I understand LVM mirrors do it on an extent basis. But what would be really appropriate for this application is inter-mezzo: keeping the FS transaction log and using that to tell what to send to the other replica sounds like the right way to do this kind of synchronization. Too bad inter-mezzo is dead :-( -- Alexandre Oliva http://www.ic.unicamp.br/~oliva/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org}
