MacOS Sequoia 15.4, SoftRAID 8.5
I have 4 WD 12TB drives in an OWC ThunderBay 4 Enclosure
Drives were formatted by Disk Utility as APFS
When I try to create a New volume from SoftRAID, I get an error that "no disks available which have been initialized for use with SoftRAID.
When I select any of these volumes in SoftRAID, the "Initialize" choice is grayed out in Disk menu (and I see no way to initialize the disk).
I then converted the drives to SoftRAID non-RAID volume's.
They were then recognized however, the largest RAID 5 volume using all 4 disks, was only 55.8MB
These drives used to be a 36TB RAID 5 who connected to my old Mac.
I'm lost as to what to do next.
Thanks in advance.

I just tried "Deleting" the 4 Volumes and now I was able to initialize them.
I was then able to create a 36TB RAID 5 APFS using those disks.
Keeping this post in case others encounter this

What you likely missed was you need to select the specific disk to initialize. All disks need to be in SoftRAID format to create a volume and since we support multiple volumes on disks, you need to delete any existing volumes to create a new maximum size volume.
