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.

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 got it to work, with fusion drive. thank you so much
Thanks for sharing. This process worked for me. Now my piece is back online.
