You can check the glusterd log files on a pair of peers to understand what's happening. Output of "gluster peer status" can also help in determining if there is a network problem. HTH, Vijay

[Gluster-users] Unable to peer probe between new servers and old servers
> You can check the glusterd log files on a pair of peers to understandwhat's happening. I wish I understood what's happening. What is dumped out in /var/log/glusterfs/cli.log appears about as useful as a Windows blue screen of death. I'm not sure what you mean by "A pair of peers". I have two pairs that communicate, web1 <-> web2 (old servers), and web3 <-> web4 (new servers). When I do a "gluster peer probe" from A to B, nothing ever appears in the log file of B; it does not matter if the peer is successful or not. I've posted the output from cli.log from the failing "gluster peer probe" server. ----------------------------------------------- root at web1:/# gluster peer status ----------------------------------------------- Number of Peers: 1 Hostname: web2 Uuid: a7ec2afb-d3fc-4b00-891f-93d2df40c97a State: Peer in Cluster (Connected) ----------------------------------------------- root at web2:/# gluster peer status ----------------------------------------------- Number of Peers: 1 Hostname: 10.10.X.X Uuid: 87a71cfc-3b84-4163-b4bf-c5ebc07d7338 State: Peer in Cluster (Connected) ----------------------------------------------- root at web3:/# gluster peer status ----------------------------------------------- Number of Peers: 1 Hostname: web4 Uuid: 8e427da7-67e3-40d7-9143-a500b630ae34 State: Peer in Cluster (Connected) ----------------------------------------------- web4 at neo:/# gluster peer status ----------------------------------------------- Number of Peers: 1 Hostname: 10.11.X.X Uuid: 0df7c7d8-bf8e-4c00-91aa-809990b032ce State: Peer in Cluster (Connected) Other names: web3 ---------------------------------------------- On Thu, Jan 8, 2015 at 10:03 AM, Vijay Bellur <vbellur at redhat.com> wrote:> On 01/08/2015 11:21 PM, Michael Bushey wrote: > >> On web1 and web2 I purged the gluster packages, did an "rm -rf >> /etc/glusterd /var/lib/glusterd" and then "apt-get install >> glusterfs-client glusterfs-server".
