[CentOS] bizarre problem with performance

On my messages, I only get that annoying nfs warning message that is common.

What is strange is it is the LOCAL ROOT filesystem

The NFS mounted filesystems work fine.

I was surprised that everything seems to work well on root as long as it 
is not looking at the root filesystem  filesystem type commands like df 
-h or ls

Dell did a hardware diagnostic and said there is nothing in the 
hardware. Suggesting that I boot the server into single user mode and do 
a fsck on the root filesystem
