problem with replication (revisited)

[Chanda Unmack]

I found an old thread with my exact problem, but the resolution did not work for me.

I'm trying to replicate to a separate instance on the same server that gerrit is running on. The "slave" instance is running as a different user, but I have verified that I can do passwordless ssh from the user gerrit runs as to the user the slave is running as. I verified the permissions were correct on the ~/.ssh directory and the known_hosts file, HOME is set correctly, and that I disabled the ecdsa in the sshd_config file.

the error_log for all the projects I'm trying to replicate is:

I've tried using the hostname, localhost, user@hostname with the same result.

Running gerrit 2.5.2

I get no errors on reloading the plugin

replication config:

[remote "secondary"]

        url = ssh://hostname/${name}.git

        push = refs/heads/*:refs/heads/*

        authGroup = Replicate

I checked the box for the group Replicate so that it's visible to all registered users, and the projects that I want replicated the group Replicate has read access to refs/*

Any pointers greatly appreciated as I feel I'm missing something obvious here.

thanks!

Hi ,

Make sure you have the components necessary for replication 

./ssh/config 

Pub keys 

and test by doing an ssh to the replicant with out using a password or cahallange response .

If all those things are in place ...

I used this in the same fashion , Using ssh , 

        url = Name_of_...@example.com:/gitrepos/${name}.git/   #I had to add the trailing slash or it didnt work , and I wanted to mirror every thing , you dont have to use the push's in my example or the git style revieve pack options

        push = +refs/*:refs/*

        push = refs/changes

        push = +refs/heads

        push = +refs/meta

        push = +refs/tags

        timeout = 0

        replicationDelay = 8

        replicationRetry = 45

        receivepack = /usr/bin/git-receive-pack

        uploadpack = /usr/bin/git-upload-pack

        threads = 5

Thanks! that seems to have gotten rid of the dump, still not quite there but I think there's something amiss on the other end. Not having the log fill up with the java stack is definitely making that easier to debug.
