Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Not sure what the right thing to do here is, or even if it's a real problem, but: I have 8 75GB IBM drives striped in a big raid 0 for monkeying with. newfs -i 131072 -v /dev/vinum/bighonkindisk seems to very nicely put all the data that newfs write out on to the first disk... It least, only the first disk gets any io, accoring to systat and iostat. Which would seem to me to be problematic in terms of using fsck -b, and also just for the fact that it would seem that you would have to hit that disk more often than the others, even though it's striped. I realize there's no protection with the raid 0, but the load doesn't seem evenly distributed on a transaction basis, even though the data is evenly spread. What's the right thing to do here?
