good, I was hoping that would work... So if the drives get mismatched it can still piece them back together so long as all the same drives are back in the group? I would test the scenarios, but I already have LVM set up, so that would just be asking to lose data at this point. > To answer your question... > First, if any one of the drives failed you'd probably lose all your data > (so if I had those 3 drives, I'd have a 320Gb raid5 array and feel safe > that if I ever lost a disk then my data would be OK) > If you just moved a drive eg from one channel to another it'd be fine - > you'd never notice. is there a command I need to use to tell LVM that the drive moved? I remember adding them in I had to add the drives by name (/dev/hdX). I probably could do raid, but it's just TV recordings, if I lost them I wouldn't be TOO upset. I should set up raid on my other partitons, though, that's a good idea.
