[Tip] parted(2TB 이상 Disk 파티션)

[root@:/]  parted /dev/sdb

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?

parted: invalid token:  gpt

Yes/No?  yes                                                               

New disk label type?  [msdos]?  gpt                                        

(parted)  mkpart                                                           

Partition name?  []?   파티션 네임으로 중요하지 않습니다. 그냥 엔터                                             

File system type?  [ext2]?  [엔터]                                                

Start?  0                                                                   

End?  2GB or 100%  단일 파티션으로 사용할것이고, 2GB 디스크이기 때문에 시작= 0 ~ 끝 2GB로 합니다.

## 또는 mkpart primary 0 -1로 해도 된다. 이것은 처음부터 끝까지 잡겠다는 것이다.

 

(parted)  quit

Information: Don't forget to update /etc/fstab, if necessary.  

 

gpt 설정이 끝났습니다. 이것은 fdisk /dev/sdb 대신 parted로 mbr이 아닌 gpt를 생성한 것이죠.
