I tried to create some swap files in /dev directory for my desktop. the dd and mkswap were ok. but when I try to swapon it, i get this:
# swapon /dev/myswap swapon: /dev/myswap: Invalid argument
but when I mv the file to some other directory like /mnt or /, the swapon works.
could sb. tell me why?
/dev is not a real directory for data files. You should actually make a separate partition for swap Otherwise, you can put it in some real file spaca such as in /usr or where you left a lot of space. That is often done to increase available swap space when the originally created swap partition is not large enough - add some from file space.
