The driver is loading. The volume should be OK to mount. if it is not mounting, then the directory is damaged. The support file does not show clearly what is wrong.

Do you have access to Disk Warrior? It may be the best thing at this point. You can also try a restart. the clue that the driver is loading is in the expanded volume tile. Notice your volume has a disk identifier, disk8 in this case (this can change)

This is not the issue where the driver is blocked.

Let me know if I missed anything or if there are some other options.

Thanks.

I understand your frustration. We are both reporting this issue to Apple and researching this ourselves.

A user mentioned that the latest 11.5 beta fixed his issue, perhaps there is hope.

Its not good to run with a mismatched driver, however, so your force restart trick is unsafe. There is a built in driver (limited), but when drivers are not loading, neither is the bundled driver.

I am not sure when this is going to be fixed, but it becoming clear this is a issue with the permissions architecture in Big Sur. Hopefully we can find a clear way to make this simpler, but the issues are inconsistent. Users should not have to struggle with as basic a thing as an intentionally installed extension loading.

No go. Restarted into Recovery. Disabled SIP. Restarted. Issued the command in Terminal. Restarted. Re-installed SoftRAID driver. Restart. Drives did not mount, nor was I ever prompted to Allow the driver.

So I re-installed the driver again which immediately mounts the drives, then I force quit on the SoftRAID application to avoid the forced restart which will cause my drives not to mount.

Lets try the test which has helped two users:

Disable SIP

(startup in internet recovery mode (command r), and enter this in terminal:

csrutil disable.

restart and run this command in terminal (copy/paste)

sudo rm -r /var/db/SystemPolicyConfiguration/KextPolicy

restart and run SoftRAID. reinstall the driver. Does this work?

I am testing this theory.

Would you please help me as well? Every time I restart my SoftRAID volumes won't mount. I have to go though uninstalling, clearing kext, rebuilding boot cache, reinstalling, and then it works until I reboot again. But now Big Sur never asks me to "Allow" at any point during that process.
