I run dd if=/dev/zero of=testfile bs=1024k count=5 inside the iscsi vmfs
from ESXi and rm textfile.
However, the zpool list doesn't decrease at all. In fact, the used storage
increase when I do dd.
FreeNas 8.0.4 and ESXi 5.0
Help.
Thanks.

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?
Kind regards

Did you also
I forgot about compression. Makes sense. As long as the zeroes find their way
to the backend storage this should work. Thanks!
