April 27, 20206 yr Hi, I can't get rid of SMART health check errors. First I had 6-drive in 5.25" slot which had poor-feeling Chinese SATA cables. I was sure the problem was with the slot or the poor cables. I ordered good quality (afaik) SATA cables and directly connected my 2 cache SSDs to the MB. I still keep getting those errors, but now only for "Cache 2" disk. I run them in btrfs RAID0 (for higher write speeds). It might not be relevant but I have Dynamix SSD TRIM scheduled to daily. Error code: 199 (UDMA CRC error rate) Drives: 2x Samsung 860 EVO 2TB Age of the drives: 5 months btrfs filesystem df: Data, RAID0: total=384.00GiB, used=131.38GiB System, RAID1: total=32.00MiB, used=48.00KiB Metadata, RAID1: total=2.00GiB, used=272.06MiB GlobalReserve, single: total=26.30MiB, used=0.00B btrfs balance status: No balance found on '/mnt/cache' Is this a known problem with btrfs RAID0 or with the drives? What should I try next? Is the risk of data corruption increased when this keeps happening?
