A couple of my NetApp NFS volumes are being overly deduplicated, usually that’s a good thing but DFM (Data Fabric Manager) is set up out of the box to notify you if they reach the 140% and 150% marks. This is an easy fix.
To eliminate these alerts set the over deduplication thresholds to a higher value in the DFM server:
dfm options set volNearlyOverDeduplicatedThreshold=<higher value>
dfm options set volOverDeduplicatedThreshold=<higher value>
