Harald, I can only give you my recommendations, I suppose.
I would have my root file system be ext3. Any file systems that are being shared read-only, I would make ext2. (If it's not mounted read-write, there's no need for journaling.) Based on a performance presentation at SHARE, there is a distinct problem with reiserfs on Linux/390 chewing up a large amount of CPU time, although the actual file system performance is quite good for lots of small files. Until that is fixed, I would avoid it. The same presentation also showed that JFS was the slowest in all cases, so I would avoid that also (for the time being). Unless you've got a specific need, I would make any non-shared r/w file systems ext3 until the problems with reiserfs get straightened out.

Some questions about filesystems to the forum, which probably will not be easily answered with yes or no ? When running a zSLES8 Linux, what choose of filesystem would fit best ? ext2,ext3,JFS,reiserFS ? ( some considerations may be . performance of operations like copy,delete,sequentiell write or read, random write or read ? . applications running like running webSphere ... . root under ext2 . converting filesystems ext2 to journaled filesystems ) I guess the answer could be, "it depends" ; but on what ?
