Nodes
From Administration → System → Nodes, you can protect your server’s database from write access by activating read-only mode. This allows you to avoid modifications to your server configuration and blob stores when performing system maintenance.
To enable it:
Click Nodes, under System in the Administration menu
Click Enable read-only mode
Warning
Anything that would require a change to a database will fail during read-only mode.
The button becomes Disable read-only mode when enabled. A banner appears above the main toolbar, notifying you that read-only mode is activated.
Disabling read-only mode, by clicking the Disable read-only mode button returns the server to its original, writable state.
Note
Note that if you are using one of our High Availability deployment options and a node is not shut down gracefully, this node will continue to appear on the Nodes page for a few seconds.
High Availability Clustering (HA-C) (Legacy) Notes
In High Availability Clustering (Legacy) mode, the Nodes screen also provides a summary of all active nodes. The screen keeps a record of all running nodes that you manage in table form.
When you click a row, you get a detailed summary of the chosen node.
The summary lists:
Node Identity, a unique ID accessible via the System Information
Socket Address, the address corresponding to the server
When running in HA-C mode the Nodes screen displays all synchronized nodes in the table. View the table to monitor and verify server connections.
