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