--VV4b6MQE+OnNyhkM Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I'm CCing zfs-discuss@opensolaris.org, as this doesn't look like FreeBSD-specific problem. It looks there is a problem with block allocation(?) when we are near quota limit. tank/foo dataset has quota set to 10m: Without quota: FreeBSD: # dd if=3D/dev/zero of=3D/tank/test bs=3D512 count=3D20480 time: 0.7s Solaris: # dd if=3D/dev/zero of=3D/tank/test bs=3D512 count=3D20480 time: 4.5s With quota: FreeBSD: # dd if=3D/dev/zero of=3D/tank/foo/test bs=3D512 count=3D20480 dd: /tank/foo/test: Disc quota exceeded time: 306.5s Solaris: # dd if=3D/dev/zero of=3D/tank/foo/test bs=3D512 count=3D20480 write: Disc quota exceeded time: 602.7s CPU is almost entirely idle, but disk activity seems to be high. Any ideas? --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
