Nope, there's no easy way to repartition a drive. While FreeBSD is willing to let you change the size of partitions without requiring a reboot, that just physically changes the partition, it doesn't effect the file system. There are tools in development that will let you increase the size of a partition with a file system on it then grow the file system to use all the parition, but that's about it. If you really can't dump and restore the file system that you want to shrink to do this, you can use vn to use a file in the file system as swap space. Detailed, step-by-step instructions are in the FAQ entry on adding swap at <URL: http://www.freebsd.org/FAQ/admin.html#ADD-SWAP-SPACE >. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
