How to add a raid 1 on a running Centos raid 0

[ShadowElf2]

hy all

could any help me to add a raid 1 on a running Centos raid 0

I have 2 disks 1 Tera in raid 0 (raid 1 for boot, raid 0 sistem)

I want to add another 2 Disks 1 Tera for stability

I did it raid 0 for speed, I realy need speed for disks, but now I want to be shure I don't lose data. I didn't find any perfect setup...

I use this configuration on an Centos 6 and Centos 5.6 (2 servers)


thx

my "df -h"
