Initially I had created my default linux instance. Then later I created new volume of 2 GB and attached to my linux instance. Within the linux instance I did some modifications such as creating a folder name volume1 and attached the 2 GB volume to it. To avoid mounting everytime after a server reboot, I went to mtab and copied information regarding the 2 GB storage mounting and pasted the same in fstab to just use mount -all option to automatically attach all the volumes available. Later I detached and deleted the 2 GB volume from my linux EC2 instance. When I launch my EC2 instance it fails the status checks and the instance doesnot load up. I have confirmed that the volume is in the same availability zone as the instance, and the relevant security group has the correct inbound rules. I guess there is some issue happening relating the statement of the detached 2 GB volume present in fstab file of my main linux EC2 instance. Can you help me in regard of this ? I am not able to launch my EC2 instance.
I checked for system log for my main linux instance, I got the following in the end lines:
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.
Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.
Press Enter to continue.
If you think you have an invalid fstab entry, have you tried removing it? Here is some info about how to do so from a separate EC2 instance -> https://aws.amazon.com/premiumsupport/knowledge-center/ec2-linux-emergency-mode/
