How do I change from ext3 to ext2?

[Gerry Doris]

I want to do some disk rearranging and it would be really convenient if my 
partition were ext2 instead of ext3.

I thought all I had to do was use tune2fs to convert the partitions to 
ext2 and then modify fstab to indicate the partitions were ext2.  Well, 
that ended in a kernel panic with an error that the journal couldn't be 
found.

What's the right way?  Do I have to recompile the kernel? I'm using redhat 
8.
