BTREE GC arbejder langsomt i chunk-genvindingsfasen. Denne advarsel genereres, hvor der er mere end 1 TB fuldt affald, og forskellen mellem affaldsdetekteringshastigheden og genvindingshastigheden for affaldsklumpen er større end 100 GB. Advarslen sendes, når systemet har været i denne tilstand i 7 dage.

1. Opret forbindelse til en af noderne i klyngen via en putty-session.
2. Kontroller den aktuelle sensorstatus.

# svc_rest_cmd -i `hostname -i` /vdc/sensor/status/BtreeChunkLevelGC
svc_rest_cmd 1.0.10

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SensorStatusList>
  <SensorId>BtreeChunkLevelGC</SensorId>
  <ListSensorStatus>
    <SensorStatusRestRep>
      <ContextId>Btree Chunk Level GC</ContextId>
      <CurrentState>OK</CurrentState>
      <NodeId>1f4368c3-37cd-467f-9efc-289264806ea0</NodeId>
      <PreviousState>OK</PreviousState>
      <Time>1551118064264</Time>
    </SensorStatusRestRep>
  </ListSensorStatus>

3. Se efter <CurrentState>, hvis den er indstillet til OK, er fejlen ikke aktiv, og dette er sandsynligvis en falsk alarm. Ignorer advarslen, men hvis den udløses igen inden for den næste uge, skal du åbne en serviceanmodning hos teknisk support
