Filesystem features の変更

Filesystem features を変更する

バックアップ

いきなり変更して起動しなくなっても困るので、まずは Link Station の HDD の hda1 ( / ) のバックアップを取る
Link Station の HDD を実験機に接続し、

intel# cd /home/ls
intel# mount /dev/hdc1 root
intel# tar zcvf LinkStation_Vine-2.6_040115.tar.gz root
intel# umount root

Filesystem features の変更

とりあえず、/dev/hdc1 ( / ) だけを変更する。
hdc3 をバックアップできるだけの容量はないし、 hdc3 なら、Link Station に接続した状態でも変更できるので。

intel# tune2fs -O ^dir_index /dev/hdc1
intel# tune2fs -O ^needs_recovery /dev/hdc1
intel# fsck -fD /dev/hdc1
fsck 1.29 (24-Sep-2002)

HDD を Link Station に戻して Link Station を起動する。
無事起動する。ホッ

あれ？needs_recovery が付いている。
実験機上では付いていないことを確認したのに。謎。
とりあえず、様子を見ることにする
