Storage system verify or repair failed 69716

I need to update my OS from Mojave to Catalina, although the update is recommending to update to Monterey. However, I'm getting the error message Storage system verify or repair failed (-69716).


any advice? I'm guessing I never updated from Mojave when recommended to do so...probably because I got the same error message and never resolved.


Thanks.

MacBook Pro 15″, macOS 10.14

-69716 System verify Storage Repair failed…

on an iMac (late 2012) with a 1TB Fusion Drive.

anyway, long story short... needed to recreate the fusion drive from the recovery terminal (after Backup, of course). After recreation, installation worked fine. 

This is definitely a Fusion hardware issue. I think that the drive is bad and needs to be replaced.

Thanks for your response.


I got it to work! After mounting (unlocking) my startup drive, Macintosh HD, in recovery mode, I followed the instructions to erase the drive and then restore from my current time machine backup from an external drive with the Mojave OS.


After confirming my data was there, I attempted to update to Monterey and it was successful. Phew!


The whole process took about 4 hours. So patience was required...but it also paid off. Yay! Drive appears to be okay.

I would be concerned that the hard drive of your Fusion Drive setup may be failing. I would suggest running the Apple Diagnostics to see if any hardware issues are detected. Unfortunately the diagnostics don't detect all drive failures so if the diagnostics pass, I would run DriveDx to check the health of both drives. Within DriveDx, click on the physical drive in the left pane and select the "Save Report" icon on the right side to save the report as a text file. Repeat for the other physical drive. Then open the saved report and copy everything in the file, then paste the contents here using the "Additional Text" icon which looks like a piece of paper.

BDA Aqua - we have the same issue in upgrading from Mojave.


We are following the apple.com instructions to recreate our fusion drive from the recovery terminal, but are not prompted to type "Yes" (Step 4 under "Using Mojave or later" instructions) so can't seem to complete this process. Any suggestions on how to resolve this. We have literally spent days trying to upgrade from Mojave to Monterey - we have erased our hard disk, reinstalled from external time machine back up, tried to upgrade from Mojave to Catalina (also not working). Not sure how to move forward on this.


Any help you can offer would be MUCH appreciated.

We followed the instructions on this page.


How to fix a split Fusion Drive - Apple Support


Our drive wasn’t split but we tried it anyway, maybe that’s why we didn’t get prompted to type “yes” as per step 4 in the instructions.


We called Apple Support. They suggested upgrading the OS from the internet rather than download. Gave the same storage system fail error. Apple Support have said I need to take the iMac into a store as it’s likely a hardware issue. I’ll be doing this Friday but if you have anything else I can try, we will!
