For a production machine where you have to schedule down time I would suggest going 1/2 way. Thankfully now, the vn(4) device is available as a kld, so you don't have to re-compile the kernel. Create a file on one of your faster drives, configure it as swap space with vnconfig(8), and then use it with swapon(8). And, the best part is, there's already a how-to on this at the FreeBSD Diary: http://www.freebsddiary.org/swap.php But, again, for a production machine, I would _STRONGLY_ recommend that at the first opportunity you have to take it down and arrange for more raw swap space. --Chris > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Chris Fedde > Sent: Saturday, January 26, 2002 11:42 AM > To: alexus > Cc: freebsd-questions@FreeBSD.ORG > Subject: out of swap space > > > On Sat, 26 Jan 2002 09:01:08 -0500 "alexus" wrote: > +------------------ > | hi > | > | is there a way to increase size of swap space? > | > | i have 512mb of ram and 512mb of swap space > | > | i had 256mb of ram before so i created 512mb of swap space > | now i put another 256mb in and i'm still running out of space > | > | so i was asking if there is a way to increase size of swap space? > +------------------ > > You want to spread your swap over all the drives in the box.
