# Local Filesystem

The **Local Filesystem** storage node is the default storage node after installing CTERA Portal.

**Note**

You cannot use a **Local Filesystem** storage node for storage that exceeds 20TB.

When using a **Local Filesystem** storage node, data blocks are stored in a specific folder in the primary CTERA Portal server's local file system.

CTERA Portal servers set to secondary mode access the storage node by communicating through the primary CTERA Portal server. ![Image](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-M2LYEWAE.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A11%3A31Z&se=2026-11-11T05%3A11%3A31Z&sr=c&sp=r&sig=iLzOywoHk%2BUePBOAP01QZci0WzUsVgcK%2FVAa9aqQuoE%3D) **Host Address** – The IP address of the primary database server. **Folder Path** – The path where files are stored in the local file system. **Folder Size** – The maximum number of files to store in a folder. The default value is 1024. **Use fsync** – Blocks of data should be flushed to disk immediately. Using fsync prevents data loss in the event of a power failure.
