Re: udev and mdadm -- I'm lost

Just use --auto or --auto=yes and it should  take care of the device node 
creations. I have a /etc/mdadm.conf  so I just do:
mdadm -As --auto=yes and it brings everything up over  udev.

Although if you want to use the scan option with auto you  may want to 
use mdadm 1.12.0 or later as on some of the earlier version  the 
combination doesn't work.  

Thank you Dave for your suggestion. Before you wrote back, I went ahead and  
tried out: 
 
mdadm -Av -amd 1 --uuid=xxxxx /dev/sd*
 
and that seemed to work. Is that okay. Unfortunately, "man mdadm" doesn't  
explain in much detail what the "yes" and "no" options do, unless I missed  
something. But the "md" option seems to make mdadm behave like it used to under  
devfs -- right? Only rather than specifing a device with the syntax "/dev/mdXX" 
 you just use "XX" or "X". 
 
It's not complicated, but it would be good to just know I'm doing it right.
