Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to
try again to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):
It seems user intervention is required (not sure why).
I tried to detach the volume and attach it to another instance but then the other instance also refused to boot with similar issue. So I guess the issue is related to that volume.
May I ask what's really going on and how I got into this situation?
How should I proceed?
Is this related to Ubuntu only? Just started an Amazon Linux and attached volume to it, here at least I can mount it.
