[Gluster-users] Geo-Replication push-pem actually does'nt append common_secret_pub.pem to authrorized_keys file

Wed Jan 21 18:57:36 UTC 2015

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:

[2015-01-21 18:36:41.179601] E [rpc-clnt.c:208:call_bail] 0-management: bailing out frame type(Peer mgmt) op(—(2)) xid = 0x23 sent = 2015-01-21 18:26:33.031937. timeout = 600 for xx.xx.xx.xx:24007

On node A, the cli.log looks like:

[2015-01-21 18:49:49.878905] I [socket.c:3561:socket_init] 0-glusterfs: SSL support is NOT enabled

[2015-01-21 18:49:49.879085] I [socket.c:3561:socket_init] 0-glusterfs: SSL support is NOT enabled

[2015-01-21 18:49:49.972143] I [input.c:36:cli_batch] 0-: Exiting with: 0

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.
