Seems to me that it would make more sense to just create a single raid array, then partition the newly formed disk:
Use RAID5 (striped) on the three disks. Creating a new virtual disk. Now partition that virtual disk into 3 volumes as you see fit. You'll get more redundancy that way too.
Now if you have two disks and want three volumes, do a mirror set, then partition that one mirror set to 3 volumes. What you're doing is asking for trouble later.

Nov 13, 2017 The 2-TB barrier is the result of this 32-bit limitation. Because the maximum number that can be represented by using 32-bits is 4,294,967,295, this translates to 2.199 TB of capacity by using 512-byte sectors (approximately 2.2 TB). Therefore, a capacity beyond 2.2 TB is not addressable by using the MBR partitioning scheme. Creating 2TB or Larger Partition with PARTED To do this, we have to partition the drives using PARTED, regular fdisk can’t do it (it doesn’t know how to handle anything over 1.9 TB), and mark the drives as GPT. We then use MDADM to create the software raid mirror. For the example, the two new 3TB drives will be /dev/sdb and /dev/sdc. How to set up a RAID in macOS Sierra’s Disk Utility. This will erase any data that exists on the disks you want to use for the RAID. Back up that data if you want to save it.

Does this work with SATA I tried to partition a mirrored RAID and was unable.
The RAID option tab did not show up in Disk Utility.

Not quite.. RAID 5 isn't possible through software (apple's at least), nor is slicing an array. The OG post is the only way to end up with multiple partitions + RAID.
Shouldn't this be called creating RAID from partitioned disks? This may be functional but I think this could cause a problem if a drive ever fails as you would lose all of your volumes
How to root hack glowlight plus on macbook pro. You can get rid of them, but doing so wouldn’t be a great idea – you’ll only see them the first time you launch an app, if you leave the “remember this” tickbox ticked. It’s a good idea to be aware of which apps are asking for superuser rights.The factory.zip file you downloaded was posted by Dean Gibson, one of the folks I learned a great deal about clockwork from.
This feels like a bad idea. Can the user actuallly confirm that if a drive fails the OS successfully rebuilds the data AND the partitions?
Feb 18, 2015 I want to have raid 1 on a 4TB drive, thus having redundancy on 2TBs. Is this possible?

G-RAID can be connected to any Mac or Windows machine equipped with a USB 3.0, USB 2.0, FireWire 800 or FireWire 400 port. For maximum performance, we recommend connecting G-RAID.
Dec 14, 2018 Your 4TB hard drive shows as only 2GB or even less capacity in Windows 10/8/7! Take it easy. The system did not eat the storage space at all. Follow the recommended way on this page to recover the 4TB full capacity on the hard drive.
Or would you need to manually recreate the partitions prior having the RAID array repair a faulty drive.
Good idea - but it just feels like a bad one. At least I wouldn't be trying it out without thorough recovery testing.
