Hi all, I found this doc on georeplication. I am on gluster 3.9. I am looking for documentation that explains how to failover between the master and slave volumes.
http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Geo%20Replication/ How would someone handle the following scenario. 1. two datacenters A and B. Each is running a gluster pool. 2. In DC A , create gluster volume named gv0-dcA. 3. In DC B, create gluster volume named gv0-dcB. 4. Gluster volume gv0-dcA is the master and volume gv0-dcB is the slave. 5. A couple GB of data is written to gv0-dcA and replicated to gv0-dcB. 6. Initiate failover process so that: 1. all writes are completed on gv0-dcA 2. gv0-dcA is now read-only 3. gv0-dcB becomes master and now data can be written to this volume 4. gv0-dcA is now the slave volume and gv0-dcB is the master volume. Consequently, georeplication now happens from gv0-dcB to gv0-dcA. 7. repeat all steps described in the previous step but now roles are switched where gv0-dcA becomes master and gv0-dcB becomes slave. Thanks, Joe
