container-reconciler need memcache in storage node

[Haifeng.Yan]

when I tail log, it seems that swift-container-reconciler need memcache.

This is due to the fact that the container reconciler uses the swift InternalClient to communicate inside the cluster, which uses a proxy server. If you look at your container-reconciler.conf you'll see it uses the proxy and has the cache in the pipeline. So by default yes it does use memcache.

If you don't want to use it, you can remove it from the pipeline. Or if you have a bunch of memcache servers your are already using, define them in /etc/swift/memcache.conf and drop this file on all servers that needs memcache hosts defined.

So we should edit the manuals, add a step to install memcache in storage node or remove it from pipeline in the default configure file to avoid this error.

Should be fixed here: http://docs.openstack.org/kilo/config-reference/content/container-reconciler-configuration.html

Haifeng,

Could you please let me know what instructions you were following to reach this result?

Thank you,
