Здравствуйте!
Из man mdadm:
--auto-detect
Request that the kernel starts any auto-detected arrays. This
can only work if md is compiled into the kernel — not if it is a module.
Arrays can be auto-detected by the kernel if all the components are in
primary MS-DOS partitions with partition type FD, and all use v0.90 metadata.
In-kernel autodetect is not recommended for new installations. Using mdadm
to detect and assemble arrays — possibly in an initrd — is substantially
more flexible and should be preferred.
То есть, Вы правы, ядро может автоопределять только части массивов,
находящиеся на дисках с таблицей разделов MS-DOS, на разделе с типом FD и
метаданными версии 0.90. Остальное автоматически не определится и в массив не
соберется.
Остается подождать, пока в make-initrd будет реализована поддержка mdadm (в
планах она есть) - тогда можно будет собирать при загрузке любые типы
массивов, поддерживаемые mdadm.
