Hey guys,

 

Long story short, one of my drives had a corrupted filesystem. I did not have a backup of the data and it wasn't that big of a deal because it was all replaceable. I formatted the drive and reinstalled. Everything was fine for a day or so, then I started having all sorts of random errors. To further aggravate things, in my carelessness I deleted my appdata folder (i did have a backup of this) and decided to use the opportunity to just reformat my cache drives since I was getting some csum errors from btrfs. Now I have a brand new cache pool and a brand new drive. The problem is the errors I am still getting and the server is locking up.

 

Here is a snippet of all the crap going on....

Any ideas???

Please post your diagnostics: Tools -> Diagnostics

Sorry, forgot about that. Here you go!

Since there's corruption on both cache devices, and according to you they were recently formatted, I'd start by running memtest for a few hours, then run a correcting scrub you the pool and make sure all errors are corrected.

 

For the locking up make sure you are disabling C-states, see the Ryzen notes:

 

I will give the memtest a try. I tried a scrub once already and it came back with 20 uncorrectable errors from what i remember. But I will try it again after a memtest. As for the cstates/zenstates thing, i definately have cstates disabled in the MB BIOS and when i tried the zenstates code it made the system very unstable so i havent been using it.

Wellllll, I think we found the problem.
