We're currently setting up a new MySQL 5.5 replicated database using NFS mounts for the database. The standard configuration for MySQL replication includes setting "innodb_flush_log_at_trx_commit=1" and "sync_binlogs=1" to make sure database updates are saved and replicated properly in the case of a server crash, or power outage. My question is regarding NFS. If we store the databases for the replicated servers on NetApp NFS mounts, are we still guaranteed that the updates are saved properly even with "innodb_flush_log_at_trx_commit=1" and "sync_binlogs=1"? I've read two NetApp documents "Best Practices Guidelines for MySQL" and "MySQL 5.0 Performance Protocol Comparision", but there is nothing I can find that talks specifically about NFS and MySQL Replication.
