I'm trying to script the RAID setup for a (growing) number of identical servers.  The advice I've seen for using mdadm suggests that once the RAID array has been created you can run mdadm --examine --scan >> /etc/mdadm.conf so that the array is initialised on bootup.  But that doesn't seem to work for me - in particular the array is presented as /dev/md/<hostname>:pool, where the mdadm --examine outputs /dev/md/pool.  Am I doing something wrong?  Is there something odd about my version of mdadm?[root@positron /]# mdadm --create /dev/md0 --level=0 --name=pool --raid-devices=6 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf[root@positron /]# mdadm --examine --scanARRAY /dev/md/pool metadata=1.2 UUID=567da122:fb8e445e:55b853e0:81bd0a3e name=positron:pool[root@positron /]# ls /dev/md/*/dev/md/md-device-map  /dev/md/positron:pool[root@positron /]# cat /dev/md/md-device-mapmd127 1.2 22a17d56:5e448efb:e053b855:3e0abd81 /dev/md/positron:pool[root@positron /]# mdadm --versionmdadm - v3.1.3 - 6th August 2010
