+ help
+ The journal mode options for ext3 have different tradeoffs
+ between when data is guaranteed to be on disk and
+ performance. The use of "data=writeback" can cause
+ unwritten data to appear in files after an system crash or
+ power failure, which can be a security issue. However,
+ "data=ordered" mode can also result in major performance
+ problems, including seconds-long delays before an fsync()
+ call returns. For details, see:
+
+ http://ext4.wiki.kernel.org/index.php/Ext3_data_mode_tradeoffs
+
+ If you have been historically happy with ext3's performance,
+ data=ordered mode will be a safe choice and you should
+ answer 'y' here. If you understand the reliability and data
+ privacy issues of data=writeback and are willing to make
+ that trade off, answer 'n'.
