            Bug ID: 1276839
           Summary: Geo-replication doesn't deal properly with sparse
                    files
           Product: GlusterFS
           Version: 3.6.1
         Component: geo-replication
          Assignee: bugs at gluster.org

Description of problem:
Without '--sparse' option tar will not properly archive sparse file
and geo-replication will result in non-sparse file on the remote end.


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


How reproducible:
Every time you have sparse files to geo-replicate the remote end will have
files full size and not sparse anymore.

Steps to Reproduce:
1. Copy a sparse file into a volume.
2. Wait for geo-replication to copy it to remote cluster.
3. Check the files on the remote end. It's no longer sparse.

Actual results:
Sparse files are no longer sparse after being geo-replicated.

Expected results:
Sparse files must remain sparse after being geo-replicated.

Additional info:
Here is more on how I arrived at this
