Creating RAID 1 using mdadm for Root disk in Linux:

I recently found one of our production server (running RHEL7) doesn’t have the root disk mirrored. So, we thought of using one of the spare disks (which has some junk data) for mirroring the root disk using mdraid.

I wanted to do it without disturbing anything on the server as it’s in production. I was checking how to do this with mdraid but couldn’t find anything that’s helpful.

Can someone please let me know how I can mirror the existing root disk with RAID 1 using mdraid?

Thanks in advance.
