[Sticky] SoftRAID driver not loading at startup in Big Sur - workaround in SoftRAID 6.1 beta

Problem:
Your volume does not mount at startup. Your volume appears in SoftRAID but does not mount.

When you attempt to mount it manually, it tries but never mounts. If you expand the volume tile for the volume, you will notice there is not a "Disk Identifier", such as disk8, instead, a - is displayed.

Cause:
There is a bug in Big Sur, where drivers designated as "auto-loading" is not loaded at startup. This affects multiple drivers, including the SoftRAID driver.

Solution:
SoftRAID 6.1 beta 7 adds a preference to work around this.

If you are running Big Sur (only, this is not available for Monterey, as we anticipate a fix from Apple before Monterey is released), if you go to "Application" preferences, there is an option to "Manually load SoftRAID driver on restart".

Select this option and restart.

SoftRAID will run a script at the restart to manually load the SoftRAID driver.

We would like feedback if this is indeed working as anticipated.

thanks!

Still running into issues. I'm on Big Sur 11.4, mid-2018 MBP i7 2.6ghz Vega 20 32GB RAM. After following instructions and restart, my 4M2 mounted-- but upon a subsequent restart it no longer mounts. It seems to only way to remount is to spam the script below in terminal until the drive mounts.

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

Have you tried 6.1 b7, and set the preference to manually load the driver? It should work.

Yes, I've done all of the above. It worked after 1 restart. Then after a second restart, it wouldn't mount and I had to use the command line. 

 

I just restarted a third time and the drive did in fact mount on its own. Seems to be working now for whatever reason. Big Sur has just been a Big Headache. I suppose if it refuses to mount in the future, I'll just run the command line. Thanks.

Its possible that Big Sur is not being consistent. We saw this in testing, which is why we are looking for user feedback. thanks!

 

Hopefully we will get a 100% solution, or alternatively, Apple will fix this.

Attach a SoftRAID Tech support file. You could have a different issue.

I think you tried, but did not attach a SoftRAID tech support file. Can you try again.

If you paste this into terminal, does your volume mount?

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

 

If so, check the disk preference in SoftRAID to manually load the driver in Big Sur. Next restart, your volume should mount.

 Just run the release version and install the driver is probably all you will need to do.

I had this problem, and chose to move back to 11.4 after...some frustration.

Reason for posting:

Just downloaded and installed 11.6. The SoftRaid volumes all just mounted, with SoftRaid 6.0.5

Perhaps Apple fixed it?

I do not know yet, we received no notice about this. But it would be great news!

I guess y'all finally recognized it as an important piece of duct tape until Apple never gets around to actually fixing itself ;)

 

I ran check for updates but it isn't finding 6.1?

We are still in beta with 6.1.

It was not trivial to add this, as there are cases where this does not work. Some kind of timing issue. But we have it in.

Apple still has not fixed this. In the meantime, I have dicovered this can affect Parallels, Roxio and other drivers.

@softraid-support yeah well nothing in sw dev is ever as easy as it should be eh?  always timing and race conditions when dealing with os shell scripts but eventually you learn how to handle them correctly.  parallels was causing all kind of issues for me running my vm from external raid.  it seems to corrupt the vm if the vm is not paused or stopped and the computer goes to sleep.  major pain in the ass to recover from. sometimes you get lucky and it will restart after wake from sleep and sometimes the vm is just totally jacked and you better hope you had a backup.

You will be at least happy to know that in our testing, we could find no ill effects from reloading the driver after startup, so with Big Sur, we will just do this automatically. No need for a preference file.

Now if we can just figure out how to stop the disk reordering, or find a solution that works without overly complicating or affecting performance of the SoftRAID driver.....
