I have been using SGI's XFS for Linux for a short time and am quite pleased with its performance and filesystem integrity. If you have a spare system available, it's easy enough to try it out. http://oss.sgi.com/projects/xfs/1.0_installer.html Also requires the 2 install CDs for RedHat-7.1. SGI's ftp site has a patch available to bring up XFS on Linux-2.4.5 kernel, also. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
