does md have to depend on the raidtab file?


Did you change the persistent_superbit in raidtab before creating the RAID? If not, it didn't get written to the RAID superblock stored inside the partitions
used for the RAID -- and that's where it must be for raid autodetect to work.
Autodetect doesn't use raidtab -- the only thing that uses raidtab are the
raidtools themselves.


You might want to consider using mdadm instead of raidtools.
