Shortly after writing my previous blog I ended up right back where I started, with Fedora 15 dropping straight into emergancy mode. I did some poking and found out it had failed to mount my three JFS partitions. I tryed mounting them by hand and it said wrong FS type which was the error I was getting when I was working on installing Fedora 15 with JFS eariler.
When Fedora 15 drops into Emergency mode because it cannot mount JFS partitions, do the following for each partition and then hit Ctrl + D to boot normally.
fsck.jfs /dev/sda#
