Re: geo-replication unprivileged user error

I’ve tried changing the permissions to 777 on /var/log/glusterfs on all the slave nodes, but still no luck :(
here is the log from the master node where I created and started the geo-replication session.

    Geo-replication command should be run as privileged user itself.

      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.
