https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194522 Bug ID: 194522 Summary: smartmontools misbehaving Product: Base System Version: 9.2-STABLE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: jdc@koitsu.org Created attachment 148554 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=148554&action=edit dmesg.txt NOTE: FreeBSD version involved is technically 9.3-STABLE, but the Bugzilla GUI only offers up to 9.3-RELEASE. Rephrased: I run base/stable/9. I'm filing this PR in combination or relation to an open ticket I filed with the smartmontools folks: http://www.smartmontools.org/ticket/466 Full details, including all output and lots of examples, are there. Basically, there is something going on within FreeBSD (or possibly within smartmontools, although rebuilding smartmontools 6.2 and using that shows the same problems) where certain SMART attribute values do not seem to appear/behave correctly when compared to values in the SMART extended self-test log. The issue is 100% reproducible, and cannot be reproduced on Windows. Specifically, a self-test issued at a certain Power_On_Hours count does not appear that way -- e.g. if Power_On_Hours is 12345 and a self-test is run, the SMART extensive self-test log might show the test completed at time 12189, or possibly sometime in the future. This issue affects multiple models of MHDDs and SSDs, and makes data recovery and diagnostics extremely difficult given the behaviour. The ATA CDBs being submit to the drive + full response payload I can try to get using CAM debugging, but I at least wanted to file a PR on the matter because at this point it's looking to be FreeBSD-centric in some way. I'll attach dmesg output, as well as pciconf -lvbc output. -- You are receiving this mail because: You are the assignee for the bug.
