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


3. parted 명령으로 파티셔닝 한다.

[root@localhost ~]# 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  
(parted) print   <-- 하드 정보를 확인합니다.

Model: AMCC 9650SE-8LP DISK (scsi)
Disk /dev/sdb: 3500GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start  End  Size  File system  Name  Flags

(parted) mkpart
Partition name?  []?  엔터
File system type?  [ext2]?  엔터
Start? 0  <-- Start 지점은 0으로 설정
End? 3.5TB  <-- 위에서 확인된 전체 용량을 적어준다.
(parted) q


4. 실제 잡혀 있는지 /proc/partitions 를 확인한다.

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

   8     0   78150744 sda
   8     1      80293 sda1
   8     2    2096482 sda2
   8     3    2096482 sda3
   8     4          1 sda4
   8     5   10241406 sda5
   8     6    6144831 sda6
   8     7    4096543 sda7
   8     8     329301 sda8
   8     9   53062663 sda9
   8    16 3417895936 sdb
   8    17 3417895902 sdb1

5. /dev/sdb1 을 ext3 방식으로 포멧한다.

[root@localhost ~]#  mkfs.ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
427245568 inodes, 854473975 blocks
42723698 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
26077 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
        4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968,
        102400000, 214990848, 512000000, 550731776, 644972544

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 20 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

6. 포멧 완료된 sdb1 을 마운트 한다.

[root@localhost /]# mkdir data
[root@localhost /]# mount /dev/sdb1 /data
[root@localhost /]# df -Th
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda2     ext3    2.0G  496M  1.4G  27% /
/dev/sda1     ext3     76M   15M   58M  21% /boot
tmpfs        tmpfs    2.0G     0  2.0G   0% /dev/shm
/dev/sda9     ext3     50G  180M   47G   1% /home
/dev/sda8     ext3    312M   11M  286M   4% /tmp
/dev/sda7     ext3    3.8G  1.8G  1.9G  48% /usr
/dev/sda5     ext3    9.5G  253M  8.8G   3% /usr/local
/dev/sda6     ext3    5.7G  580M  4.9G  11% /var
/dev/sdb1     ext3    3.2T  199M  3.0T   1% /data    <-- 3.2T 정상적으로 마운트가 된 것을 확인할 수 있다.


7. fdisk 로 실제 파티셔닝된 정보를 확인한다.

[root@localhost /]# fdisk -l
