"복구" 모드에서 서버의 파일을 복구하는 중입니다. RAID1에 2x3TB를 갖춘 Ubuntu 12.04입니다. 지침은 "Rescue" 모드에서 서버에 SSH로 접속하고, 파티션을 마운트하고, chroot로 /mnt파일을 복구하는 것이었습니다. chrooting 후에 루트 비밀번호도 변경해야 합니다 .
문제:/var/www대부분의 파일이 있는 파티션을 마운트할 수 없는 것 같습니다 .
내가 장착을 시도했을 /때/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
그러나 chroot내부에는 아무것도 보이지 않습니다 /var/www!!! 내가 잘못 마운트했거나 모든 데이터를 잃어버렸나요?
root@rescue:~# chroot /mnt/
root@rescue:/# ls /var/www
root@rescue:/#
