Dismissing a RAID1
I've a task in mind that sounds simple, but I'm not sure it would be possible to complete. I'm dismissing a server, on which I've all partitions (boot partition and others!) mirrored as RAID1 through mdadm.
My idea would be to "dismantle" the raid, keep one of the two disks as "backup copy" of the server (possibly bootable and mountable at the need) and... discard the second copy and the rest of the hardware.
But reading here and there I'm confused on how to do it and if it will work as expected.
Thank you in advance!
