Ensure we recognize (and avoid) raid devices
nettings opened this issue · comments
I'm pretty sure the current heuristics would miss that the two first disks in this example (my dev box) are part of a raid, because the sdX1 partition has no mountpoint. Instead there is an additional raid device below, which doesn't share a common prefix with the disk device and thus wouldn't be noticed. So RAID users beware for now.
