Currently you cannot extend the volume your SQL instance is on in RDS. (you can on MySQL and other platforms)
Not even creating a new Instance from the Snapshot.
You basically have to back up your databases to S3, create a new Instance with matching specs and larger volume. (renaming the servers)
And restore the database from the S3 bucket.
You have to recreate the logins.
I've tried numerous ways to extract the logins from the original server that contains the password.
So far, no luck. I'm guessing it is because of the limitation of privileges you get in RDS. (non-sysadmin)
I noticed there is an 'rds_help_revlogin' (and rds_hexadecimal) in the master database but I don't have permissions to execute it, even though I'm using the account used when creating the Instance.
I get nothing at all when I google rds_help_revlogin. Is that something that is coming from AWS in the future?
Anyone have any luck scripting the login from RDS SQL Server that contains the password?
