Perhaps you need more storage capacity than the one provided by your plan.

You can increase the storage limit via:

openode increase-storage [Amount GB]

and if you need to decrease the storage:

openode decrease-storage [Amount GB]

Amount GB should be an integer, for example:

openode increase-storage 2

will add 2 GB of storage. A server restart is not required. The storage limit is increased as soon as the command is run.
