Can't add host - Failed to read hardware information - Users

7 Oct 2016

      I'm trying to add a host to a freshly built cluster.

yum install finishes, then the message " Failed to read hardware
information" is displayed - host has installation failed.
If I try to re-install I get the same message and the host goes
non-responsive.
