August 29, 20232 yr I am getting some confusing SMART results on my parity drive and I am guessing I just need to replace it. The SMART self-test shows: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 32282 - # 2 Short offline Completed without error 00% 18158 - But when I look at the SMART error log I see Error 676 occurred at disk power-on lifetime: 32556 hours (1356 days + 12 hours) When the command that caused the error occurred, the device was active or idle. After command completion occurred, registers were: ER ST SC SN CL CH DH -- -- -- -- -- -- -- 40 53 00 ff ff ff 0f Error: UNC at LBA = 0x0fffffff = 268435455 Commands leading to the command that caused the error were: CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name -- -- -- -- -- -- -- -- ---------------- -------------------- 60 00 90 ff ff ff 4f 00 15d+13:36:58.952 READ FPDMA QUEUED 60 00 30 ff ff ff 4f 00 15d+13:36:58.951 READ FPDMA QUEUED 60 00 40 ff ff ff 4f 00 15d+13:36:58.951 READ FPDMA QUEUED 60 00 40 ff ff ff 4f 00 15d+13:36:58.951 READ FPDMA QUEUED 60 00 40 ff ff ff 4f 00 15d+13:36:58.950 READ FPDMA QUEUED I have purchased a replacement drive but I don't have any open SATA ports. Can I just pull the current drive and put the new one in and have it rebuild the parity drive? Edited August 29, 20232 yr by jrhop added information
August 29, 20232 yr Author I do show on the dashboard that the parity status is: Parity Parity is valid Last check completed on Tuesday, 2023-08-15, 21:12 (fourteen days ago) Duration: 11 hours, 29 minutes, 24 seconds. Average speed: 193.4 MB/s Finding 0 errors Next check scheduled on Thursday, 2023-08-31, 23:30 Due in: 2 days, 12 hours, 10 minutes
August 29, 20232 yr Community Expert Last extended test passed, but it would be good to see the complete diags, if there were read errors.
August 29, 20232 yr Author @JorgeB Here is the SMART report for the parity drive and the complete system diagnostics. unraid-diagnostics-20230829-1714.zip unraid-smart-20230829-1713.zip
August 30, 20232 yr Community Expert The read errors are logged as a disk problem, run another extended test (or a parity check), if OK keep the disk for now, just keep monitoring, if not replace.
October 30, 20232 yr Author Is there a procedure to replace the parity drive when there are no open sata ports?
