joelrfernandes Posted March 1, 2018 Share Posted March 1, 2018 Hello all, So, I had this old parity disk that I recently replaced with a larger one, which left me with this old 4TB drive. I pre-cleared it and added it to the array yesterday. Today it looks like unRaid claims the drive to be faulty, although S.M.A.R.T. reports say otherwise. What am I missing? The "faulty" drive is disk9 Diagnostics logs attached. monster-diagnostics-20180301-0940.zip Link to comment
trurl Posted March 1, 2018 Share Posted March 1, 2018 It's not faulty, it's disabled. unRAID disables a disk when a write to it fails. The failed write means the disk contents are invalid, but since parity was updated the array is able to emulate the valid contents. So, the physical disk has invalid contents and is out-of-sync with parity. Check connections. You will have to rebuild the disk. https://lime-technology.com/wiki/Troubleshooting#What_do_I_do_if_I_get_a_red_X_next_to_a_hard_disk.3F Link to comment
JorgeB Posted March 1, 2018 Share Posted March 1, 2018 Most likely disabled because of a very bad SATA cable: ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 199 UDMA_CRC_Error_Count -OSRCK 200 164 000 - 7313 Replace the cable and rebuild. Also upgrade to v6.4.1 so you're warned about similar issues in the future. Link to comment
joelrfernandes Posted March 1, 2018 Author Share Posted March 1, 2018 Alright, so I now replaced the cable and unraid is rebuilding the drive. I still have that UDMA_CRC_Error_Count of 7313 on the S.M.A.R.T. report, and now unRaid does mention it is a faulty drive: Should I just acknowledge the error? Link to comment

joelrfernandes Posted March 1, 2018 Author Share Posted March 1, 2018 quick question: if I acknowledge the current error, if that value increases in the future, will I get another alert or will it be silenced? Link to comment

joelrfernandes Posted March 1, 2018 Author Share Posted March 1, 2018 "yes" I will get another alert? Link to comment
