hi all,

I want to know some more detail about glusterfs georeplication, more about syncdeamon, if 'file A' was mirorred in slave volume , a change happen to 'file A', then how the syncdeamon act?

1. transfer the whole 'file A' to slave 

2. transfer the changes of file A to slave

Gluster Geo-replication uses Changelogs to detect the changes happened in the Volume. With this crawling is not required to detect the modified/created files after last sync. Once the changes are detected it calls Rsync command with predefined list of files.(--files-from argument of rsync). Rsync will take care of syncing only delta changes to target Volume.

Let us know if you have more queries about Geo-replication.

thx lot
