You might need to expand a PersistentVolume (PV), for example, if you need more disk space for Sisense or the Sisense
application database.

To expand a PersistentVolume (PV), you can modify the config.yaml file that you used when deploying Sisense on Linux
and update the system.

**To extend persistent volumes:**

1. Log in to the Sisense CLI with the SSH protocol and the user account that was used to install Sisense.
2. Navigate to the Sisense installation folder where the install script is located.
3. Edit the config.yaml.
     

   Update the sisense\_disk\_size parameter as required by your Sisense environment or the Sisense application
   database.

   **Note:**

   Sisense\_disk\_size is the storage PVC.

   Set the update parameter as follows: update: true
4. Run the configuration script, see [Installing Sisense on Linux](https://docs.sisense.com/main/SisenseLinux/installing-sisense-on-linux.md).
