I've just tried a yum update on one of my C7 boxes and got the following output.
I'm guessing to fix this I need to re-install the RPM, but I can't remove it because of dependancies, so how can I fix the problem? I've managed to download a later version of the RPM, but haven't managed to find the same version as the one installed.

[root@zeppo ~]# yum install There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
/usr/lib64/python2.7/lib-dynload/itertoolsmodule.so: cannot read file data: Input/output error
Please install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the current version of Python, which is: 2.7.5 (default, Sep 15 2016, 22:37:39) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]
If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
