I know that in Fedora, resolv.conf is now some symlink to a NetworkManager
file (I forget where).
Try doing ls -l /etc/resolv.conf, and see if that's the case in CentOS-7 as
well. (I don't use NM, so I'm not sure what the case is with it, as the
machine I'm using had that change made, if it was needed, long ago. :) )
If it does turn out to be a symlink, copy its information, if you need it,
then delete the file, then recreate it.
Hope this helps, but I'm not sure. It is a working solution in Fedora.
