Description Thom Carlin 2016-02-15 20:06:53 UTC

Description of problem:

dracut emergency shell, journalctl reports dhclient errors

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

RHCI TP2 RC9

How reproducible:

Intermittent but frequent

Steps to Reproduce:
1. Install both RHCI and TripleO ISOs
2. Log in each system to run launch-fusor*-installer
3. Deploy OpenStack + CloudForms using RHCI

Actual results:

Overcloud nodes sometimes register, sometime go to dracut emergency shell

Expected results:

All Overcloud nodes consistently register

Additional info:

Same hardware worked fine earlier today.
journalctl displays "can't create /var/lib/dhclient/dhclient.leases: No such file or directory" several times

This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

Comment 6 Dmitry Tantsur 2016-09-06 15:53:22 UTC

Hello,

The dhclient error is not fatal, please look for a real failure. Also what do you mean by "register"? I'm not sure I'm familiar with a product/project you're using with RHOS.

Comment 7 Thom Carlin 2016-09-07 11:17:37 UTC

As mentioned, this is fatal from an end-user's perspective.

For information on QCI (a.k.a. RHCI), please see https://access.redhat.com/documentation/en/quickstart-cloud-installer/1.0/paged/quickstart-cloud-installer-guide/, especially Section 4.2

Comment 8 Dmitry Tantsur 2016-09-07 11:46:39 UTC

No, the "can't create leases" is NOT fatal on its own, I see it on all my machines. Could you please undig the whole journalctl? Also it's still unclear to me if it happens during introspection or during deployment. I suspect the former, but please clarify as well.

Comment 9 Thom Carlin 2016-09-07 11:55:09 UTC

That environment was transient and removed back in February so no journalctl is currently available.  Since then, there have been several rewrites to the application.

I believe your latter question is from a TripleO perspective (as opposed to a QCI perspective) so I would say introspection.  The terms have different meanings, depending on the context.

Comment 10 Dmitry Tantsur 2016-09-07 12:30:49 UTC

So, do you still experience this problem? If not, we probably won't be able to fix it, as we need a reproducer.

Comment 11 Thom Carlin 2016-09-20 11:19:10 UTC

I have not experienced this recently.

Comment 12 Dmitry Tantsur 2016-09-21 10:10:54 UTC

OK, thanks, please reopen if you see it again.
