You can reboot the slave without stopping geo-replication. If you do this, geo-rep session status would turn faulty and geo-rep would try to connect to the slave periodically. After the slave node is back online, things would be fine thereafter. > > When the slave is rebooted is a full re-crawl / re-sync needed or will it > just pick up where it left off?

In this case it’s good to stop the geo-rep session. After it’s back up, it will continue from where it left off. No full crawl is required. OTOH, do you plan to use slave (for writes, etc.) when master is offline? In that case geo-rep supports failover-failback, where a reverse sync (from slave to master) can be done efficiently. > > Thanks > > J. > _______________________________________________ > Gluster-users mailing list > [email protected] > http://supercolony.gluster.org/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
