Currently, I am running a data retriever on the cloud and save the data in the database on a docker container. Until today, I was able to ssh into the instance (and therefore the docker container), but now I am not able to do so anymore. When I do the ssh, I get the following error:
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
Doing the suggested troubleshoot, it seems that there is no problem with any of the issues tested.
I have looked at other stackoverflow questions, such as stackoverflow. My assumption is that indeed the disk is full, so I tried to increase the disk size. However, since I am not able to ssh into the instance (also not after increasing the persistent disk size, using gcloud compute disks resize), I am unable to format the disk as suggested in format disk on Google Cloud. Further, I tried removing the ssh keys and adding them again, but to no avail. Right now, I'm a bit lost.
Do you know a solution to ssh into the VM instance again?
Looking forwards to your replies.
