Comment 2 Aravinda VK 2015-06-11 10:53:06 UTC
This happens only when "root@slavehost::slavevol" is used in Geo-rep create command instead of just "slavehost::slavevol".

Comment 6 Rahul Hinduja 2015-07-07 14:29:15 UTC
Verified with build: glusterfs-3.7.1-7.el6rhs.x86_64

(a) Created geo-rep session using root@slave-host::slave-vol 
(b) Started geo-rep session
(c) Paused geo-rep session
(d) Created Snapshot
(e) Listed Snapshot
(f) Activated snapshot
(g) Resumed geo-rep session

All above were successful. Moving the bug to verified state.

Comment 8 Kotresh HR 2015-07-09 09:12:33 UTC
The issues is surfaced only because of RHSC support of geo-replication. Hence giving Doc_text -
