New subject: Antwort: How can I create raid 1 - Centos 5.7 64 minimal installation

18 Nov 2011


      Hello,
I have a server working on centos 5.7-64 minimal installation. I have
3 separate physical drives:
120 gb ssd, 2x 3tb disks for storage.
My linux installation is on ssd disk, and I want to make raid 1 for
these two 3tb disks and store data, like under /mnt/data.
Can you please tell me the path how this is possible?
Thanks for your help!
Best regards,
Here are some output of commands I ran for more data:
