if you want to mount a raid-1 member in a external system, you should install mdadm and checkout those commands:
# Connect harddisk to auto-plugable controller/system # Check which device name was assigned to the pluged-in harddisk tail /var/log/syslog fdisk -l /dev/sdb mkdir /mnt/data mdadm --examine /dev/sdb3 mdadm -A -R /dev/md0 /dev/sdb3 mount -o ro /dev/md0 /mnt/data # Read, what you want to read ;) umount /mnt/data mdadm -S /dev/md0 # Remove the harddisk
that is it. thnx [Milosz](%20 http://blog.sleeplessbeastie.eu/2012/05/08/how-to-mount-software-raid1-member-using-mdadm/) for your help and saving my time ;)
