Changes

A project or a share was deleted.

Cause

The cause is due to Bug 15783635 nas_snapmgr unnecessarily tries to take snapshots of datasets that have been deleted.

Solution

The solution to stop the messages being logged is to restart the Appliance Kit Daemon (akd).

NOTE: Restarting akd may affect data services, please see document:

NOTE: Restarting the akd will disconnect you from the current session.

To restart akd from the CLI do the following;

CLI> maintenance system restart
