Yes.  Thus must not make problems.

Do you have some idea why the raid arrays were not autodetected?

This is because cfdisk can not work with partition tables where the
order of the logical partitions on the disk does not follow the order of
their numbers.  This was exactly what partman created here because hda7
was on the disk before hda5 and hda6.

Why partman/parted numbers partitions in this way is another story.  In
general this is because parted tries not to change the partition numbers
if possible.  When you removed you partitions there was no choice but
latter when you created hda7 there was no need to renumber hda5 and hda6
as cfdisk would do.
