cluster info

Returns the minimum and maximum values for key cluster attributes.

Following are the attributes for which the command returns minimum and maximum values:

  • VolumeSize — The size of the volume.
  • VolumeQuotaSize — The hard quota (disk space) for the volume.
  • VolumeAdvisoryQuota — The advisory quota (disk space) for the volume.
  • VolumeLogicalUsedSize — The logical size used by the volume.
  • VolumeNumContainers — The number of replicas for the volume.
  • VolumeGuranteedNumContainers — The number of guaranteed replicas for the volume.
  • VolumeNumNamespaceContainers — The number of replicas for the name container associated with the volume.
  • VolumeGuranteedNumNamespaceContainers — The number of guaranteed replicas for the name container associated with the volume.
  • VolumeNumSnapshots — The number of snapshots of the volume.
  • VolumeCoalesceInterval — The coalesce interval setting for the volume.
  • VolumeMaxInodesAlarmThreshold — The threshold for triggering the VOLUME_ALARM_INODES_EXCEEDED alarm.
  • VolumeMaxNsSizeMbAlarmThreshold — The threshold for triggering the VOLUME_ALARM_INODES_EXCEEDED alarm.
  • VolumeReReplicationTimeOut — The timeout value for re-replication.
  • StoragePoolCapacitySize — The total amount of disk space on the storage pool.
  • StoragePoolUsedSize — The amount of used space on the storage pool.
  • StoragePoolAvailableSize — The amount of available space on the storage pool.
