You will not see the on disk size of the file with du before the transaction group have been committed which can take up to 30 seconds. ZFS does not even know how much space it will consume before writing out the data to disks since compression might be enabled. You can test this by executing sync(1M) on your file server, when it returns you should have the final size of the file. Regards Henrik http://sparcv9.blogspot.com
