もうパーティションの開始アドレスとかを気にしなくても良くなるLVMを試してみた。

LVMは物理ボリュームをグローバルボリュームとしてまとめ、論理ボリュームとして切り出して使うイメージだ。
これの使い道はkvmのディスク等いろいろ使えそう

PV(=物理ボリューム) ⊆ GV(=グローバルボリューム) ⊇ LV（論理ボリューム）

(1)物理ボリュームを作成
※lvmに使うパーティションはpartedでset n lvm onをしておく。

# pvcreate /dev/sda1

(2)ボリュームグループを作成

# vgcreate VG_SDA /dev/sda1

(3)論理ボリュームを作成

# lvcreate -L 40G -n home.cur VG_SDA

確認例

# vgdisplay -v

Expectを使えるか試してみようと「sed」と対話するスクリプトを作った結果・・・
●スクリプト

#!/bin/expect -f
 
spawn sed -e "s/Q/A/g"
set timeout 1
 
send -raw "Q\n"
expect {
        -re "A" {puts "OK!"}
}

send -raw "Q\n"
expect {
        -re "Q" {puts "No Change!"}
}
 
send -raw "Q\n"
expect {
        -re "B" {puts "Wrong!"}
}
 
close
 
exit

●結果

spawn sed -e s/Q/A/g
Q

OK!
Q
No Change!

(1)/bootをext4にすると、GRUBインストール時にファイルが見つからない言うて起こられる。
※手動インストールしようとしても、ファイル名が見えなかったりする。
　私は誤ってext4にしてしまったため、ファイルを退避、フォーマット、ファイル復元と面倒で悲しい結果に・・・。

(2)HDはvirtioではなくideつなぎにする。
ideじゃないと認識せずにNo bootable diskとか・・
※インストール時にはいけたみたいですが・・・

(3)後にWindowsを入れたければ、最初のプライマリパーティション分の領域を1G取っておく。
※4Gバイト以降にVistaを入れようとしても、システムないよって起こられて
　ntfs-g3でntfs作っても起こられて、結局Windowsインストーラで５番目のパーティションを削除・新規・フォーマットして入れようとしたら・・・、１個目のパーティションにシステムボリューム作ってもいい？ってきかれました・・。そんなんどこにものってないわ。

前にssh経由でLFSを構築したことがあってほおってたマシンを再利用できないかと考えて、
また作成することにした。
今回はVNC経由でソースからの構築ではなくディストリビューションDebianを入れることにする。
