But now I have strange issue:
After creating the geo-rep session and starting it (from nodeB):
[root@nodeB]# gluster vol geo-replication myvol slaveA::myvol status detail

So.
1/Why there is 3 masters nodes ??? nodeB should be the master node only
2/Why it kept changing turn by turn from active to passive?
Thanks

On slaveA I have the common pem file transfered in /v/l/g/geo/ with my 3 nodes

But the /root/.ssh/authorized_keys is not populated with this file.

I have for now only one node on my remote site.
Any way, as this step is done to copy the file accros all the cluster member I

The only difference is State: Peer is connected and Accepted (Connected) from
nodeB about nodeA
When I execute gluster system from node A or C, I have the 3 nodes keys in
common pem file. But from nodeB, I only have keys for nodeB and node C. This is
infortunate as I try to launch the georeplication job from nodeB (master).

So,
On master node of my 3 node setup:
1) gluster system:: execute gsec_create
in /var/lib/glusterd/geo-replication/common_secret.pub I have pem pub key from
master node A and node B (not node C).
On node C in don’t have anything in /v/l/g/geo/ except the gsync template
config.
So here I have an issue.
The only error I saw on node C is:

On node A, the cli.log looks like:

If I run gluster system:: execute gsec_create on node C or node B, the common
pem key file contains my 3 nodes pem puk keys. So in some way node A is unable
to get the key from node C.
So let’s try to fix this one before going further.

Hi,
I’m ready for new testing, I delete the geo-rep session between master and
slace, remove the lines in authorized keys file on slave.
I also remove the common secret pem from slave, and from master. There is only
the gsyncd_template.conf in /var/lib/gluster now.
Here is our setup:
Site A: gluster 3 nodes
Site B: gluster 1 node (for now, a second will come).
I can issue
gluster systen:: execute gsec_create
what to check?
common_secret.pem.pub is created in
/var/lib/glusterd/geo-replication/common_secret.pem.pub, which should contain
public keys from all Master nodes(Site A). Should match with contents of
/var/lib/glusterd/geo-replication/secret.pem.pub and
/var/lib/glusterd/geo-replication/tar_ssh.pem.pub.
then
gluster geo vol geo_test slave::geo_test create push-pem force (force is needed
because the slave vol is smaller than the master vol).
What to check ?
Check for any errors in, /var/log/glusterfs/etc-glusterfs-glusterd.vol.log in
rpm installation or in
/var/log/glusterfs/usr-local-etc-glusterfs-glusterd.vol.log if source
installation. In case of any errors related to hook execution, run directly the
hook command copied from the log. From your previous mail I understand their is
some issue while executing hook script. I will look into the issue in hook
script.
I want to use change_detector changelog and not rsync btw.
change_detector is crawling mecanism. Available options are: changelog and
xsync. xsync is FS Crawl.
sync mecanisms available are: rsync and tarssh.
Can you guide me to setup this but also debug why it’s not working out of the
box ?
If needed I can get in touch with you through IRC.
Sure. IRC nickname is aravindavk.
Thanks for your help.
