As has already been said, you don't really need to change your swap size unless you're going to be using all of your physical memory and need the additional space. Since it doesn't sound like you're going to be putting any more load on the server, it's unnecessary. However, if you want to do it, you could, without going to single-user mode: 1) create an empty file somewhere. This will make a 1 MB file, adjust bs and count as you need to. # dd if=/dev/zero of=/path/to/some.file bs=1k count=1024 2) create a file based device with mdconfig like this. # mdconfig -a -t vnode -f /path/to/some.file 3) swapon your shiny new md device. Use the md device that was given as output from the above command. # swapon /dev/md0 4) verify that your device is now working as a swap device with # swapinfo -h 5) now you can swapoff your main swap, change it as you need, and swapon it back # swapoff /dev/ad0s1b # swapon /dev/ad0s1b 6) now that you new, improved swap is working, you can swapoff your temporary swap, remove the md device, delete the file, and verify that your swap is right # swapoff /dev/md0 # mdconfig -d -u md0 # rm /path/to/some.file # swapinfo -h Any other thoughts? BTW - is there any easy way to make sure how much RAM is currently installed other than looking into the hardware?

RE: changing swap size
If you have swap section 512 Mb that it is not necessary change anything . Simply add operative memory and all.

changing swap size
Hello, Following the advice about periodic freezes, I am going to add some RAM to my system. However, currently my swap size is 512MB. If I increase RAM to, say, 1GB, would I need to change the swap size to 2GB? If so, is it a safe process (I assume this can be done using FIPS)? Would I need to boot first in single-user mode? Any other thoughts? BTW - is there any easy way to make sure how much RAM is currently installed other than looking into the hardware?
