actualreplication

arf

The actual current replication factor by percentage of the volume, as a zero-based array of integers from 0 to 100. For each position in the array, the value is the percentage of the volume that is replicated index number of times. Example: arf=5,10,85 means that 5% is not replicated, 10% is replicated once, 85% is replicated twice.

advisoryquota

aqt

A value of 0 indicates there are no soft or advisory quotas for this volume

AdvisoryQuotaExceededAlarm Alarm raised if the volume size is more than the value configured for the advisory quota.

aename

aen

Accountable entity name

aetype

aet

Accountable entity type:

AlmostFullTopologyAlarm Alarm raised if the topology disk usage exceeds the value configured for the almost full percentage.
auditedeaA value of 1 indicates that auditing is enabled for the volume. See Enabling Auditing for the steps to enable auditing on a volume and on directories, files, and tables in that volume.
coalesceIntervalci

The interval of time during which only the first instance of an operation on a node is recorded in audit logs, if auditing is enabled. Subsequent identical operations performed on the same node are ignored during the interval. Setting this field to a larger number helps prevent audit logs from growing quickly.

The default value is 60 minutes.

ContainersNonLocalAlarm Volume is local but does not have any containers on the local node.

creator

on

Name of the user that created the volume

creatorcontainerid ID for the container.
creatorvolumeuuid ID that supports the container chain identification for mirroring. The creatorcontainerid  and creatorvolumeuuid fields combined form a unique identifier for the container chain.
DataUnavailableAlarm Alarm raised if the data is not available.
DataUnderReplicatedAlarm Alarm raised if the data is under replication.
dbrepllagsecalarmthresh Defines the lag time in seconds for replication after which the "Table Replication Lag High" alarm is raised.
FullTopologyAlarm Alarm raised if the topology disk usage is 100%.
InodesExceededAlarm Number of files in the volume has been exceeded. the threshold (50 million).
lastSuccessfulMirrorTime Last time when the mirror completed successfully.
limitspread An internal flag for MapR volumes to control the growth of volumes in terms of the number of containers. When this flag is set, CLDB tried to limit the numb of new containers created depending on the present size of the volume. If the volume size (the data in the volume) is small, the CLDB tries to reuse space in existing containers thus avoiding the creation of new containers.
localpath Topology of the volume

logicalUsed

dlu

Logical size of disk used by this volume

maxinodesalarmthreshold

miath

The threshold of inodes in use that will set off the VOLUME_ALARM_INODES_EXCEEDED alarm

minreplicas

mrf

Minimum number of replicas before re-replication starts.

mirrorDataSrcCluster Name of the cluster of the originator volume.
mirrorDataSrcVolume Name of the originator volume. This is used to identify the mirror family in cascaded mirroring.
mirrorDataSrcVolumeId ID of the originator volume.
MirrorFailureAlarm Alarm raised if mirroring fails.
mirrorId Current mirror ID of the volume.
mirror-percent-complete Progress bar for the current mirror.
mirrorscheduleid ID of the schedule that determines when the volume needs to be mirrored.
mirrorSrcCluster Name of the source cluster from which the current mirroring will happen.
mirrorSrcVolume Name of the source volume from which the current mirrroring will happen.
mirrorStatus Status of the last mirror attempt.
mirrorthrottle Flag to determine if the throttling need to be done on mirroring.
mirrortype 

Determines the type of volume:

  • 0 - Read-write Volume
  • 1 - Mirror Volume
  • 2 - Mirror than can be converted to read-write
  • 3 - Read-write volume that can be converted to mirror

mountdir

p

The path the volume is mounted on

mounted

mt

A value of 1 indicates the volume is mounted

nameContainerSizeMB

ncsmb

 

namespaceMinReplicansMinReplicasMinimum replication level for the namespace container.
namespaceNumReplicansNumReplicasReplication level for the namespace container.

needsGfsck

nfsck

A value of TRUE indicates this volume requires a filesystem check

nextMirrorId Mirror ID that will be assigned if the mirroring successfully completes the next time.
NoNodesInTopologyAlarm Alarm raised if there are no nodes in the topology where the volume belongs.
numcontainers Number of containers that the volume has.

numreplicas

drf

Desired number of replicas. Containers with this amount of replicas are not re-replicated.

partlyOutOfTopology

poot

A value of 1 indicates this volume is partly out of its topology

quota

qta

A value of 0 indicates there are no hard quotas for this volume

QuotaExceededAlarm Alarm raised if the volume size is more than the quota value.

rackpath

rp

The rack path for this volume

readonly

ro

A value of 1 indicates the volume is read-only

replicationtype

dcr

Replication type

reReplTimeOutSec

n/aTimeout (in seconds) before attempting re-replication of replica containers. This volume property defines the timeout period until CLDB starts re-replicating the containers on the node of the volume when CLDB stops receiving a heartbeat from the node.

scheduleid

sid

The ID of the schedule, if any, used by this volume

schedulename

sn

The name of the schedule, if any, used by this volume

snapshotcount

sc

The number of snapshots for this volume

SnapshotFailureAlarm Alarm raised if the snapshot fails.

snapshotused

ssu

Disk space used for all snapshots, in MB

TableReplicationAsyncAlarm A table being replicated under this volume has its synchronous replica fall back to asynchronous mode replication
TableReplicationErrorAlarm A table being replicated under this volume has encountered an error while trying to replicate.
TableReplicationLagHighAlarm A table being replicated under this volume has high lag time while trying to replicate.

totalused

 

Total space used for volume and snapshots, in MB

used

 

Disk space used, in MB, not including snapshots

volumeid

id

The volume ID

volumename

n

The name of the volume

volumetype

 

The volume type:

  • 0 - Read-write volume
  • 1 - Mirror volume
