Hello, Parted fail to notify linux kernel with correct partitions information with non-partitionable md devices. It is in fact partitionable when kernel version > 2.6.28.
The bug may be caused by `_device_get_partition_range()' in `linux.c'. It reads /sys/block/`mddev'/range to get partition range of the raid device. But in linux, device with extended partitions support also has a sys file named `ext_range'. The real range of extended-partition device should be `range + ext_range - 1' (FIXME ?). For md device, it has value '1' in /sys/block/md1/range, and value '256' in /sys/block/md1/ext_range, so it can support 256 partitions. `_device_get_partition_range()' will return '1' in this case, and parted then reports only 1 partitions to the kernel. If a device with '1' in 'range' file and non-extended-partition support, maybe `_device_get_partition_range()' should return 0 to indicate it doesn't support partitions? By the way, how to subscribe this mailing list?
