Rescue Mode

Rescue mode boots your instance into a minimal Linux rescue system, allowing you to troubleshoot boot issues, repair filesystems, reset passwords, or recover data.

How It Works

1. A rescue ISO is temporarily attached to your instance
2. The boot order is changed to boot from the rescue system
3. Your instance reboots into the rescue environment
4. Your original disks are available for mounting and repair

Enabling Rescue Mode

1. Go to your instance detail page
2. Click Enable Rescue in the power controls
3. Confirm the action (this will reboot your instance)
4. Connect via Console (VNC or serial terminal)

Working in Rescue Mode

Once booted into rescue mode, your original disk is NOT mounted automatically. Mount it manually:

# List available disks
lsblk

# Mount your root partition
mount /dev/sda1 /mnt

# Chroot into your system (optional)
chroot /mnt

Common Tasks

Reset root password:

mount /dev/sda1 /mnt
chroot /mnt
passwd root
exit

Fix fstab:

mount /dev/sda1 /mnt
nano /mnt/etc/fstab

Check filesystem:

fsck /dev/sda1

Disabling Rescue Mode

1. Go to your instance detail page
2. Click Disable Rescue in the power controls
3. Your instance will reboot back to its normal OS
