Perhaps a duplicate UUID or label.
I doubt it. The Seagate 1 TB HD is independent from the system disks which contain the raid arrays.
I experimented a little bit. Replaced the 1 TB Seagate with a 320 GB Western Digital WD3200AVVS drive. In this case the arrays were assembled correctly at boot. The I replaced the WD drive with another 1 TB Seagate (ST1000DM003, same model but different device). With this other Seagate the arrays are not assembled. So it seems that problem it triggered by some device specific property.
It does look as if some identifier is duplicated. Check them all. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
