I am starting to see errors on my cache drive pool (sample attached) cachedriveerrors.txt

I suspect that one of the drives in the pool is starting to fail , but when i try to run smart tests on the drive nothing seems to happen (no feedback after the button click) 

 

The btrfs dev stats are not showing any errors:

root@TheBeast:~# btrfs dev stats /mnt/cache
[/dev/nvme0n1p1].write_io_errs    0
[/dev/nvme0n1p1].read_io_errs     0
[/dev/nvme0n1p1].flush_io_errs    0
[/dev/nvme0n1p1].corruption_errs  0

[/dev/nvme1n1p1].flush_io_errs    0
[/dev/nvme1n1p1].corruption_errs  0
[/dev/nvme1n1p1].generation_errs  0

 

I  also attached the smart log that the system does have Samsung_SSD_960_EVO_250GB_S3ESNX0J930294R-20190524-1033.txt

 

 

Can anyone recommend how to troubleshoot this? 

Those are checksum errors, most commonly caused by bad RAM or similar hardware problem, very unlikely to be a problem with the SSD.

 

 

Thanks for the tip.. that would be unfortunate since i already replaced this RAM once (almost exactly a year ago) .. but i guess i will be running a memtest again

Thanks for the pointer.
