I moved the power cable to plug into a surge protector and not the UPS. Still have the same problem. Every second I see new seek error rate messages, some drivers report more at a time than others but all 4 are doing it. # smartctl -a /dev/ada2 | egrep 'Error|ECC' Error logging capability: (0x01) Error logging supported. 1 Raw_Read_Error_Rate 0x000f 110 099 006 Pre-fail Always - 15160 7 Seek_Error_Rate 0x000f 078 060 030 Pre-fail Always - 67260695 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 191 G-Sense_Error_Rate 0x0032 100 100 000 Old_age Always - 0 195 Hardware_ECC_Recovered 0x001a 037 004 000 Old_age Always - 15160 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 SMART Error Log Version: 1 No Errors Logged # smartctl -a /dev/ada2 | egrep 'Error|ECC' Error logging capability: (0x01) Error logging supported. 1 Raw_Read_Error_Rate 0x000f 110 099 006 Pre-fail Always - 15160 7 Seek_Error_Rate 0x000f 078 060 030 Pre-fail Always - 67260696 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 191 G-Sense_Error_Rate 0x0032 100 100 000 Old_age Always - 0 195 Hardware_ECC_Recovered 0x001a 037 004 000 Old_age Always - 15160 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 SMART Error Log Version: 1 No Errors Logged # smartctl -a /dev/ada2 | egrep 'Error|ECC' Error logging capability: (0x01) Error logging supported. 1 Raw_Read_Error_Rate 0x000f 110 099 006 Pre-fail Always - 15160 7 Seek_Error_Rate 0x000f 078 060 030 Pre-fail Always - 67260697 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 191 G-Sense_Error_Rate 0x0032 100 100 000 Old_age Always - 0 195 Hardware_ECC_Recovered 0x001a 037 004 000 Old_age Always - 15160 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 I will be stunned if it's yet another bad power supply, but I will have to find another one somewhere and test this again. The drives are all still under warranty. On Sun, Mar 16, 2014 at 2:42 AM, cruxpot <cruxpot@gmail.com> wrote: > It's an active PFC PSU plugged into an UPS which is not. Maybe that is > the problem.
