lustre_config: Operating on the following nodes: sfs1,sfs2,sfs3,sfs4
lustre_config: Checking the cluster network connectivity and hostnames...
lc_net: Verifying network connectivity between "sfs1" and "sfs2"...
lc_net: ERROR: remote_check(): Local host resolves sfs2 to IP address "192.168.8.2", while its own resolution is "192.168.8.2
192.168.8.2". They are not the same!

the address is just mentioned once in /etc/hosts

suggested Fix:
