            Bug ID: 1482877
           Summary: Extended attributes not supported by the backend
                    storage
           Product: GlusterFS
           Version: 3.11
         Component: geo-replication
          Assignee: bugs at gluster.org

Description of problem:
Geo-replication session becomes faulty after a while of syncing.


Version-Release number of selected component (if applicable):
3.11.2-1

How reproducible:
Setup a session for geo-replication between a local site and a remote one to
sync two volumes. Both backend storages are EXT4. The data is backups of
servers containing many hard and sumlinks.

Actual results:
The geo-replication session becomes faulty at the same exact point every time I
try.

Expected results:
The sync should finish with no errors.
