Applies to

  • ONTAP 9
  • Logical Space Reporting
  • Storage efficiancy enabled

Issue

Logical space reporting enabled for the volume. This caused the client to not see the space savings from storage efficiencies which presented the volume as being almost full.
 
From the client:
root@xxxx z3]# df -h /z3/*
