[Gluster-users] unable to get Geo-replication working

Fri Apr 27 16:45:55 UTC 2012

Are you trying to setup geo-replication between gluster voolume ->
non-gluster volume? or is it between gluster volume -> gluster volume?

It looks like there might be some configuration issue here. Please give
your script of how you configured geo-replication?
