I've nearly finished a build of a new NAS box (decided to switch from a Coffee Lake Xeon E-2136 to a Coffee Lake-R E-2288G; running 8 Seagate Exos X16 drives), and was testing the drives with the sol.net test script. I had been testing over the course of about 10 days, and received 14 CRC errors (in both dmesg and SMART output, so I'm sure that they were real). I ordered new MiniSAS cables (the drives are connected to an LSI SAS 9211-8i HBA, and yes, running P20 IT firmware) and replaced the old ones, and have been testing for 3 days so far. In that period, it's received one more CRC error on a new run.
Would that be within acceptable margins? My existing NAS build has one CRC error in total over its current drives' entire operational lifetime, so hopefully this won't be a regular occurrence. The commands are reissued immediately and it seems to carry on fine, and I've verified no medium errors so far in testing.
