RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Lon Hohberger 2016-01-14 14:26:13 UTC 
+++ This bug was initially created as a clone of Bug #1298401 +++

Description of problem:
Memcached fails to start in ipv6 environment:
overcloud-controller-0 systemd[1]: Starting Cluster Controlled memcached...
overcloud-controller-0 memcached[9948]: Invalid port number: "fd00:fd00:2000:f816:3eff:feae:9393"failed to listen on TCP port 11211: Success
overcloud-controller-0 systemd[1]: memcached.service: main process exited, code=exited, status=71/n/a
overcloud-controller-0 systemd[1]: Unit memcached.service entered failed state.

Version-Release number of selected component (if applicable):
I'm doing the test following the instructions in:
https://etherpad.openstack.org/p/tripleo-ipv6-support
and enabling pacemaker by passing an additional $THT/environments/puppet-pacemaker.yaml environment file


How reproducible:
100%

Steps to Reproduce:
1. Apply workarounds for BZ#1295986 and BZ#1297850
2. Deploy ipv6 enabled overcloud

Actual results:
systemd[1]: Starting Cluster Controlled memcached...
memcached[9948]: Invalid port number: "fd00:fd00:2000:f816:3eff:feae:9393"failed to listen on TCP port 11211: Success


Expected results:
memcached gets started

Additional info:
[root@overcloud-controller-0 ~]# cat /etc/sysconfig/memcached 
PORT="11211"
USER="memcached"
MAXCONN="8192"
CACHESIZE="15087"
OPTIONS="-l fd00:fd00:fd00:2000:f816:3eff:feae:9393 -U 11211 -t 4 >> /var/log/memcached.log 2>&1"

Assigned to OPM because I think it's a bug in puppet-memcached. We're looking at it.

--- Additional comment from Marius Cornea on 2016-01-14 06:09:46 EST ---

The issue has been reported here:
https://github.com/yeshm/memcached/issues/310

and it appears to have been solved in release 1.4.25:
https://github.com/memcached/memcached/wiki/ReleaseNotes1425

The version installed on my system is memcached-1.4.15-9.el7.x86_64
Comment 1 Lon Hohberger 2016-01-14 14:27:54 UTC 
Effectively, OpenStack can't be deployed on RHEL 7.2 using ipv6.
Comment 2 Miroslav Lichvar 2016-01-14 15:02:31 UTC 
The upstream patch applies cleanly to 1.4.15 and seems to work as expected.
