This is just a preview of what has been happening in GD2, to give

GD2 can now form a cluster, list peers, create/delete,(psuedo)

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

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

ERRO[21635] Failed to add member into etcd clustererror=client: etcd

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

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

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`.

I've faced this issue intermittently, but I've never bothered checking
what caused it yet. I just nuke everything and start again.

Will do it. The whole ReST document is in need of a recheck.

What should be done to overcome this error?

Also noticed that there is a minor change in the actual response to 
/version when compared with what is documented in the API guide. We 
would need to change that.

[Gluster-users] An Update on GlusterD-2.0

[Kaushal M]

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.

We'll also be providing periodic dev builds for people to test.
Currently builds are only available for Linux on amd64. Vagrant and
docker releases are planned to make it easier to test GD2.

Thanks,
Kaushal
