shouldn't. I usually see only a journal control

Remember meta-data journaling is fairly common. Data journaling much less so. Data journaling will be more robust, so if robustness is your issue, give it a shot. I don't know what filesystems offer data journaling, but ext3 definitely does. From the main page in the ext3 section: ============== data={journal|ordered|writeback} Specifies the journalling mode for file data. Metadata is always journaled. To use modes other than ordered on the root filesystem, pass the mode to the kernel as boot parameter, e.g. rootflags=data=journal. journal All data is committed into the journal prior to being written into the main filesystem. ordered This is the default mode. All data is forced directly out to the main file system prior to its metadata being committed to the journal. writeback Data ordering is not preserved - data may be written into the main filesystem after its metadata has been committed to the jour‐ nal. This is rumoured to be the highest-throughput option. It guarantees internal filesystem integrity, however it can allow old data to appear in files after a crash and journal recovery. ================ writeback is the least robust. Data can be written in any order and conceivably sit in cache for extended periods. 5+ years ago, I think this was the normal behavior for most mainstream filesystems. ext3 now defaults to data=ordered (Remember the journals are flushed on every mount, so it is easy to switch from one mode to another.) I don't know if "data=journal" is any safer than "data=ordered" or not.
