So, in short - is my data on the array in any danger, or is this just a cosmetic issue? [I think the reason it happened is that during the install process, where the installer asks you to choose partitions, I removed *everything* from mfid1,2 & 3 as I knew zfs likes to deal with the raw disk. I don't want to have to blat the system again though, unless absolutely necessary]. -- John
