When I was doing the technical review of Julian's book I made that point as well. Note, however, that OCFS2 advertises support for general purpose usage so in theory you can put archived redo on OCFS2 and compress them. So, then you have this really nice provisioning model: ASM for Disk Groups, RAW of CSS/OCR, Ext3 for Oracle Home and OCFS2 for archived redo.

What a mess. I blog about this
