[Sticky] Running Big Sur (beta) on Intel Macs
The .kext file is there for SoftRaid but the Thunderblade does not mount as a single volume. Disk Utility sees the 4 .m2 drives separately but does not sense the 8TB Thunderblade as a mountable drive.
If you see the SoftRAID driver there, then it is available and your volume should mount.
Don't use Disk Utility. Your volume should mount with an ! in the disk icon. What you should do is connect it to a Catalina volume and make sure it still mounts there.
Good. It means the driver must not be installed in Big Sur. What version are you running? Beta 6?
If you run this in terminal, after connecting the disks, what is the output, if any:
sudo kextstat -b com.softraid.driver.SoftRAID
(You can copy/paste it in)
I realise this is a huge longshot, but, I just spent a small fortune (in AUD) getting SoftRaid 5 from OWC this morning for my about-to-arrive 4xNVMe drives. However, I'm using Big Sur beta, and SR5 clearly isn't meant to work. I know it's not supported yet and all, but, would be great to be able to try out a beta if/when it works. Not sure how one gets that. I suspect BigSur will be finalised pretty soon anyway, and it's probably about 1.5 weeks till my PCIe card arrives in Oz...hopefully I didn't just waste $300 on SR5 if I have to buy an upgrade for SR6.
