x If your system has its root filesystem on an MD array (RAID), it needs
x to be started early during the boot sequence. If your root filesystem is
x on a logical volume (LVM), which is on MD, all constituent arrays need a
x to be started. a
x a
x If you know exactly which arrays are needed to bring up the root a
x filesystem, and you want to postpone starting all other arrays to a a
x later point in the boot sequence, enter the arrays to start here. a
x Alternatively, enter 'all' to simply start all available arrays. a
x a
x If you do not need or want to start any arrays for the root filesystem, a
x leave the answer blank (or enter 'none'). This may be the case if you a
x are using kernel autostart or do not need any arrays to boot. a

x If your kernel supports it (>> 2.6.14), mdadm can periodically check the x
x redundancy of your MD arrays (RAIDs). This may be a resource-intensive x
x process, depending on your setup, but it could help prevent rare cases x
x of data loss. Note that this is a read-only check unless errors are x
x found; if errors are found, mdadm will try to correct them, which may x
x result in write access to the media. x
x x
x The default, if turned on, is to run the checks on the first Sunday of x
x every month at 01:06 o'clock. x
x x
x Should mdadm run monthly redundancy checks of the MD arrays? x

x Unless you have compiled multiple device (MD) support into the kernel x

LS-WSGL debian 化の残課題まとめ
１．debian がまともに動くようにする
１）起動時のエラーつぶし
(1)md0 のマウント
・ネットワークの設定
・パッケージリストのアップデート
・mdadm のインストール
２）標準ファームによる RAID 化(md0, md1, md10)
３）電源スイッチによる電源OFF実現
４）LED の点滅解除
５）パッケージのアップデート
６）swap の有効化
２．手順化、ハックキット化
１）シリアルコンソールを使わないインストール方法の検討
２）インストーラ作成
