I suggest you try to boot with hda2 not in the array at all. Just hdb2. Probably this means usinf fdisk to tell hda2 that it isn't a raid device so it doesn't get auto-detected. Then When you have a raid1 array working off just hdb2, hot add hda2. Then set the partition type back, and reboot. > > Why does it show "Raid Level : multipath" ??? Weird. No idea. But it is getting it from hda2 which is why I say start the array without that. > > What are "Raid Devices"? The ones defined in /etc/raidtab? Yes, the number of devices in a fully working array. > Why "Total Devices : 1"? Is this the same as "Working Devices"? No. It includes spares. hdb2 thinks there is only 1 device of any sort at the moment. > Could devices be working but not active? Yes. A hot spare is working but not active.
