[Gluster-users] 3.6.2 geo-replication session created but no files are copied

Wed Apr 8 07:18:41 UTC 2015

Aravinda,

I wasn’t really referring to the SSH command itself but the error thrown by gsyncd.py:

>> error: incorrect number of arguments
>> 
>> Usage: gsyncd.py [options...] <master> <slave>

The status is still like this:

# gluster volume geo-replication gv0 v39-app-01::gv0 status

MASTER NODE                 MASTER VOL    MASTER BRICK                      SLAVE                                        STATUS     CHECKPOINT STATUS    CRAWL STATUS
