I was afraid of that ;-) So, is that a correct way to automatically generate a correct mdadm.conf ? I did it after some digging in man pages: echo 'DEVICE partitions' > mdadm.conf mdadm --examine --scan --config=mdadm.conf >> ./mdadm.conf Now, when I do 'cat mdadm.conf' i get: DEVICE partitions ARRAY /dev/md/0 level=raid1 metadata=1 num-devices=3 UUID=75b0f87879:539d6cee:f22092f4:7a6e6f name='backup':0 ARRAY /dev/md/2 level=raid1 metadata=1 num-devices=3 UUID=4fd340a6c4:db01d6f7:1e03da2d:bdd574 name=backup:2 ARRAY /dev/md/1 level=raid5 metadata=1 num-devices=3 UUID=22f22c3599:613d5231:d407a655:bdeb84 name=backup:1 Looks quite reasonable. Should I append it to /etc/mdadm/mdadm.conf ? This file currently contains: (commented lines are left out) DEVICE partitions CREATE owner=root group=disk mode=0660 auto=yes HOMEHOST <system> MAILADDR root This is the default content of /etc/mdadm/mdadm.conf on fresh debian etch install. best regards -- Janek Kozicki - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
