RAID 1 (2面ミラー)作成
準備
VMにプライマリと同じサイズのディスクを追加する。今回は12Gbyte HDDを追加。
関連ファイルのバックアップを行う。それぞれ、cp -p 元ファイル名 元ファイル名.yyyymmddなどでバックアップ。
- /etc/vfstab
- /etc/lvm/md.tab
- /etc/lvm/mddb.cf
- /etc/system
- /boot/grub/menu.lst
ディスクの命名規則は以下の通りとする。
| mount | ミラーディスク名 | サブミラー名 | |
|---|---|---|---|
| c0d0上 | c0d1上 | ||
| / | d0 | d10 | d20 |
| /var | d3 | d13 | d23 |
| swap | d4 | d14 | d24 |
| /opt | d5 | d15 | d25 |
| /usr | d6 | d16 | d26 |
| /export/home | d7 | d17 | d27 |

追加した構成で起動できる事を確認する。
RAID 1 (3面ミラー)作成
2面ミラー構成後に3面ミラーにする手順は下記の通り。
準備
VMにプライマリと同じサイズのディスクを追加する。今回は12Gbyte HDDを追加。
関連ファイルのバックアップを行う。それぞれ、cp -p 元ファイル名 元ファイル名.yyyymmddなどでバックアップ。
- /etc/vfstab
- /etc/lvm/md.tab
- /etc/lvm/mddb.cf
- /etc/system
