How to create exFAT or NTFS RAID 1 I am looking for a way to create a RAID 1 Volume from macOS Sierra with a format that will be readable from both Mac and Linux.

Using DiskUtility I can not seem to find a way to format the RAID in another other formats other than JHFS+. Even from the command line. Maybe I am wrong and just have not found how to do it. Please let me know if I have missed it.

Other things I have considered is spinning up a virtual machine and/or Docker container and just doing it from Linux this way. Because I know how I can do it from mdadm.

I have also looked around for some third party software that can do this, but most of the ones that I have found are more than I'm willing to pay, since I know I can do it inside of Linux for free.

Lastly, I am trying to use luks to encrypt the RAID after it is set up. I am not sure any answers would prevent this, but just thought I would mention it in case it impacts the answers.
I created a RAID set using two USB sticks with Disk Utility in macOS Sierra 10.12.6. While I was only presented with Mac OS Extended options during the setup, once the RAID set was created I could erase it and choose another format.



After formatting the volume as ExFAT, I was able to store data on the RAID set.

However, I can't say what standard of RAID is used creating these sets. If you intend to connect the RAID set to another OS other than macOS, your millage may vary.
