I need to understand the full journaling options availalble on ReiserFS and compare them against Ext3 on SuSE Linux distributions (SLES 9, NLD 9).
In either SLES 9 or NLD 9, when you create a Reiser or EXt3 file system via Yast ==> Partitioner, the journaling options under the "fstab options" button are the same (journal, ordered, writeback).
However, it is my understanding that on Linux kernels below 2.6.8 (SLES 9 and NLD 9 fall in that category), full data journaling (journal) is not an option on Reiser File System (see http://en.wikipedia.org/wiki/Comparison_of_file_systems
) . Still, the option is there on the system and you can select it and use it.
Can someone fully explain the journaling options available under ReiserFS (3.6)?
