VMware vSphere ESXi

Issue/Introduction

Symptoms:
Automatic UNMAP may not work after deleting files from VMFS6 and running manual UNMAP command.

Environment

VMware vSphere ESXi 6.5

Cause

Manual UNMAP still progressing, even after 24 hours. This causes the conflict with the Automatic UNMAP.

Resolution

There is no fix, at the moment, but VMware engineering is investigating.

Workaround:
The recommendation is not to use manual UNMAP when you have VMFS6 because automatic UNMAP is already enabled and working.

There is an option in vSphere 6.7 to increase the resources allowed for automatic UNMAP.
