The Rescue System
The Rescue System is a Linux live environment that allows you to have administrative access to your server. The environment starts from the network (PXE boot) and runs in the memory of the server. This makes it possible to carry out repairs to the installed system, to check file systems or to install a new operating system.
Starting the Rescue System
Activating the Rescue System
To start a server in the Rescue System, it needs to be activated in the client area.
Under "Main Functions; Server" select the desired server and then click "Rescue". Here the desired variant can be activated.
The password that was given to you when you activated the FreeBSD Rescue System can now be used to login as "root" via SSH.
Restarting the Server
To load the Rescue System, the server must be restarted.
If you no longer have access to the server, you can use the reset function in the client area. You will find the "Reboot" of the desired server.
Please note that the activation of the Rescue System automatically becomes inactive after one hour. If the server is restarted later, the system will boot from the internal drive(s).
Mounting the Drive(s) in the Rescue System
Without Software Raid
You can display the detected drives.
ls /dev/[hsv]d[a-z]*[0-9]*
# e.g. /dev/sda /dev/sda1 /dev/sda2 /dev/sda3
You can then mount the desired drive/partition.
mount /dev/sda3 /mnt
With Software Raid
You can display the detected MD devices.
ls /dev/md*
# e.g. /dev/md0 /dev/md1 /dev/md2
You can then mount the desired MD device.
mount /dev/md2 /mnt
Mounting LVM Volumes
You can display the LVM Volumes.
ls /dev/mapper/*
# e.g. /dev/mapper/vg0-home /dev/mapper/vg0-root /dev/mapper/vg0-swap
You can then mount the desired LVM volumes.
mount /dev/mapper/vg0-root /mnt
Resetting the Root Password
To reset the root password of the server, you must first mount the drives, you will find above.
Then use chroot to switch into the mounted system.
chroot-prepare /mnt
chroot /mnt
You can now change the password directly by using passwd.
passwd
