Description Sabina Aledort 2021-04-18 13:07:34 UTC 
Version: 4.8.0-0.nightly-2021-04-18-073623

$ openshift-install version
4.8.0-0.nightly-2021-04-18-073623

Platform:
baremetal

Please specify: IPI

What happened?

When installing a new baremetal IPI cluster, one of the masters came up as localhost.localdomain.

[root@cnfdc2-installer ~]# oc get node
NAME                                             STATUS     ROLES    AGE   VERSION
dhcp19-17-121.clus2.t5g.lab.eng.bos.redhat.com   NotReady   master   26m   v1.21.0-rc.0+2993be8
dhcp19-17-122.clus2.t5g.lab.eng.bos.redhat.com   NotReady   master   26m   v1.21.0-rc.0+2993be8
localhost                                        NotReady   master   20m   v1.21.0-rc.0+2993be8

What did you expect to happen?

All 3 masters should appear with their proper fqdn.

We had a similar bug in 4.7 that was fixed:

Adding cluster must-gather and journalctl log from the 'localhost' node.

It is happening in other clusters as well.

I also have the same bug.

[root@cnfdt08-installer ~]# openshift-baremetal-install version
openshift-baremetal-install 4.8.0-0.nightly-2021-04-19-071934


[root@cnfdt08-installer ~]# oc get node
NAME                                  STATUS   ROLES            AGE   VERSION
dhcp-55-218.lab.eng.tlv2.redhat.com   Ready    master,virtual   22h   v1.21.0-rc.0+2993be8
localhost                             Ready    master,virtual   22h   v1.21.0-rc.0+2993be8


I've attached the log from the bootstrap VM.

The file was too big to attach, so here's a link to it in my GDrive.

Comment 8 Ben Nemec 2021-04-20 16:19:12 UTC 
This is the same bug as the 4.7 one. The fix is still in review, which is why you're still seeing the problem. This should go away once the fix merges.
