As requested, I'm filing a request for Linux software RAID support in KDE Partition Manager. This should also include all capabilities, present and future, of mdadm.

Thank you for your work so far on this app that yields such great potential!

Some of the things we need to test once it works better:

 * It should be possible to remove inactive RAID member partitions.
 * Somehow handle the case when recreating partition table when there are active RAID member partitions. Does the same problem happen with LVM PVs?

This already works, but we'll have to implement stopping RAID device from GUI.

 * GUI: when creating partitions inside RAID, we shouldn't show LV name field (which is specific to LVM)

I just checked how this works on LVM. LVM PVs that are part of LVM VGs are set to be "mounted". This is enough to let KPM know that it can't delete partition table of that device. So in the future, we can also mark raid_members as mounted.
