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

/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
