Corruption due to fsync being off on the master will be replicated to
the slave, or - if corruption is bad enough - replication will fail to
replicate affected records entirely. Of course, turning fsync off is
no guarantee for corruption - it's the other way around: having it on
guarantees that you don't get corruption (provided that... etc).

You could disable replication while fsync is off. I'd verify the data
on the master (by creating a dump, for example) before re-enabling it
again, though.
