that was only a temporary solution for RAC untill OCFS came along and
now it has become the recommended way of doing things. I see no point in
mucking about with RAW devices, expecially if they are not going to be
supported, as some LKML threads suggested.


"temporary"? Back in '99 Oracle wouldn't have had it any other way. When we
(Sun MDE) did benchmarks of E10k for Amdocs it was all about how to shift
RAID volumes and Oracle database/index/log "partitions" around to maximize
performance.

Anyway, now that OCFS is out and about - would it be recommended for other
databases besides Oracle or is it too Oracle-specific?

(side note - I'm reading linux/Documentation/vfs.txt to see how I can
implement a tiny addition to procfs and had this brilliant idea for yet
another db-specific filesystem but you seem to trump all over my
hopes...:-).

My original question stemmed from a wider perspective - I expect to have to
put a business + technical case for converting from MS-SQL to PostgresQL
soon. Do people with actual dirt on their hands point to a good source for
Postgres performance tuning?

I'm still digging postgresql.org and last time I went to a (large) book shop
I saw an entire section (about 6-7 shelves) about MySQL but not a single
book about PostgresQL.
