[CentOS] Yum errors

Hi,

I have a machine that recently had some file system corruption. fsck was able repair the file system but I am getting the following error when I try to do yum update:

[Errno 21] Is a directory: '/var/lib/yum/yumdb/e/2f883c08e3b596b66fcc19c6b4d73b11c9aaa43e-e2fsprogs-1.41.12-14.el6_4.2-x86_64/checksum_type'

In searching Google, some suggested renaming the yumdb but that just results in a traceback when I run yum.

There are some files in lost+found but I am not sure what the above file should look like and inode numbers are not useful to me.

Anyone have an idea how to fix this without reloading the machine?

Regards,
