Based on reading the documentation, it looks like the KDE Partition Manager doesn't really deal in RAID, except maybe with Btrfs. If I were to create a RAID set with mdadm, I suppose at that point the KDE Partition Manager would detect the created software RAID drive and be able to manage its contents? I'm rusty with mdadm, but once dealt with it every day. Anything else to think about? TIA, --Bruce
