Bigdata, Hadoop ecosystem, Semantic IoT등의 프로젝트를 진행중에 습득한 내용을 정리하는 곳입니다.
필요한 분을 위해서 공개하고 있습니다.
문의사항은 gooper@gooper.com로 메일을
보내주세요.
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

4. 작성된 파티션을 사용하기 위해 파일시스템을 생성한다.

5. device와 폴더 연결(mount)
root@slave1:/# mount /dev/sda1 /app/hdd
6. 자동 mount설정
vi /etc/fstab에 아래의 내용을 추가한다.
/dev/sda1 /app/hdd ext4 defaults 0 0
