I know that to take root permissions I can tape "sudo su" and get priviledges, but I have never run the linux raid application from consolle. How can I do this.
In particular I have two disks that belong to a raid array 1 (mirror) that lost his partition and I have to recover data (file and folders) from it. They are in ext2 fs. They are fisically detected by knoppix disk utility but of course not logically.
Now, Inside the disk utility I have also the software raid in which disks are detected and I can read:
----------------------------------------------------------
Array name:0
Home host:-
Array size: 1,4 GB/1,3 GiB/.......... bytes
Array Type: Mirrored (Raid 1)
Components: 2 components (1500 GB each)
State: Not running
---------------------------------------------------

Ok this is the situation. I would like to run this raid array to take files and folders.

So the question is:
If I need authorizzation and cannot run application using windows but only using consolle, I get root priviledges with sudo command, and then? Which command I should use to run RAID software? And what are the parameters of this/these commands?

Any hints are welcome, Thank you in advance
