Re: geo-replication unprivileged user error

Aravinda <avishwan@xxxxxxxxxx> · Thu, 31 Mar 2016 13:52:29 +0530



    Hi,

    
    From the error I understood that SSH connection is failing. In
    slave-host02 extra entries present in
    /home/guser/.ssh/authorized_keys.

    
    In /home/guser/.ssh/authorized_keys Please delete extra lines which
    does not start with "command=". Then stop and start the
    Geo-replication.

    regards
Aravinda

                              I’ve been trying to setup geo-replication
                              using Gluster 3.7.3 on OEL 6.5
                              It keeps giving me faulty
                                session.
                              I’ve tried to use root user
                                instead, it works fine!
                              

                              I’ve followed literally the
                                documentation but no luck getting the
                                unprivileged user working.
                              

                              I’ve tried running /usr/libexec/glusterfs/gsyncd
                                on the slave node using
                                the unprivileged user, and that’s what I
                                get.
