Seems to me that your kernel build configuration does not include the FS module, for example, if your root FS is ext4 or xfs you should select it as compiled into kernel not as a module, that should ease a lot of pain. Also the problem with compiling a new kernel is that the vanilla configuration may not work for you and configuring kernel options can be pretty daunting at first and even with each new version new stuff keeps piling in. If you are going the kernel route I suggest to check if you can get the centos kernel config, check if the centos kernel has config build-in, if it does you should have a file in /proc/config.gz which should help you bootstrap the new kernel with the correct options.
