More informations here:
I update the state of the peer in the uid file located in /v/l/g/peers from state 10 to state 3 (as it is on other node) and now the node is in cluster.
gluster system:: execute gsec_create now create a proper file from master node with every node’s key in it.
Now from there I try to create my georeplication between master nodeB and slaveA
gluster vol geo myvol slave::myvol create push-pem force
From slaveA I got this error message logs:
[2015-02-02 17:19:04.754809] E [glusterd-geo-rep.c:1686:glusterd_op_stage_copy_file] 0-: Op Version not supported.

On slaveA I have the common pem file transfered in /v/l/g/geo/ with my 3 nodes from source site.
But the /root/.ssh/authorized_keys is not populated with this file.
From the log I saw that there is a call to a script
/var/lib/glusterd/hooks/1/gsync-create/post/S56glusterd-geo-rep-create-post.sh —volname=myvol is_push_pem=1 pub_file=/var/lib/glusterd/geo-replication/common_secret.pem.pub slave_ip=salveA
In this script the following is done:
```
scp $pub_file $slave_ip:$pub_file_tmp
ssh $slave_ip "mv $pub_file_tmp $pub_file"
ssh $slave_ip "gluster system:: copy file /geo-replication/common_secret.pem.pub > /dev/null"
ssh $slave_ip “gluster system:: execute add_secret_pub > /dev/null"
```
The first 2 lines passed, the third fail so the fourth is never executed.
Third command on slaveA
#gluster system:: copy file /geo-replication/common_secret.pem.pub
One or more nodes do not support the required op version.
# gluster peer status
Number of Peers: 0

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 can deal without
The fourth command is not working:

Every node is connected:

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).

Looks
like node C is in diconnected state. Please let us know the output of `gluster peer status` from all the master nodes and slave nodes.

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.
