Not enough space on device and unable to SSH.

Question

Hi all,  
So I am an noob to AWS but I have been running a bitnami-wordpress site on an Ubuntu EC2 t3.small for about 2 years. I recently came across an issue where I can not longer access my site (Service unavailable 503) and I am also unable to SSH in to my instance (timed out). After looking at the system log I found several errors with "OSError: No space left on device". So I did the following steps  
  
Stop the instance.  
Created a snap of the volume.  
Created a new volume from snap with larger size.  
Detached the old volume and attached the new one.  
Start the instance.  
  
Looking at the system log after starting the instance, I am still getting the not enough space error and an error with "Failed to start Apply the settings specified in cloud-config". Since I cant SSH in to the instance, I am unable to extend the os to the new volume. Can someone please help with his issue. Thank you.  
  
Sincerely,  
Steve

Thank you very much that solved my issue!

Answer

maybe you can spin up a temp new running instance.  
  
Connect/mount the "full" volume to the new running instance   
  
cd into it and delete some stuff to free up space and  
then you should be able to run it and expand the file system.  
  
As a root user the system should reserve a small amount of  
space for the root user and should be able to mount and free up  
some space.  
  
Thinking about it, once you have the full volume mounted to  
the temp running instance you should be able to expand the file  
system from there.
