Hmm, seems to work just fine here: beast:root:~# zfs create tank/foo beast:root:~# zfs set quota=3D10m tank/foo beast:root:~# dd if=3D/dev/random of=3D/tank/foo/test bs=3D1m dd: /tank/foo/test: Disc quota exceeded 11+0 records in 10+0 records out 10485760 bytes transferred in 6.109407 secs (1716330 bytes/sec) beast:root:~# df -h /tank/foo Filesystem Size Used Avail Capacity Mounted on tank/foo 10M 10M 0B 100% /tank/foo I think you just waited not long enough:) You didn't give block size argument to dd(1), so it used 512 bytes. Please be more patient, retry and report back, thanks! --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
