Please let us know the version of GlusterFS you are using. Do you see any errors in the log files about sync failure?(Logs will be in /var/log/glusterfs/geo-replication dir in each master nodes and /var/log/glusterfs/geo-replication-slaves in each slave nodes)

Hello all,

we try to setup a geo-replication for a volume with 200.000 Folders and
about 1.500.000 evenly distributed small files. The geo-replication is build
over a VPN connection.

Initially when the geo-replication starts, both sides have the same files
and directories. Randomly written files on side A appears after some
seconds on the other side B. The write load is about 200.000 small files
per day. All works as expected.

We facing a problem when the VPN Connection has an issue for some
minutes. During the connectivity problem the file write on side A is ongoing.

After the connectivity is stable again the geo-replication is not able
to get both sides in sync again.

Is this behavior already known?
