I can't get my head around this, maybe it depends on the RAID controller and its implementation of capacity expansion algorithems as well.
When expanding an existing RAID 5 set with one extra disk, what will happen if the extra disk or a disk in the current set fails during the expansion procedure?
Same for RAID 6?
Same when converting from RAID 5 to RAID 6.
