As I said at the first submission, I plan to add such features to the new dm-snapshot code. Then we can have simple user-space code that focus on the replication. A daemon program requests delta from the kernel, and sends it to another daemon program on the remote server. The daemon on the remote server asks the kernel to apply delta. The advantage of this approach, the above replication program can work with any snapshot implementation, which could live in dm or file systems like btrfs. File systems could implement the snapshot features more efficiently than dm. My question related with this issue is, any chance to modify Zumastor's ddsnapd in a such way. Well, I guess, it would be better to ask on Zumastor mailing list. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
