My computer is up and running again. These instructions did the trick. mount -n -o remount,rw / This will remount root as read-write and you should be able to edit the fstab. After you finish, do a control-d to reboot. I then had a problem with the NVIDIA display. I found that /usr/lib64/xorg/modules/libwfb.so had become a link to libnvidia-wfb.so.1. Looking at my identical setup on another computer, I copied the libwfb.so from the second computer to the one with the video problem. With a reboot, the display is working again. Thanks for all the help including reviewing the commands for logical volumes, UUIDs and the remount.
