Vaai Unmap

Posted: March 30, 2012 in SAN, virtualisation, VMWARE

Chad muses on being more open here on providing information to partners and customers and then inadvertently proves it by succinctly identifying that Unmap for VAAI returns in update 1 but is no longer automatic, but instead a vmkfstools command.
Probably the only way to easily reclaim space on thin provisioned volumes right now without the long delays or timeouts.
No doubt VMware’s engineering effort will continue and we’ll see it added back as an automatic process in a later update.
