NAS化

Sambaを導入してNAS化する。
ただし、現在以下のようなマウント状態なので、以前のように/mnt/disk1にマウントしたパーティションだけをNASで使うようするため、パーティション変更から始める。
その方が使用量の確認がしやすいから、というのが一番の理由。
KUROBOX-PRO:~# df
Filesystem     1K-blocks    Used Available Use% Mounted on
rootfs         239758888 1037776 226542016   1% /
udev               10240       0     10240   0% /dev
tmpfs              12560     116     12444   1% /run
/dev/sda2      239758888 1037776 226542016   1% /
tmpfs               5120       0      5120   0% /run/lock
tmpfs              98220       0     98220   0% /run/shm
/dev/sda1         233191   12534    208216   6% /boot

パーティション分割

/dev/sda2の240GBほどのルート領域を20GBに変更して残りを/dev/sdxとして/mnt/disk1にマウントするようにしたいが、玄箱PROに接続したままの状態ではパーティション変更が難しいのでいったん玄箱PROから物理的に外して別環境で作業する。
今回使ったのはGParted。
Linux環境が手元になかったのでGParted Live CD/USB/HD/PXE Bootable ImageをダウンロードしてDVDに焼き、このDVDでブートして作業した。キャプチャとか取っていないので詳細は割愛。
外したHDDはUSBで接続できる変換ケーブルを使用

Command (m for help): q
/dev/sda4が新しく切り出したNAS用の領域、これを/mnt/disk1にマウントすれば以前と同じように使える。
自動的にマウントされるようにfstabに追記しておく
