The first preview/dev release of GlusterD-2.0 is available now. A
prebuilt binary is available for download from the release-page[1].

This is just a preview of what has been happening in GD2, to give
users a taste of how GD2 is evolving.

GD2 can now form a cluster, list peers, create/delete,(psuedo)
start/stop and list volumes. Most of these will undergo changes and
refined as we progress.

More information on how to test this release can be found on the release
page.

We'll providing periodic (hopefully fortnightly) updates on the
changes happening in GD2 from now on.



Thank you for posting this, Kaushal!

I was trying to add a peer using the gluster/gluster-centos docker
containers and I encountered the following error:

INFO[17533] New member added to the cluster               New member
=ETCD_172.17.0.3 member Id =b197797611650d60

INFO[17533] ETCD_INITIAL_CLUSTER_STATE"existing"
ERRO[17540] Failed to add peer into the etcd store        error=client: etcd

ERRO[21635] Failed to add member into etcd cluster        error=client: etcd
cluster is unavailable or misconfigured member=172.17.0.3

These 2 errors are from etcd-client, which mean that the GD2 cannot
connect to the etcd server.
As the errors indicate, it could be because the etcd daemon isn't
running successfully,
or because etcd hasn't successfully connected to its cluster. There
could be more information in the etcd log under
`GD2WORKDIR/log/etcd.log`.


From etcd.log:

2016-09-29 04:53:45.379924 W | etcdserver: cannot get the version of member b197797611650d60 (Get http://172.17.0.3:2380/version: dial tcp 172.17.0.3:2380: getsockopt: connection refused) 2016-09-29 04:53:49.380374 W | etcdserver: failed to reach the peerURL(http://172.17.0.3:2380) of member b197797611650d60 (Get http://172.17.0.3:2380/version: dial tcp 172.17.0.3:2380: getsockopt: connection refused)

It does look like a firewall issue. I will resolve that and check.

Thanks,
Vijay
