After a migration from 7-mode 8.1 to cdot 8.3 we have a volume that has some depup issue. We opened a NetApp case and they recommended us to execute "volume efficiency undo" but they told me that it will also cause short cifs interruptions (which is not really great on a production volume...).
On the command man page, there's no info about any disconnection risks, so do someone have any feedback regarding the risk of this command? Or is it safe to run it on the volume outside a maintenance windows?
Many thanks for your feedback.

As per Netapp documentation"https://library.netapp.com/ecmdocs/ECMLP2348025/html/volume/efficiency/undo.html" there should be no impact on the production while executing the "Efficiency Undo" command however a warning to be kept in mind "Adding more data while the 'efficiency undo' operation is in progress will cause the undo to fail if there is insufficient free space to complete the operation" hence prefered to do it during maintenance windows.
