6.0.5 Upgrade - RAID Won't Mount

When you reinstalled, did you get the prompt to "Allow" OWC in System Preferences/Security?

You can try "reinstall SoftRAID driver, then go there before restarting and see if it is an option. Big sur blocks drivers first, asks later (or never).

Uninstalled the driver, restarted, re-installed the driver, no security prompt, nothing to do in system Preferences and the RAID mounted automatically.

Restarted, RAID didn't mount.

Then load the driver manually, until we can figure out what Big Sur is doing.

Try this command in terminal, just paste it in:

sudo kmutil load -p /Library/Extensions/SoftRAID.kext

I have just had the same issue - upgrade from 6.0.4->6.0.5 and no array mount.

Removed all non OWC enclosures, leaving just Mac Mini 2018 and 1x OWC Thunderbay Flex 8 - unable to mount single array 7x R5 plus 1x SSD neither mount

Update:

OS is 11.3.1

It appears that on this upgrade to 6.0.5 the security did not fully update and even though I rechecked it, restarts would not help.  Arrays would not mount and safeguard was showing as disabled.

I uninstalled the driver, restarted, installed the driver, added the lic. key back in and the arrays have returned.

Thanks

@softraid-support I had the same issue. Executing the suggested terminal command worked. 

@ncsa

Did you "Allow" OWC as an identified developer? It must be done each update. Let me know.

@electroant64

It might be temporary. We are still investigating why and we reported this to Apple, it may be we can fix this, or we may need to wait for the next Big Sur update.

Thanks, the Security change did pop up and it was approved but this time must not have saved and as a result all the array's did not show...

I then followed this:

- Ran the uninstall of 6.0.5

- Powered down all external drives, OWC, USB & LaCie enclosures

- Restarted OS

- Reinstalled 6.0.5

- Confirmed Security

- Restarted OS

- Opened SR

- Reapplied Lic. key

- Powered up drives in stages - they all came back online

- Restarted OS - to check - all good

----

- Powered down drives

- Updated to BigSur madOS 11.14

- Powered up drives - all good

Cheers

Tried this procedure ncsa described above but the issue remains for me. No mounting after reboot.

@gvansteelant

Its a short term workaround for a big Sur issue. Hopefully it will be fixed by Apple soon.

Note:
The "up" key in terminal will show prior commands, so next time you need to manually load SoftRAID, just hit the up arrow in the terminal window, and this command will be available without having to type it.

I have a slightly different issue.  Whenever I install a point version of the OS 11.2->11.3 or 11.3->11.4 or 11.4->11.5 (or any of the leading up to betas, the OS forced reboot initially won’t mount the RAID arrays (softraid 6.0.5).  But, an additional reboot initiated by me restores the RAID arrays.  It happens on multiple machines.

This is a Big Sur bug that Apple should be fixing at some point. You are lucky however, for most who see this, the driver never auto loads at restart. the easy way to get around this is loading the driver via terminal.app by pasteing this in:

sudo kmutil load -p /Library/Extensions/SoftRAID.kext

Note:
The "up" key in terminal will show prior commands, so next time you need to manually load SoftRAID, just hit the up arrow in the terminal window, and this command will be available without having to type it.

I wasn't sure whether it was an Apple bug or a OWC bug.  I've reported it to both.
