rats. > Nathan. :) OK :-) I've been wondering if I should mention this here, but I went ahead and blogged about it anyway. http://blogs.sun.com/roller/page/relling?entry=i_m_tired_of_owning Anyone who is really clever will easily get past a quota, especially at a university -- triple that probability for an engineering college. What it really boils down to is 2 things: 1. denial of service -- how to protect others from disk-hogs 2. contractual obligations -- how to charge the government (in the US anyway) for space used for government sponsored research... and pass the audit. A few years ago there was a 3rd thing: 3. how to pay for the disk space. Today, disk space is cheap. Really. All of the current college students I know carry around USB flash drives with all of their stuff on it. And iPods. If I were a college student, why would I risk my stuff being stored on the campus servers where "the man" might want to go snooping? Or, if you don't really care, use flickr, myspace, godaddy, gmail, or some other such storage service. Storage space really is becoming inexpensive. I'm not sure anybody can fix #2, but #1 can be accomplished within reason without resorting to user quotas. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
