When a database exceeds the maximum storage size or the node or relationship maximum counts allowed for the plan, the database will be switched to read-only mode.
If you wish to turn the database back to read-write mode, the simplest solution is to increase the database capacity by upgrading to a higher plan. This can be done by cloning the database from the UI using the Upgrade/Clone button. Please note that a new instance will be created and the original instance will also be kept running. It's your responsibility to remove the original database if you don't need it anymore to avoid any potential charges for the original database.
If you don't want to upgrade into a higher plan, but would rather like to reduce the size to be within the capacity limitations of your current plan, then you can follow these steps:
- Unpack the downloaded tarball and put the directory inside the /data directory of your local Neo4j installation.
- Start your local instance and reduce your dataset
- Stop your local instance, compress the dataset and restore your GrapheneDB database with the compressed file. Read more about the restore process here.
