我正在“救援”模式下恢復伺服器的檔案。它是 Ubuntu 12.04，RAID1 中有 2x3TB。說明是在「救援」模式下透過 SSH 連線到伺服器，掛載分割區，chroot/mnt並恢復我的檔案。我還必須在chrooting 之後更改 root 密碼。
問題：/var/www我似乎無法安裝大部分文件所在的分割區。
當我嘗試安裝/並/var/www
root@rescue:~# mount /dev/md3 /mnt/
mount: /dev/md3 already mounted or /mnt/ busy
mount: according to mtab, /dev/md3 is already mounted on /mnt
root@rescue:~# /dev/sda /mnt/var/www
mount: /dev/sda already mounted or /mnt/var/www busy
然而當chroot我看到裡面什麼都沒有之後/var/www！我是否安裝錯誤或遺失了所有資料？
root@rescue:~# chroot /mnt/
root@rescue:/# ls /var/www
root@rescue:/#
