I started the UBUNTU 10.04 LTS from CD. I was able to see the drives. I could connect to the new MBWE but I could not use the commands below which I had from http://en.wikipedia.org/wiki/Western_Digital_My_Book .
I always got error messages. Why? I don't know.
$ sudo modprobe md
$ sudo mknod /dev/md4 b 9 4
$ sudo apt-get install mdadm
$ sudo mdadm —assemble /dev/md4 /dev/sdb4
$ sudo mkdir /media/xyz
$ sudo mount /dev/md4 /media/xyz
$ sudo chmod -R 777 /media/xyz
Then I installed the UBUNTU on an old 160GB drive. From there I was able to get the array mounted.
But: The commands are different than in the script above, Luckily you get information on how this command should look like in the system itself or in the Internet.
$ sudo modprobe md -> this does not work at all.
$ sudo mknod /dev/md4 b 9 4 -> same but I had to enter something with …apt-get…. before. but that was shown as info.
$ sudo apt-get install mdadm -> different but you get information from the system. Then it installs also POSTFIX which was difficult to understand what to do now.
$ sudo mdadm —assemble /dev/md4 /dev/sdb4 -> here it said that I had to connect both drives from the raid
$ sudo mkdir /media/xyz -> same
$ sudo mount /dev/md4 /media/xyz -> same
$ sudo chmod -R 777 /media/xyz -> same
After that I could access the old raid array in UBUNTU and copy it to the new/old MBWE blue rings.
Maybe there are some LINUX specialist here who could update this script so that it can be used in UBUNTU V10.
Something I have to add. Before I could use the 160GB drive I had to copy about 50GB from this system to another system in my LAN. This was done with about 60 MB/sec. Now since the old RAID is up again I copy the old data (830 GB total) to the new MBWE in the same LAN. This is done at a speed of 3,5 MB/sec.
Maybe it would make sense to discuss which way is the best and most secure to store your data. (in my case pictures). when I was buying the MBWE I thought with two drives in a raid array this is the most secure. If a drive fails you just replace it and that's it. That it is such a problem to get to your data if the box fails I never thought.
I am not sure but maybe there is a wiki which discusses these issues but my question would be what way is the most convenient and most secure to store your data over years.
I would like to thank all the members (and especially the host and the admins) of this forum to take their time to run such a forum.
Best regards, Erich
