Sounds like your boot/root is not what you think it is. I had an LFS
system I built long ago and added CentOS to it. It could be booted from
either HD. I forgot to change my root= stuff in fstab when I finally
converted fully. Took me awhile to figure out why changes I made had no
effect on booting. I changed my root in fstab and all worked well after
that.
