Once a file is written to WORM, it cannot be removed, so our users never see ``please clean up your files'' mes- sages and there is no df command. We regard the WORM juke- box as an unlimited resource. The only issue is how long it will take to fill. Our WORM has served a community of about 50 users for five years and has absorbed daily dumps, con- suming a total of 65% of the storage in the jukebox. In that time, the manufacturer has improved the technology, doubling the capacity of the individual disks. If we were to upgrade to the new media, we would have more free space than in the original empty jukebox. Technology has created storage faster than we can use it. i don't use venti, i use the original file server, but this still holds true of any worm system. in the 6 years i've had my worm, i've used 12gb. yet the size of my worm went from 18gb to 1500gb. - erik
