rutherford Posted October 1, 2019 Share Posted October 1, 2019 Got a few read errors and have a disabled disk. Is it time to replace the drive? Thanks! rubble-diagnostics-20191001-0108.zip Quote Link to comment
rutherford Posted October 4, 2019 Author Share Posted October 4, 2019 (edited) https://wiki.unraid.net/Troubleshooting#What_if_I_get_an_error.3F I stopped the array, took my disk out of the array, and started it again. Now the data on the missing disk is being emulated. I'm performing a pre-clear on the disk in question again to see if anything pops up. Unless anything goes really wrong, I'll re-assign the disk back into the array, and unRaid will rebuild the data on that drive. If it goes south again, I'll order a new drive and replace it. SMART 5 - Reallocated_Sector_Count. SMART 187 - Reported_Uncorrectable_Errors. SMART 188 - Command_Timeout. SMART 197 - Current_Pending_Sector_Count. SMART 198 - Offline_Uncorrectable "SMART stat 187 reports the number of reads that could not be corrected using hardware error correction code (ECC). Drives with 0 uncorrectable errors hardly ever fail, Budman said, "but once SMART 187 goes above 0, we schedule the drive for replacement." https://www.computerworld.com/article/2846009/the-5-smart-stats-that-actually-predict-hard-drive-failure.html Edited October 4, 2019 by dkerlee Quote Link to comment
itimpi Posted October 4, 2019 Share Posted October 4, 2019 (edited) Just to check - can you see the data as expected on the emulated disk as rebuilding will give you exactly what the emulated disk shows. Some people assume it will magically recover files that are not being seen on the emulated disk but this is not the case. BTW: The diagnostics suggest that disk2 has dropped offline as there is no SMART information for it - is this the problematic disk? If so it might be worth posting new diagnostics after a reboot if you want any feedback on the SMART status of that drive. Edited October 4, 2019 by itimpi 1 Quote Link to comment
rutherford Posted October 21, 2019 Author Share Posted October 21, 2019 Ended up shutting down, wiggling the wires and double checking the connection. Seemed like that brought the drive back up. I re-added to array, it rebuilt, seems to be okay for now. Quote Link to comment
