Thanks - I partitioned them yesterday using fdisk, but sfdisk looks like the kind of thing i was looking for (just a faster way of doing it). I then used raidhotadd to sync them, and checked using dmesg & /proc/mdstat. I was just being lazy when i emailed the list, hoping for a quicker way of doing all that. You have to create the partitions before you can use raidhotadd. im surprised that there is nothing in raidtools that just lets you import a new disk instead of a failed one and automatically copy over all partitions and sync all the data, in one go. i know this would be a dangerous command but it'd be very useful. ah well. :) thanks for the help Justin & Arend!, ivo.
