This may help if the problem is manly the log tree:

btrfs rescue zero-log /dev/sdg1

 

Pool was already detecting data corruption, you have RAM speed higher then it should be for your config, and that's a known issue with Ryzen, if the command above works you should correct that then run memtest and scrub the pool.

Thanks so much for a fast reply. I will give this ago I don't know why the RAM speed is higher as I have never messed with the ram

when i try to scrub i am getting an error csum2 so i done a filesystem scan and getting this error could you shed some light on what i need to do next ? thanks

That is not a scrub, does the pool mount after running the command above?

yes it does mount then went to do a scrub and could not complete it. it would just abort

In that case suggest backing up and re-creating the pool.

Hi all, 

I am having this issue today. Initially unraid sent a ton of messages indicating :
BTRFS warning (device sdg1): csum failed root (similar to this ) 
I tried o perfom a btrfss_scrub but it did not proceed . 
I rebooted the system and my Cache ssd (m.2) is now missing.

This is all the log i can get without being able of starting the array.

After array start please.

tower-diagnostics-20230626-1031.zip Hi , the option to start the array was greyed out. I hit the check mark on the option to start the array without the cache drive.

Sorry, I missed that the cache device was now missing, try power cycling the server (not just rebooting) or re-seating the device.

Ok, Power cycling brought back the SSD. 
Attached are the diagnostic files with the array back online. tower-diagnostics-20230626-1045.zip

Everything looks good so far, if it drops again save the diags before rebooting.

Understood , thank you for your time.
