The day before I updated my home data graveyard from 10.1 to 10.3. This system had 10 disks before and 12 now. After update everything seemed reasonably ok except one strange problem:
SATA disk sdg - which has been in the system for about 2 years now - is properly detected but the single primary partition on it is not linked to /dev/sdg1. The device file is simply missing.
Seems it has been an old RAID superblock behind the active partition. I shrinked the raid where sdg1 is in by some cylinders to integrate a smaller disk some month before. So at the end of sdg has been an old superblock left. When assembling the RAID where sdg1 is in, mdadm found this old superblock at the end of sdg. When detecting this mdadm seemed to remove the device node for sdg1. There has been no message about it. It just told me there is no /dev/sdg1 - what has been correct as it had been disabled a microsecond before by the very same program ...
Anyway after cleaning up behind sdg1 it gets not anymore disabled and the real RAID can be created without problems now.
The partprobe problem simply has been a usage problem by me ...

Ralf
