April 27, 201214 yr My parity drive consistently has shown errors under drive status on the Main page: Model / Serial No. Temperature Size Free Reads Writes Errors parity Hitachi_HDS5C302_ML4220F31B9ZZR 31°C 1,953,514,552 - 470,722 476,230 587 But this same drive passes the SMART tests and shows no errors in MyMain. It frequently fixes errors when it does the parity check every month. Last month there were 3 errors fixed. Is this something to be alarmed about, could I have a bad drive here or am I misunderstanding something? All the other drives have 0 errors unlike the parity drive. Thanks
April 28, 201214 yr It frequently fixes errors when it does the parity check every month. Last month there were 3 errors fixed.Most people specify a non correcting check for the monthly run, then if it shows errors, find the problem and run a correcting check after the cause is known. Do you have a reason for running automatic correcting checks? The only automatic correcting check I can see a need for is the one built into the unraid logic after a dirty shutdown.
April 28, 201214 yr The automatic monthly parity check in unMenu does not correct. You need to take action when any errors present. Start a thread. The parity disk is not doing well. 5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 8 196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 9 197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always - 53 T he disk should be replaced with a pre-cleared spare. Let the array rebuild. Then pre-clear the drive that you removed. Post a new SMART report. You can try to rebuild parity on to the current drive and then post a new SMART report. Enter "initconfig" or click the "New Config" button in Version 5.
May 4, 201214 yr Author I replaced the parity disk with a pre-cleared spare and have RMA'd it since it completely sh*t the bed. Thank you for your help. ~dustin
