Oracle Linux 4 새로넣은 디스크 mount 시키기

OS환경 : Oracle Linux 4.8 (64bit)

 

방법 : Oracle Linux 4 새로넣은 디스크 mount 시키기

기존 환경에 20gb 크기의 디스크를 추가한뒤 기동한 상태

 

 

fdisk -l 로 디스크 확인

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

20GB 디스크를 추가한 상태 

/dev/sdb 부분 확인

 

 

fdisk 명령으로 파티션 설정

# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
 
 
The number of cylinders for this disk is set to 2610.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
