[Gluster-users] Gluster 3.6.4 peer rejected while doing probe

[Davy Croonen]

Hi all

We have a production cluster with 2 nodes (gfs01a and gfs01b) in a distributed replicate setup with glusterfs 3.6.4. We want to expand the volume with 2 extra nodes (gfs02a and gfs02b) because we are running out of diskspace. Therefor we deployed 2 extra nodes with glusterfs 3.6.4.

Now, while probing the 2 new nodes from a node in the existing cluster we got the following error:

root at gfs01a-dcg:~# gluster peer probe gfs02a-dcg.intnet.be<http://gfs02a-dcg.intnet.be>
peer probe: success.

In the log file /var/log/glusterfs/etc-glusterfs-glusterd.vol.log the following entries are written:

The exact same error appears while probing the second node (gfs02b).

Anyone any idea how to solve this?

Thanks in advance.

Kind regards
Davy
