dacmcbibs Posted May 24, 2019 Share Posted May 24, 2019 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/nvme0n1p1].generation_errs 0 [/dev/nvme1n1p1].write_io_errs 0 [/dev/nvme1n1p1].read_io_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?

JorgeB Posted May 24, 2019 Share Posted May 24, 2019 Those are checksum errors, most commonly caused by bad RAM or similar hardware problem, very unlikely to be a problem with the SSD. Quote Link to comment
dacmcbibs Posted May 24, 2019 Author Share Posted May 24, 2019 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. Quote Link to comment
