Gluster users - Aug 2015 - How to resynchronize geo-replication slave after crash

Hi All,

I have a geo-replication master - slave.
The slave had some troubles and the replication was not working for a 
certain time. What I did:

* Manual rsync to synchronize master and slave
* Start geo-replication

It seems the new files are not synchronized correctly.
Is there a procedure how to do a full sync with GlusterFs and continue 
with replication?

Thank you.

Hi Milos,

Geo-replication expects gfids of files between master and slaves to be same for
the data syncing.
Interfering the geo-rep sync by any kind of manual methods that could change the
gfids is not
recommended and data for those files will not be synced.

To bring back to the sane state, those file which are manually synced through
rsync which has different
gfids must be removed.

Method to Initiate a Full sync depends on version being used.

Which gluster version are you using?

Thanks and Regards,
Kotresh H R
