SoftRAID 6.0.3 not mounting drive at startup
I'm not sure if this is a software issue or an enclosure issue, but my OWC ThunderBay 4-Drive RAID-5 does not mount when my Mac (2019 Retina iMac, Big Sur) starts up. If I power-cycle the drive, it will appear. Any idea what the problem is or how to fix it?
If you run SoftRAID, do the disks show up on the left column? that will tell you if it is enclosure, or Big Sur not loading the driver.
I just experienced the same problem. Yes, I did see the disks on the left column. This happened right after upgrading to MacOS 11.4.
Try this terminal command:
sudo kmutil load -p /Library/Extensions/SoftRAID.kext
The "up" key in terminal will show prior commands, so next time you want to manually load SoftRAID, just hit the up arrow and this command will be available without having to type it.
You may need to do this until Apple fixes this bug.
Is there any danger in upgrading to Softraid 6.0.5?
With some embarrassment, I have to confess that this may have been caused by a loosening power cable on the RAID. I noticed that after I accidentally bumped it (it sits in an adjacent room because of the noise). It has come up every time ever since then.
In my many years of working in technology, I still find that 90% of troubleshooting for myself or the people I support can be resolved in two basic steps:
- Is it turned on?
- If it's turned on, is it plugged in?
Thanks for your support!
Oft times you are correct. Modern technology also adds the "magic" component, where things should work, but don't. Where it used to be "stupidity is doing the same thing over, and expecting a different result", with technology, this is provably false! Success is sometimes stubbornly persisting, doing the same (supposedly correct) thing until it starts to work! ;-)
