SMART Results help

[flyinfitz1]

replaced my old WD Red 4x3TB RaidZ2 array with Seagate Ironwold 4x6TB RaidZ2. Overall Ive been happy with the drives other than they run a little hotter. Can someone take a look at the SMART results? Im concerned about the seek error rate. Seems like all the drives have this high count. Im on FreeNAS-11.3-U3.2 with hardware specs in my signature. Thanks in advance for the help!

Seagate says this is because they use proprietary fields not visible to smartctl to track the actual read error rate, and any counts here in the industry standard line are bogus. https://www.seagate.com/support/kb/how-do-i-interpret-smart-diagnostic-utilities-results-203971en/

Thanks so much! Do you know how I would tell if a drive is failing without using smartctl?

You can also use a smartctl switch to convert the values: smartctl -a -v 1,raw48:54 /dev/daX

See this site for the explanation of how that -v works to change the attribute 1 as shown... you could also do it for other attributes like 7 and 195, I suppose.

is this a permanent fix?

It's not a "fix" as such, it just allows you to see the human-readable version of that value (which will always be stored in that difficult to read way by the on-disk SMART controller when it performs the tests) when you query the value... means you need to use the -v switch every time if you want to read the output properly.
