I have an iMac 2020 model year and noticed that when running Disk Utility First Aid, it goes through just fine on the Main Volume Disk but the second partition of this disk (Data Volume), fails and says it cannot be repaired. The system itself seems to be working fine but just wondering if there's something I should be concerned about or how to resolve it. Here's the log:

Also, I tried running the repair after rebooting into Smart Recovery mode but same result. Any ideas/suggestions would be appreciated.

That was good thinking and what I was going to suggest. But I noticed this:

Have you tried that from Recovery mode?
