Yes, I know that. Unfortunately, I'm working on an extremely
insert-heavy application (over 100 million records per day). I would
really like ReiserFS (due to the large file size as well as for the
journaling). I don't see how RAID5 can meet my needs.

I find that my RAID5 array is just too slow for my DB application. I
have a large number of DB files on this array. I would like to
convert to RAID0, and I can back up my files, but I was wondering if
there is a way to convert without reformatting?
Dave
Try adding a "default" line to your lilo.conf and see if that fixes the
problem.
There is a bug with the lilo that ships with RH6.2 and this seems to
workaround it.

Hi all. I'm trying to patch 2.2.14 with the patch on Ingo's site,

Your analysis is correct--RAID protects against disk failure, not against
other failures (such as NT eating itself, or for that matter, people
accidentally deleting files); it is not a replacement for tape backup, it
complements tape backup.

2. Swap to a HARDWARE RAID array..

advantage of SCSI bus mastering, for example?

Sounds a lot like the "coda fs". replicated fs that supports
