# Enabling and Disabling Writes to a Storage Node

When you create a storage node, the node is by default in read/write mode.

You can enable or disable writes to a storage node whenever needed, such as when you are about to replace a storage node and you want to stop new data blocks from being written to the node. While writes are disabled on a node, any new data blocks to be written are directed to other storage nodes that are write-enabled. Also, the node goes into read-delete mode, in which access to data is read only or delete.

**To enable or disable writes to a storage node:**

1. In the global administration view, select **Main > Storage Nodes** in the navigation pane.  

The **Storage Nodes** page is displayed.

2. Click the storage node name.  

The storage node window is displayed with the storage node name as the window title.

**Note**

For storage which has a limited amount of storage, like the **Local Filesystem** storage node, the default storage node when setting up the CTERA Portal, **Usage** displays the amount of storage available, followed by the amount of used storage. For Amazon S3 storage, the amount used is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-4R0JBPOL.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A23%3A37Z&se=2026-11-11T05%3A23%3A37Z&sr=c&sp=r&sig=lzw3le1Ds0RPawvgxZLULajTpc%2BuW1Flb%2B%2F2L%2BVFRM8%3D) For cloud storage and S3 storage other than Amazon S3, no usage is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-MU3IFS4R.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A23%3A37Z&se=2026-11-11T05%3A23%3A37Z&sr=c&sp=r&sig=lzw3le1Ds0RPawvgxZLULajTpc%2BuW1Flb%2B%2F2L%2BVFRM8%3D)
4. Slide **Writes** to **Enabled** to enable writing to the storage node or **Disabled** to disable writes.
