  • ONTAP 9

Answer

  • Prior to 9.5, the df output was showing quota used + free available in the volume as the total size.This behavior changed with the fix for bug 1059956 starting in ONTAP 9.5.
  • After 9.5, the behavior changes to df output showing only the disk limit of a quota rule on a qtree if the disk limit was larger than the volume size.This behavior changed with the fix for bug 1228408 starting in ONTAP 9.9.1.
  • After 9.9.1, the behavior changes back to the behavior of prior to 9.5, but also takes into account the max-autosize value of a volume.If a quota disk limit/volume size is 50GB, but the max-autosize is 100GB, the volume free space is calculated from max-autosize minus volume used.
