Use dd to create a file of the correct size: dd if=/dev/zero of=SWAPFILE bs=1m count=n (where n is how many mb of swap you want to add) 2. Use vnconfig to assign this file to a vnode: vnconfig -e /dev/vn0b SWAPFILE swap To make it permanent, edit /etc/sysconfig and find the swapfile= entry and put your file there. >Is there a command that will report the amount of swap space left ? pstat -T is one >(i.e. the amount of swap not in use ?) >surely df should handle this ? Nope. swap is not a mounted filesystem. -- Nick Sayer <nsayer@quack.kfu.com> | N6QQQ @ N0ARY.#NORCAL.CA.USA.NOAM | "[Ted Kennedy] immatures with age." +1 408 249 9630, log in as 'guest' | URL: http://www.kfu.com/~nsayer/ | -- Mort Zuckerman
