[Sticky] Big Sur on M1 machines and SoftRAID issues
Try in teriminal:
rm -r /Library/Extensions/arcMSR.kext
sudo kmutil clear-staging
sudo kextcache -i /
And click your startup volume, and reinstall the softRAID driver. See if that works.
Finally got it working.
When I did the terminal command to remove the two kext files in the systems library extensions folder ArcMSR and Promise??? I got a message that they could not be found.
I ran the two sudo commands you listed and reinstalled Softraid. This time I got the message asking me to allow the installation and went through that approval process.
Softraid completed installing and got the restart request.
Following restart I looked at the extensions list in About this Mac. It showed that the Softraid driver was installed. Although both the other extensions were still in the list although not installed.
Softraid started and I was able to initialized the drives and create three volumes.
So, it's functioning as it should.
Thanks for your help.
I included a report for your reference.
I had already written on the forum and I come back because I have a problem.
As a reminder, I have a MacMini M1 with a ThunderBay4 and 4 hard drives of 6 TB each. I made a certification of the disks which lasted several days, then I selected my 4 hard drives that I initialized in SOFTRAID (beta version), then I created a new volume in HFS + with the default parameters , everything is going well and I have the RAID5 volume which appears in the right column but it is not mounted and refuses to mount when I force it ... Suddenly the RAID does not appear on my desktop.
Is this normal?
When creating the volume, SOFTRAID informed me that it could not create a file system on the volume. Then it shows me everything as if it was okay (except that the disk is not mounted).
The SoftRAID driver is not loading, I suspect.
Did you "Allow" OWC as an identified developer in System Preferences/Security?
If you paste this commend into the terminal.app, does it show nothing? or show 6.0 b48 is loading?
sudo kextstat -b com.softraid.driver.SoftRAID
Running 6.0.1 b48 on M1 Air with ThunderBay 4 RAID with 4 WD 6TB Red+ drives.
Certification and initialization went without problems (kind of).
Created RAID 5 and start copying data with CCC app. Everything was fine for ~ 70% of 900GB data then Air went into Kernel panic and debuted. Rebut was slow and after rebut computer was sluggish. In SoftRaid volume was marked as Unmounted, but visible in Finder.
I tried to mount it and got second panic. Disconnected ThunderBay during rebut and Air buts up fast as usual and was responsive as usual. Connected back ThunderBay and without mounting volume in SR restart cloning. While I was typing this message got 3rd panic.
ThunderBay is disconnected now since I would say it's unusable as it is and it doesn't make me happy since I need it and ~$1K investment is unusable.
I don't know how to attach panic report since either ZIP to TXT not allowed. I can copy paste all 3 of them, but it will be quite long.
I would really appreciate any suggestion how to resolve it and make it usable.
I added txt and .panic support to the forum. So attach a support file and you can add the panic logs.
I do not know what is wrong, I have not seen this behavior. It may be a hardware issue, maybe the support file will help.
Clarification: ThunderBay 4 is new which I received from OWC earlier this week.
