# Persistence Clusters Status Table

The persistence clusters status table presents the state of persistence clusters and services. In the top bar of the FTL GUI, click Clients then Clusters.

Information and actions are listed in the following table. You can click a cluster row to expand a Servers List, detailing the persistence services in the cluster.

## Columns

GUI Item | Description
--- | ---
Cluster Status | The health of the cluster based on the aggregated state values of its services. For service state values, see Persistence Service States.
Name | Name of the persistence cluster.
Servers | Status summary of the persistence services in the cluster.
Stores | List of persistence stores that the cluster implements.

Note: The Attention tally in the GUI top bar does not include persistence services or eFTL services unless at least one service from the cluster is present. Nonetheless, even in a temporary situation where a cluster is configured but none of its services are present, the status table indicates that the cluster and its absent services are offline.

## Commands

Icons at the right of each cluster row trigger the following commands:

- Suspend all services in the cluster, in preparation for saving the contents of its persistence services. For background information, see Saving and Loading Persistence State, and its subtopics. You need to manually restart all persistence services to bring the cluster back online. This command is used only when disk persistence is disabled.
- Perform a manual disk compaction so all members of the persistence cluster start compaction. The compaction button only works if the persistence cluster is running. Compaction runs even if there is no space to be reclaimed. If disk persistence is not enabled, an error results. If there is not enough disk space, the persistence service will not start compaction, and will log an error message. For details, see Compact Disk Persistence Files with Persistence Service Online.
- Save the data state of all the persistence services in the cluster. This command is visible only when it is available. For background information, see Saving and Loading Persistence State, and its subtopics. This command is used only when disk persistence is disabled.
- Back up the disk(s). When disk persistence is enabled, this command backs up the files associated with disk persistence. See Disk Persistence Backup and Restore.
- Force this cluster to form a quorum. This command icon is visible only when it is relevant. Before using this command, read Before Forcing a Quorum.
