Corrupt Leaf

[Fiala06]

This is the 2nd time I've had this issue and would love to know what causes it. I've attached my diag file.

 

Here is what I see in my log:

Any ideas what could be causing it?

That's metadata corruption, it could be caused for example by a flipped bit in RAM, you should run memtest, you also should avoid overclocked RAM, or better yet use a server with ECC RAM.

Thanks, I'll check but I don't think that is the case. I had this issue with my ryzen 2700x, ram and mobo which I used for a month before returning them Friday. Now it happened again with my i9, new mobo, and new ram running their stock speeds.

 

Do I need to format the cache drives again?

[JorgeB]

Ryzen is known to corrupt data with overclocked RAM, various users have found parity sync errors, but there could be other issues, best wasy forward is to backup cache, format and restore data.

Ahh, thanks! I guess it's possible this transferred over from the ryzen build.
