[Gluster-users] 3.6.2 geo-replication session created but no files are copied

[Sander Zijlstra]

LS,

Last week I configured geo-replication between two glusterFS clusters, both version 3.6.2 and all looks ok:

[root at s35-06 gv0]# gluster volume geo-replication gv0 status

MASTER NODE MASTER VOL    MASTER BRICK                      SLAVE         STATUS     CHECKPOINT STATUS    CRAWL STATUS

s35-07    gv0           /glusterfs/bricks/brick1/brick    v39-app-02::gv0    Passive    N/A                  N/A
s35-09    gv0           /glusterfs/bricks/brick1/brick    v39-app-04::gv0    Passive    N/A                  N/A
s35-08    gv0           /glusterfs/bricks/brick1/brick    v39-app-01::gv0    Active     N/A                  Changelog Crawl

I started the replication at the end of the day, hoping that all 40TB would be copied by the next day or so, but I discovered that not a single bit has been copied.

When looking at the volume config settings I found the “ssh command” used so I tried that and discovered the following issue between my master and slave cluster when executing the configured “ssh command"

[root at s35-06 gv0]# ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i /var/lib/glusterd/geo-replication/secret.pem v39-app-01

Connection to v39-app-01 closed.

Can somebody point me to how to fix this “gsycnd” issue? I didn’t find any updated packages from CentOS for my release (6.6), so I expect it should be a working setup.

any help would appreciated

Met vriendelijke groet / kind regards,
