YMMV. > I personally am a fan of XFS. However, it is also possible to use ext3 on large partitions, as you point out. At work, I have a production server (running RHEL, unfortunately) which is serving up a 6 TB filesystem. I took to reading up on ext3 and judiciously set things like the block size and some of the other filesystem parameters so that crash recovery would not take ages and so that performance would be a bit better. Of course, since Debian supports both XFS and JFS quite nicely, I would opt for one of those.
