In-Reply-To: <20010102230107.A559@basildon.homerun> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've been using vinum to mirror some 20gb UDMA66 IDE drives for about 8 months now. I've even had a drive failure in that time (my 2nd western digital 20gb drive to die within a year -- I bought a Seagate this time!) When I bought my seagate drive as a replacement, the size of the drive was slightly smaller, and I had to figure out how to reduce the size of the plex without losing the data. (making the new drive a standard UFS drive, copy the data to it, delete/create the old drive with a smaller plex, copy the data back, make the plex on the new drive, and make the drives sync up) I have to say: 1) vinum is a life saver. 2) once you're able to keep all the terminology straight in your head, vinum is a very powerful tool. 3) vinum has been very stable for me. (no failures) 4) it has greatly increased read performance when the system is under load I don't know if my input is helpful, since I'm not doing striping at all, but I thought I'd give my 2 cents. :) On Tue, 2 Jan 2001, Thomas Seck wrote: > Hi all, > > sorry if this is OT for -stable, but I followed the discussion about > vinum in here and got a bit worried. > > I am currently deploying a proxy server for our company.
