Re: Geo-replication (v3.5.3)

[John Gardeniers <jgardeniers@xxxxxxxxxxxxxxxxx>]

Just to make it clear, I *have* set up passwordless SSH between the node where I'm running the command and the slave. I thought that should have been obvious from my message. Also, the identity files are in the standard location. So, back to the question I asked, What gives? More to the point, how do I make this work?

Using Gluster v3.5.3 and trying to follow the geo-replication instructions (https://github.com/gluster/glusterfs/blob/master/doc/admin-guide/en-US/markdown/admin_distributed_geo_rep.md), step by step, gets me nowhere.

The slave volume has been created and passwordless SSH is set up for root from the master to slave. Both master and slave volumes are running.

Running "gluster system:: execute gsec_create", no problem.
Running "gluster volume geo-replication <master_volume> <slave_host>::<slave_volume> create push-pem [force]" (with appropriate parameters, with and without "force") results in "Passwordless ssh login has not been setup with <slave_server>. geo-replication command failed"

As I said, passwordless SSH *is* set up. I can SSH from the master to the slave without a password just fine. What gives? More to the point, how do I make this work.

Just to make it clear, password less ssh needs to be setup between the master node where you run the "geo-rep-create" command to slave node specified in the "geo-rep-create" command.

And if you have identity file saved in non-standard location, geo-rep had a bug for it https://bugzilla.redhat.com/show_bug.cgi?id=1181117

The patch is set for it and should be available in next release of glusterfs.
