[Gluster-users] Adding a 3.6.3 peer to a 3.6.2 trusted pool fails

[Adrián Santos Marrero]

Hi,

I've been trying to add a third node to my two-node trusted pool with
gluster peer probe:

gluster02:~# gluster peer probe gluster03.stic.ull.es
> peer probe: success.
>

The problem is that this node remains in "Accepted peer request" state:

Hostname: gluster03.stic.ull.es
> Uuid: 9ca23fb2-cd76-4d1c-8a5f-f93306119539
> State: Accepted peer request (Connected)
>

If I restart glusterd in gluster02, the state changes to "Sent and Received
peer request":

Hostname: gluster03.stic.ull.es
> Uuid: 9ca23fb2-cd76-4d1c-8a5f-f93306119539
> State: Sent and Received peer request (Connected)
>

And if I restart glusterd in gluster03 it doesn't start because is "Unable
to find friend: gluster01.stic.ull.es":

In fact, the only peer that gluster03 knows is gluster02:

gluster03:~# ls -l /var/lib/glusterd/peers/
> total 4
> -rw-------. 1 root root 73 may 11 07:48
> 739d7c3f-99d5-4c8b-ac28-f85163e26322
> gluster03:~# cat
> /var/lib/glusterd/peers/739d7c3f-99d5-4c8b-ac28-f85163e26322
> uuid=739d7c3f-99d5-4c8b-ac28-f85163e26322
> state=5
> hostname1=10.107.34.18
>

10.107.34.18 == gluster02

gluster03:~# gluster --version
> glusterfs 3.6.3 built on Apr 23 2015 16:11:45

All servers are running Centos 7, gluster01 and gluster02 have Gluster
3.6.2 version and gluster03 3.6.3.

Am I forced to upgrade gluster01 and gluster02 to 3.6.3?

Regards.
