Rescue mode / recovery

Rescue mode is used to troubleshoot a VM that cannot boot normally or is inaccessible over SSH/RDP. The exact rescue features available depend on region and platform support.

Common uses

Repair filesystem issues
Fix bootloader problems
Reset configuration that prevents boot
Recover important files before rebuilding

How to access rescue mode (general steps)

Log in to the OneProvider Client Area.
Open OneCloud and select your project.
Open the VM/instance details page.
Look for Rescue, Recovery, or Boot options (label may vary).
Enable rescue mode and follow the on-screen instructions.

You may need to reboot the VM for rescue mode to take effect.

Note

If you do not see rescue mode for your VM, it may not be available in your region/plan.

What to do in rescue mode

Typical workflow:

Connect using the method provided (often via console or temporary credentials).
Identify disks/partitions (Linux examples):
BASH
```
lsblk
fdisk -l
```

Mount the filesystem to inspect or repair:

BASH

mkdir -p /mnt/root
mount /dev/sdXn /mnt/root

Perform repairs (examples):
- Filesystem check: fsck
- Configuration fixes under /mnt/root/etc/...
Reboot back into normal mode when finished.

Caution

Filesystem and disk operations can cause data loss if used incorrectly. If you are unsure, take backups (if possible) before making changes.
