Chapter 4. Monitoring Storage Cluster
The command above shows detailed information about the stor1 cluster. The general parameters
(highlighted in red) are explained in the table below.
Parameter Description
Cluster Overall status of the cluster:
• healthy. All chunk servers in the cluster are active.
• unknown. There is not enough information about the cluster state (e.g., because the
master MDS server was elected a while ago).
• degraded. Some of the chunk servers in the cluster are inactive.
• failure. The cluster has too many inactive chunk servers; the automatic replication is
disabled.
• SMART warning. One or more physical disks attached to cluster nodes are in pre-
failure condition. For details, see Monitoring Physical Disks on page 52
