Managing Storage Nodes entails monitoring the amount of usable space on each node, using watermark settings, and applying Storage Node configuration settings.
More information
Monitoring Storage Node capacity
To monitor the amount of usable space available on a Storage Node go to Storage Node > LDR > Storage > Overview > Main and note the current value for the attribute Total Usable Space (STAS).
What watermarks are
You use watermark settings to globally manage a Storage Node’s usable storage space. Watermarks settings trigger alarms that assist you in monitoring available storage and determine when adding Storage Nodes is required.
Storage Node configuration settings
Depending on your requirements, there are several configuration settings for Storage Nodes that you can apply.
Managing full Storage Nodes
As Storage Nodes reach capacity, you must be expand the StorageGRID Webscale system through the addition of new storage. There are two options available when considering how to increase storage capacity: adding Storage Nodes and adding storage volumes.
