yum quit working SOLVED!

Thank you, I tried the above command and that gave me my first clue as
to the problem.

I have my cache stored on an nfs mount, the exported directory has rw
permissions on user and group with group set gid and the group owner is
users.  All of my standard login accounts are members of group users
which allows individual to share any folder stored on that export.

For whatever reason the export and underlying drive got confused, as in
even logging on as root to the local machine it would not allow any
writing to that directory.

I stopped the nfs and smb services, unmounted the mount, forced an fsck
check, then remounted the mount point and restarted the nfs and smb
services.  All works fine now.

Later I will dig into the logs and see if there is any thing interesting
in them, if so I will post back what I find.

Thanks to all for you suggestions and assistance.
