You can select that when you are preparing your partitions. If you run the automated partitioner there is of course not much choice but you can try the manual mode. Even after that you can format individual partitions with XFS if you want. XFS is long since included in the recent linux kernels, also there is raiserfs if you feel desperate (well in fact raiser fs is ok too but you should not use it on flaky hardware). Both xfs and raiser are designed for journaling - it is believed that xfs performs better with large files and raiser good with many small files (like Maildir for example). I'd suggest a test with your data and workload to be sure. Regards Tino
