Description Vedashree Deshpande 2023-03-22 11:06:58 UTC

Description of problem:
As of now, we do not check in health check if Satellite FQDN is set or not. So before configuring new  DNS, DHCP or updating certificates we should have foreman-maintain health check run and it should check proper FQDN. 

Version-Release number of selected component (if applicable):
6.10 onward

Actual results:
# foreman-maintain health check
Running ForemanMaintain::Scenario::FilteredScenario
================================================================================
Clean old Kernel and initramfs files from tftp-boot:                  [OK]

--------------------------------------------------------------------------------
Check to verify no empty CA cert requests exist:                      [OK]
--------------------------------------------------------------------------------
Check whether system is self-registered or not:                       [OK]
--------------------------------------------------------------------------------

Expected results:
It should include hostname check.

We can check and verify the outputs of

$ hostnamectl status
$ ping -c1 hostname -f
$ ping -c1 localhost

Comment 3 Sayan Das 2023-05-09 15:34:11 UTC

I was discussing this BZ with Vedashree as I was a bit confused. But after discussing with her, I believe the right intention here is :

* A hostname check should be included in the foreman_maintain's health check code:

* The *check* should be able to 

  * Check the current FQDN
  * Check the FQDN recognized by satellite ( i.e. in the configuration of satellite )
  * Verify that both FQDN matches with each other
  * If they don't, print both the FQDNs and request user to fix that mismatch. 

In that way, A manual OS level change in FQDN or change in the domain of the host can be easily detected.
