There are 2 cases in which your database will be in read-only mode:
- You’ve intentionally set it up to prevent your dataset from being altered.
- It was automatically set to read-only mode because it exceeded it storage limits.
Although it’s not a frequent use-case, you may want to eliminate any potential for online data content changes.
Follow these steps to set your database to read-only mode:
- Navigate to the Configure tab on our admin interface and click on Edit configuration button
- On the Read-only mode section, click on Enable link
- Click on Apply and then restart button.
When a database exceeds its plan limits for disk storage the database will automatically switch to read-only mode.
We set the database to read-only in this scenario to ensure your database doesn’t exceed the assigned disk space, and to prevent further issues that can result from running out of space. We send a notification out to the account owner when disk usage reaches 70%.
If you need to check the status of your database storage limit, you can do so from the GrapheneDB UI Overview tab. From our UI, you will see the limit you have exceeded by, as well as a box alerting you of the database read-only mode.
In the GrapheneDB UI Overview tab you will find the limits of your plan and how many resources are being used by your instance. You will find all the plan limits in our pricing web page.
If you wish to switch your 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 change plan feature.
If upgrading is not an option for you, you can always empty your database from our admin interface by clicking on the Empty database button found in the Admin tab.
If you want to reduce the size of your database to stay within your plan’s limits, but don’t want to delete your complete dataset, we recommend you follow the steps below:
- 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 (Admin tab, Restore database button). You can find more information about restoring a local dataset into GrapheneDB here.
