Finger Printing Status

Summary

Nutanix Alert A1068 - Fingerprinting Disabled

Causes

The metadata disk is used for metadata and data. Once the metadata portion on the disk exceeds the safety threshold we disable fingerprinting (deduplication) of future writes. Metadata sizes can increase due to a variety of reasons such as having too many snapshots, or simply because too much data is fingerprinted.

Resolutions

Once the metadata size is brought under the safety limit (for example, by removing unneeded snapshots, or by expanding the cluster size), contact Nutanix support to manually enable fingerprinting.
