Answer

It is used to prevent the creation of new FlexVol volumes when the maximum number of trees allowed or configured in an existing volume has been reached.
 

WARNING

This option does not enable reuse of existing volumes that have already reached their qtree limit. If all existing volumes are full, Trident will fail to provision new volumes rather than creating new ones.

 

Additional Information

  • In the example below, Trident will not create new PVCs and volumes in the backend when it reaches 50 qtrees
  qtreesPerFlexvol: "50"
  limitVolumeSize: "500GB"
  denyNewVolumePools: "true"
