Description mathieu bultel 2015-08-27 10:01:37 EDT
Description of problem:

When doing a yum update from the GA release of Director to the latest poodle (or latest puddle).
yum is hanged on the cleanup of nova-compute package.

No timeout appear with ssh or yum ... still waiting infinitely.. (I let it wait for few hours...)

Reproducible : 100%

The workaround is to stop services :

        - openstack-nova-api.service
        - openstack-nova-compute.service
        - openstack-ironic-api.service
        - openstack-ironic-discoverd.service
        - openstack-ironic-conductor.service
Comment 3 Zane Bitter 2015-09-03 12:39:42 EDT
With any luck this will be fixed by the integration between yum and puppet that we already have planned. Either way, we'll need to retest once that stuff has landed.
Comment 4 Prasanth Anbalagan 2015-09-14 10:14:51 EDT
Verified as follows. No hang of yum process was observed.

Mathieu, can we try removing the workaround for this from the CI script and confirm that it is fixed that way also?
Comment 7 errata-xmlrpc 2015-10-08 08:17:48 EDT
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.

For information on the advisory, and where to find the updated
files, follow the link below.

If the solution does not work for you, open a new bug report.

Comment 8 mathieu bultel 2015-11-05 11:43:36 EST
I hit this bug again in CI, since I used the GA image to update to the latest puddle.
I re-enabled the workaround which consist to stop nova-api / nova-compute / ironic-api / ironic-conductor and discoverd
Comment 9 Zane Bitter 2015-11-05 12:01:42 EST
Are you hitting this on the controller or the compute nodes? It definitely should not be happening on the controller, because we use Pacemaker to stop all the services before running yum update. The compute nodes use Puppet to do the update, so there may be more to investigate there.
Comment 10 mathieu bultel 2015-11-05 12:04:24 EST
it's during the yum update of the undercloud
Comment 11 Zane Bitter 2015-11-05 13:02:43 EST
Oh, the *undercloud*. We might just need to document this as one of the steps then.

to be clear the workaround here is to stop those services before running yum update on the undercloud?

if so, can you also let me know what the new version of rabbitmq-server is that you ended up with after the update?

my suspicion is that this might the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1264083 as i've seen some openstack services hang and not get restarted gracefully if rabbitmq goes away before.
Comment 13 mathieu bultel 2015-11-06 10:47:10 EST
The version on the undercloud after the update is :

Seems related ...
Comment 14 Mike Burns 2015-11-07 02:14:17 EST
This is identical to bug 1264083.  The solution is to update rabbitmq-server first, restart rabbitmq-server, then yum update everything else.  Omri has verified that this works for him and will be documented as part of the update kbase.
