I have RTFM'd through this list and a number of Sun docs at docs.sun
and can't find any information on how I might be able to write out 'hard
zeros' to the unused blocks on a ZFS. The reason I'd like to do this is
because if the storage (LUN/s) I'm providing to the ZFS is
thin-provisioned and doesn't know about a host O.S. file system and
whether a previously written disk block still has data on it, only
knowing it doesn't if all zero's are written, then how would I go about
doing that with ZFS? I was looking at the command mkfile, which looked
like it might do it, but I wasn't sure. Has anyone done this before and
can provide the instructions?
