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

[Gaurav Garg]

Hi Adrian,

Did you try to upgrade/downgrade gluster03 before performing any operation. If you attach fresh node (3.6.3 version) to (3.6.2) glusterfs version then this problems is not coming. we need to know what operation you performed on gluster03 node before peer probe. if possible could you attach cmd_history.log and glusterd log.

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 ": 



[2015-05-11 06:59:39.035184] D [glusterd-peer-utils.c:121:glusterd_peerinfo_find_by_hostname] 0-management: 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

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.
