Hi All, I am trying to create an MD device. I am using the command: /sbin/mdadm --create --a /dev/md12 --level=1 --run --raid-devices=2 /dev/sda12 /dev/sdb12 to create the device, and to dynamically create the device file if needed. What I want is the device file to be created as /dev/md12, but with the -a flag it creates it as /dev/md<first unwsed minor number>.
I have tried various options to the -a or --auto, but cannot seem to find the correct syntax. From the man page it says: -a, --auto{=no,yes,md,mdp,part,p}{NN} Instruct mdadm to create the device file if needed, and to allocate an unused minor number. "yes" or "md" causes a non-partitionable array to be used. "mdp", "part" or "p" causes a partitionable array (2.6 and later) to be used. The argumentment can also come immediately after "-a". e.g. "-ap".
Am I doing something wrong, or is there no way to get mdadm to automatically create a specific device file.
Thanks...
