Hello,
given a geo-replicated file of 20 GBytes in size.
If one byte in this file is changed, what will be transferred ?
- the changed byte
- the block/sector the containing the changed byte
- the complete file
Gluster Geo-replication uses Changelog for detecting the new or modified files list after the last sync. Once the list of files is available, then it passes that list of Rsync jobs. Which internally calculates the delta changes and sync only those delta changes.
Note: Geo-replication syncs complete file if the use-tarssh option is set to true.
Is the storage mode relevant - sharded/striped/... ?
If the Master volume is sharded, then Remote/Slave volume also should be sharded Volume. Geo-rep is intelligent to detect the changes to the sharded files and sync only those files.

Petric
