I've got some filesystems on software raid5 which is told to perform
badly without an external log not being on soft raid5. I'll set up a
raid1 volume and make another volume group of it to put all the log
volumes into it.

Some other boxes are running hardware raid (ICP Vortex oder Compaq
SmartArray 5300). But I haven't done any tuning or measurements with
them.
