Thanks for the reply. My RAID1 raid[1,2] devices are defined from 16 GiB 
partitions of the underlying HDD's, 2 each per raid device. They are not 
intended to be subdivided, AFAIK. Therefore, I'm guessing 
/dev/raid[1,2]a, right :-) ?

Another question, pertinent to this issue: is a RAID10 device such as I 
am trying to construct autoconfigurable during boot ? I am planning to 
use this RAID10 device as /usr, so it needs to be there during boot. The 
online man page says not, but it also says opposite things in different 
sections on other topics, so I am unsure about this. TIA & thanks again 
:-) ....
