I set up an Xpenology system a while back with their SHR solution and BTRFS, with six mostly mismatched-sized drives into one volume. So one drive is a parity drive. Every now and then I get checksum mismatch errors, which sucks because I built this primarily to have a robust and semi-reliable backup solution in parallel with a cloud backup solution. I'm on the latest DSM with Jun's loader.
Googling has found no solutions - before I give up and plan my next move, any advice on things to look into? A few thoughts I have:
-check hdd for bad sectors / issues (any bootable tools you guys recommend?)
-check RAM for issues (Memtest86)
While typing this I also realized I have not done "data scrubbing" in 4 months - is this something that can repair files that have been identified as having checksum errors?
