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.
