I configured both servers as master/slave in cross, with different sync_machineid ( for UID computation ) and guid_mode: sha1. I tested this scenario, and it's working great. Changes on one server are replicated to the other one, and this in both directions. > >> There are tools like nake_md5 and make_sha1, but the manpages document >> only howto config them, but not how to realy use them for replication >> check. > > I download the md5 files to a single location and run a 50 line Perl > script to spot mismatches. You are welcome to a copy of that script. Yeah ... cann you mail me a copy for inspiration ??
