Same question here. I've built LVM on MD on amd64 twice, once from the installer and once manually from the installer shell, no serious problems either time. Are you trying to run LVM and just back up one volume of it on a smaller disk? > > You should keep swap partitions off of MD devices.

It could just as easily not, of course, but I've used MD + LVM for small-scale production apps a few times and also am a bit paranoid =P. Anyhow, I've always preferred swap over RAID1/5 md wherever possible. - -- John Livingston -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
