CLUVFY Fails with PRVG-10467 and 'resolv.conf Integrity' about ansible-ocm12c

[dfhawthorne]

The Oracle 18.1 Error Messages Manual says:

PRVG-10467: The default Oracle Inventory group could not be determined.

Cause: An attempted Cluster Verification Utility (CVU) validation check failed because either the Oracle Inventory group could not be read from the inventory configuration file or the primary group could not be retrieved. This occurred because either the file did not exist, the property was not found, or the primary group was not found in the /etc/group file. Detailed failure information is provided in the accompanying error messages.

Action: Ensure that the inventory file exists and contains the Oracle Inventory property. On Linux and UNIX machines, verify that the primary group is found in the file /etc/group.

resolv.conf issue is caused by:

And the PRVG-10467 message does not appear in this log when I run the command as oracle!

[dfhawthorne]

Tried using networks.yml to fix DNS problem. Got the following error messages:

TASK [oracle_gi : install needed network manager libs] *************************
changed: [redfern1.yaocm.id.au] => (item=[u'NetworkManager-glib'])

TASK [oracle_gi : Configure Public LAN Interface] ******************************
fatal: [redfern1.yaocm.id.au]: FAILED! => {"changed": false, "msg": "Error: Failed to modify connection 'eth0': No such method 'Update2'\n", "name": "eth0", "rc": 1}

[dfhawthorne]

Edited /etc/sysconfig/network-scripts/ifcfg-eth0 to remove offending DNS entry (on REDFERN1)

Resolved through commit 04b2b14.

However, the PRVG-10467 message still appears while running the play-book, but not while running the cluvfy command interactively.
