I was trying to mount a persistant disk with my GCP instance. From the official documentation of GCP on mounting persistent disk, for enabling automatic mounting disk on VM restart I should edit the "/etc" folder to inorder to add the UUID_VALUE to the fstab.backup file. But I was unable to edit because of the permissions. So I modified the permissions for the "/etc" folder.
For example:
chmod -R 777 /etc
Now I am not able to establish ssh connection with that GCP instance now, even from Web console and gcloud cli. It's giving me the error
Connection closed by [ip_address] port 22
How can I establish ssh connection with this GCP instance. Please help me to solve this issue, Thank you.
I tried to connect to this server through ssh from webcloud, gcloud cli,vscode...but nothing is working
