Introduction

In some cases after restarting a VM, you may be unable to SSH into the instance. With serial-console access, you are able to recover the VM.

Prerequisites

• CLI
• Serial-console

Solution

1. Serial-console in to the VM using the CLI. More info on serial-console access can be found here.

crusoe compute vms serial-console --name $VM_NAME --project-id $project_id

2. If your terminal prompt has any root user implications, such as - 

root@hostname:~#

3. In most cases, this issue arises from an entry in the /etc/fstab file that references a RAID setup that is no longer available. To resolve this, comment out the relevant entry in /etc/fstab to allow the VM to boot normally. Following is an example /etc/fstab entry that would need to be commented out -

# /dev/md0 /var/ xfs defaults 0 0

4. You could also try running journalctl -xb to find any other issue causing the VM to boot into emergency mode.

5. Run sudo reboot

sudo reboot
