I'm getting the following error on a nightly basis from my EqualLogic PS4100:

"WARNING event from storage array PS4100

subsystem: MgmtExec

    event: 8.3.65

     time: Mon Jun  6 00:00:00 2016

Free space is below threshold of 15 percent for pool default. Default Snapshot Schedule will run with max-keep set to 1."

I don't have any volumes with space reserved for snapshots, and I don't have any snapshots scheduled.   Any ideas on what I can do to get rid of the warning
