While it may be not suitable in your specific case, as I stated before, in many cases where user quotas are not needed, x4500+zfs is a very compelling solution, and definitely cheaper and more flexible (except user quotas) than NetApp. While I don't need user quotas I can understand people who do - if you have only a couple (hundreds?) file systems and you are not creating/destroying them then approach file system per user could work (assuming you don't need users writing to common file systems and still have a user quota) - nevertheless it's just an workaround in some cases and in other it won't work. -- Best regards, Robert Milkowski mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
