Sounds like you have enough users to have a pretty good idea of the average bytes per file. Use -i to specify that when you newfs. Don't overdo it! It's pretty frustrating to have 400G left on the drive an no inodes left to create any new files, but if you've got 50% of the space full and only 20% of the inodes, you can definately adjust this some. There's also -g and -h options. I'm not sure what effect these have, however. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
