HDD の増設

なぜか 1TB の HDD が放置状態だったので、第三世代 LinkStation ハックキットで Debian 化した LS-QL に増設することにする。
LS-QL の RAID の操作なんて、もうすっかり忘れている。。。。

パーティションの確認

増設する 1TB HDD WD10EADS のパーティションがどうなっているかを見るために、 USB で LS-QL に接続する。

fdisk で作ったパーティションなので、要らない。

qube:~# fdisk /dev/sdb

The number of cylinders for this disk is set to 121601.
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)

sdb も msdos なので、そのままにしておく。いいのか？？？

パーティションを切る

parted -s /dev/sdb mkpart primary ext3 0 1028M とかしてパーティションを切っていこうと思ったのだが、確か標準ファームにパーティションを切るスクリプトがあるはず。

ごそごそ

/initrd/usr/local/bin/libbuffalo_bin create_partition /dev/sdb
を実行すればできそう。
やってみる。

qube:~# cd /initrd/usr/local/bin/
qube:/initrd/usr/local/bin# ./libbuffalo_bin create_partition /dev/sdb
./libbuffalo_bin: error while loading shared libraries: libbuffalo_bin.so.1: cannot open shared object file: No such file or directory

chroot してやってみる。

qube:/initrd/usr/local/bin# chroot /initrd/
qube:/# /usr/local/bin/libbuffalo_bin create_partition /dev/sdb
grep_file:file /proc/partitions open fail.

/proc がないと言われたので、/proc をマウント

qube:/# mount /proc
qube:/#

再実行

qube:/# /usr/local/bin/libbuffalo_bin create_partition /dev/sdb

OK!

/dev/sdb6 のマウント

データ領域の /dev/sdb6 を /mnt/disk2 にマウントする。

まず、fstab の修正

qube:~# vi /etc/fstab
	:
	:
qube:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
#                                
/dev/md1        /               xfs     defaults,noatime                0 0
proc            /proc           proc    defaults                        0 0
/dev/md10       swap            swap    defaults                        0 0
/dev/md0        /boot           ext3    defaults,noatime                0 0
/dev/sda6       /mnt/disk1      xfs     defaults,noatime                0 0
/dev/sdb6       /mnt/disk2      xfs     defaults,noatime                0 0
qube:~#

最終行を追加。

続いて、マウントポイントを作成。

qube:~# mkdir /mnt/disk2
mkdir: cannot create directory `/mnt/disk2': File exists
qube:~# ls /mnt
disk1  disk2  share
qube:~#

あれ？ある。

マウントする。

qube:~# mount /mnt/disk2/
qube:~# df
