[Gluster-users] geo-replication {error=12} on one primary node

I,m still testing and I found that I can force the error by changing the 
shell from the unprivileged user, on the secondary node, from bash to 
sh. In the  first try I used "useradd -G geogruppe -m geobenutzer" so my 
user gets /bin/sh (the dash) as default shell. Then the error occurs. 
Then I switch the user to /bin/bash and the error is gone. After the 
test with the default shell I removed rsync to look for the error. So 
now I tested with /bin/bash as default shell but without rsync is 
installed. And I got:

as expected. Reinstalling rsync and everything is fine again :-). So the 
{error=12} came from /bin/sh as default shell. The missing rsync was not 
shown because geo-replication changed to faulty before rsync was used.
