Can I create partition on OS disk in fedora coreos

Hi Team,

I am newbie to fedora coreos, just have two queries.

  1. Is it possible to create partition on OS disk in fedora coreos (like normal Linux) with ignition file? I tried it, but every time it fails with error inappropriate ioctl with device. If it is possible, please point me to some documentation link.
  2. Is it possible to write fedora coreos on two disk in raid 1 configuration. I have two disk on server can both be used for OS setup in raid 1 configuration

Thanks in advance, It would be great if somebody can point me in right direction.
