[SOLVED] I broke my swap!

http://forums.fedoraforum.org – Hi all. It's been a while since I've been here. I just installed F18 LXDE, and so far, so good until just now. I don't have much experience with lvm, but was trying. I reduced the lv for swap, which worked well, but now the swap is gone from fstab. I've tried putting it back in, but it won't mount, no matter how I designate it (UUID, /dev/fedora/swap, /dev/mapper/fedora-swap). I re-ran Code: mkswap /dev/fedora/swap , got a new UUID and tried that....nothing. running swapon fails, too. I know I could make a swapfile and mount that, but I'd rather fix it the right way. a (HowTos)
