Монтирование дисков в rescue режиме

Этот мануал для монтирования дисков, если они в RAID 1 или в RAID 0 и прочих RAID'ах.
Так как когда RAID на сервере, то надо монтировать разделы диска, а не отдельные диски.

Вводим: fdisk -l получаем список дисков и их разделов, если SATA/SSD диск:

Для SATA диска название: Disk /dev/md1: 277.5 GiB, 297917153280 bytes, 581869440 sectors
Для NVME диска название в самом конце: Disk /dev/md2: 418.2 GiB, 449020100608 bytes, 876992384 sectors

Для примера по первому серверу, для второго будет аналогично просто другое название раздела.

Раздел у нас /dev/md1 значит будем его монтировать.

Монтировать раздел можно в любую папку. Я для примера создал папку: mkdir /home/disk1.

Монтируем раздел в папку:

mount /dev/md1 /home/disk1

После работ с разделом, надо его размонтировать, для этого есть команда:

umount /home/disk1

FAQ:

— Если вам надо перекачать файлы по SFTP, то все файлы ОС находятся в папке /home/disk1.
— Чтобы зайти по root через консоль на монтированный раздел пишем команду:
chroot /home/disk1
