How do I use my server’s rescue system?

You can find the rescue button in your myhosttech customer center when you click on server center at the top. Then you can switch to the server settings to trigger the rescue boot.

The rescue system is a minimal Linux system with the most important tools for repairing a faulty server system, which runs in the memory of your server after it has been restarted.

You will automatically receive a new temporary password for your server after booting.

Boot the server in the rescue system and use the new root password to establish an SSH connection to the server to check it and fix the problems.
After that you can perform another “reset” so that the server starts in normal mode.

A temporary operating system is loaded in rescue mode so that the hard disks in the server are not automatically integrated (mounted). You therefore have no access to the file system of your hard drives until you have mounted them manually.
The following commands are required to mount the hard drives:

Output of the existing hard drives and their partitions:

fdisk -l

Mount a partition:

mount /dev/sdXY /mnt
X = Plattenbezeichnung (a, b, ...)
Y = Partitionsnummer (1, 2, ...)

Putting together a raid from existing raid partitions and then mounting it:

mdadm --assemble /dev/md0 /dev/sdXY /dev/sdXY
mount /dev/md0 /mnt
X = Plattenbezeichnung (a, b, ...)
Y = Partitionsnummer (1, 2, ...)

After mounting, the data is available in the /mnt directory.

Remove mounting:

umount /mnt

Then you can do a “reset” again so that the server starts in normal mode.
