If so, do you have quotas enabled on the host? See the handbook if you haven't already: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/quotas.html > I'm doing this on a 9.0-RELEASE system Another way to set hard quotas for jails is to give each one its own filesystem of fixed size. This is trivially easy with zfs--just create a zfs for each jail and set the quota property. To use UFS you can create image files of whatever size you want, make them md(4) devices, and then newfs(8) and mount(8) them. Unlike the method in the handbook, neither of these options requires kernel quota support. JNhome | help
