Why should it?

Unless you do a shrink on the vmdk and use a zfs variant with scsi
unmap support (I believe currently only Nexenta but correct me if I am
wrong) the blocks will not be freed, will they?

Solaris 11.1 has ZFS with SCSI UNMAP support.

Seem to have skipped that one... Are there any related tools e.g. to release all "zero" blocks or the like? Of course it's up to the admin then to know what all this is about or to wreck the data
