+Takeover/Reshape Support
+------------------------
+The target natively supports these two types of MDRAID conversions:
+
+o Takeover: Converts an array from one RAID level to another
+
+o Reshape: Changes the internal layout while maintaining the current RAID level
+
+Each operation is only valid under specific constraints imposed by the existing array's layout and configuration.
+
+
+Takeover:
+linear -> raid1 with N >= 2 mirrors
+raid0 -> raid4 (add dedicated parity device)
+raid0 -> raid5 (add dedicated parity device)
+raid0 -> raid10 with near layout and N >= 2 mirror groups (raid0 stripes have to become first member within mirror groups)
+raid1 -> linear
+raid1 -> raid5 with 2 mirrors
+raid4 -> raid5 w/ rotating parity
+raid5 with dedicated parity device -> raid4
+raid5 -> raid6 (with dedicated Q-syndrome)
+raid6 (with dedicated Q-syndrome) -> raid5
+raid10 with near layout and even number of disks -> raid0 (select any in-sync device from each mirror group)
+
+Reshape:
+linear: not possible
+raid0:  not possible
+raid1:  change number of mirrors
+raid4:  add and remove stripes (minimum 3), change stripesize
+raid5:  add and remove stripes (minimum 3, special case 2 for raid1 takeover), change rotating parity algorithms, change stripesize
+raid6:  add and remove stripes (minimum 4), change rotating syndrome algorithms, change stripesize
+raid10 near:   add stripes (minimum 4), change stripesize, no stripe removal possible, change to offset layout
+raid10 offset: add stripes, change stripesize, no stripe removal possible, change to near layout
+raid10 far:    not possible
