1. 현재 연결된 기기 확인

(아래는 31.7GB(/dev/mmcblk0)과 1000.2 GB(/dev/sda)의 2개의 외장기기 확인됨

   /dev/mmcblk0는 /dev/mmcblk0p1과 /dev/mmcblk0p2의 2개 파티션으로 구성 되어 있고

          /dev/sda는 /dev/sda1로 파티션 1개로 구성되어 있음)

2. device에 mount할 폴더 생성

root@slave1:~# mkdir /app
root@slave1:~# mkdir /app/usb
root@slave1:~# mkdir /app/usb2
root@slave1:~# mkdir /app/hdd

 

3. hdd는 인식가능하게 파티션을 생성해야함..

root@slave1:/# fdisk /dev/sda

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0xb092454e.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.


Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)


The device presents a logical sector size that is smaller than

the physical sector size. Aligning to a physical sector (or optimal

I/O) size boundary is recommended, or performance may be impacted.


Command (m for help): o

5. device와 폴더 연결(mount)

root@slave1:/# mount /dev/sda1 /app/hdd

 

6. 자동 mount설정

 vi /etc/fstab에 아래의 내용을 추가한다.
