Hi, I am working on a replication tool for lustre filesystems.
We have introduced a mechanism for getting the changes that have been made to a lustre filesystem - similar to inotify. We call this mechanism, changelogs. For performing replication, we open the source file using its 'file identifier' or FID (think of it an inode that is unique cluster wide) instead of its path. The file is then replicated to the target. We would like to use rsync to do this data copy. I was investigating ways to pass a stream of filenames to rsync. It would seem that we cannot use '--files-from' as we copy from $SRC/.lustre/$FID to $DST/path/to/file. Is there a way of passing a list of source _and_ destination paths?? It would have been even better if there were a rsync library that our replication tool could link to, instead of passing a list of files. The librsync project on sourceforge (librsync.sourceforge.net) seems to be unmaintained. Does anyone on this list have any experience with using rsync as a library?
