Actually there is great chance that you are hitting this bug :
"6792701 Removing large holey file does not free space"

Now there are no files in /dr/netapp11bkpVOL34, but
# zfs list|egrep netapp11bkpVOL34
dr/netapp11bkpVOL34 1.34T 158G 1.34T
/dr/netapp11bkpVOL34
Space has not been freed up!
The other common cause for this is if an application has an open file
descriptor open. If you have 'lsof' on the machine, can you try running it
and seeing if any progress are still accessing the file system.
or use the built-in tool:
find /proc -type f -links 0
(Will list all files which have been unlinked but which are still being
used by applications)
