0TB)
(parted) q --> 빠져나가기.
Information: Don't forget to update /etc/fstab, if necessary.

4. 정상적으로 잡혀있는지 /proc/partitions 로 확인한다.

[root@storage ~]# cat /proc/partitions
major minor #blocks name

8 0 78150744 sda
8 1 104391 sda1
8 2 8193150 sda2
8 3 2048287 sda3
8 4 1 sda4
8 5 8193118 sda5
8 6 2096451 sda6
8 7 1020096 sda7
8 8 56492541 sda8
8 16 2923825152 sdb
8 17 2923825118 sdb1 --> 정상적임을 확인.

5. /dev/sdb1 을 ext3 방식으로 포맷.

[root@storage ~]# mkfs.ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
warning: 503 blocks unused.

This filesystem will be automatically checked every 32 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

6. 포맷 완료된 sdb1 을 마운트 한다.

[root@storage ~]# cd /
[root@storage /]# mkdir data
[root@storage /]# mount /dev/sdb1 /data
[root@storage /]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda3 ext3 1.9G 357M 1.5G 20% /
/dev/sda8 ext3 53G 181M 50G 1% /home
/dev/sda7 ext3 965M 18M 898M 2% /tmp
/dev/sda2 ext3 7.6G 1.9G 5.4G 26% /usr
/dev/sda5 ext3 7.6G 201M 7.0G 3% /var
/dev/sda1 ext3 99M 17M 77M 18% /boot
tmpfs tmpfs 1003M 0 1003M 0% /dev/shm
/dev/sdb1 ext3 2.7T 202M 2.6T 1% /data --> 정상적으로 마운트 된 것을 확인할 수 있다.

7. fdisk 로 실제 파티셔닝된 정보를 확인한다.

[root@storage /]# fdisk -l
