Fiservedpi Posted January 18, 2020 Share Posted January 18, 2020 (edited) Is this a sign of something bad? Edited January 19, 2020 by Fiservedpi Quote Link to comment
JorgeB Posted January 18, 2020 Share Posted January 18, 2020 Any unclean shutdown since last check? A few sync errors are expected after an unclean shutdown. Quote Link to comment
Fiservedpi Posted January 18, 2020 Author Share Posted January 18, 2020 No, here's the smart report if I'm reading correctly all my hard drives are in prefail? All drives are less than 4 months old I did relocate the server 18 days ago tower-diagnostics-20200118-1143.zip Quote Link to comment

I would normally just keep an eye on the ones that Unraid monitors by default (as set under Settings->Disk Settings). You then get notifications (assuming notifications are enabled) when these change. The only exception might be if you have run a SMART extended test when you want to explicitly go in and see if it passed/failed independently of the SMART attributes. 1 Quote Link to comment
Fiservedpi Posted January 18, 2020 Author Share Posted January 18, 2020 Ok thanks which attributes are indicative of a failing drive Quote Link to comment
PeteAsking Posted January 18, 2020 Share Posted January 18, 2020 The seagate has a high seek error rate but I dont really understand how to interpret that, maybe someone else knows if thats normal or bad: Seek_Error_Rate POSR-- 085 060 045 - 352968323 Quote Link to comment
Fiservedpi Posted January 18, 2020 Author Share Posted January 18, 2020 (edited) Why can't they just write it in English lol "yo disk f#$@ed buy a new one" Plug-in idea? Haha Edited January 18, 2020 by Fiservedpi Quote Link to comment
itimpi Posted January 18, 2020 Share Posted January 18, 2020 3 minutes ago, Fiservedpi said: Ok thanks which attributes are indicative of a failing drive The ones that you want to monitor especially are the Reallocated Sectors and Pending Sectors. reallocated Sectors are not necessarily a problem as long as the number stays small and stable, but a large number or a continually increasing number are a bad sign. Pending Sectors can be intermittent, but they are always working as they indicate there are sectors that may not be read correctly if another drive fails and a rebuild is necessary. However they not infrequently get cleared when the sector is next written so again not necessarily fatal if they only happen occasionally. The CRC count is one to monitor as it indicates a connection problem (typically cabling) rather than a disk problem, but they can still cause a read or write to fail causing Unraid to disable the drive. CRC count never gets reset - it only increases so keeping it stable is what you aim for. 1 Quote Link to comment

Fiservedpi Posted January 19, 2020 Author Share Posted January 19, 2020 Just upgraded to 6.8.1 re-ran parity check found 0 errors so guess it was a false alarm thanks for the info everyone Quote Link to comment
