In the example I've reported, each time I reboot I get just a single device, but its name changes. As stated in last e-mail: 1st boot: /dev/mapper/ddf1_4c53492020202020808627c300000000346e1b3c00000a28 2nd boot: /dev/mapper/ddf1_4c53492020202020808627c300000000346e1f3100000a28 3rd boot: /dev/mapper/ddf1_4c53492020202020808627c300000000346e1ff400000a28 I've sent you the image on the last boot (3rd), so you're having device name ddf1_...e1ff400000a28. So the problem is that device name get changing each reboot, while I don't have any other RAID chain in the system.
