December 18, 20187 yr Woke up to an error on my unraid this morning, Quote Event: Unraid Disk 5 error Subject: Alert [EPCOT] - Disk 5 in error state (disk dsbl) Some back ground information. I just replaced this drive a few weeks ago after receiving this error: Quote active 27 C (disk has read errors) [NOK] SMART Results ATA Error Count: 1 CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status register [HEX] Powered_Up_Time is measured from power on, and printed as DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes, SS=sec, and sss=millisec. It "wraps" after 49.710 days. Error 1 occurred at disk power-on lifetime: 9848 hours (410 days + 8 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 51 00 ff ff ff 0f Error: UNC at LBA = 0x0fffffff = 268435455 So I ran diagnostics (attached). And took down the array and rebooted. I was going to start the array but noticed is had Disk 5 as unassigned. I am suspecting a problem with that specific strand of the controller card. Not like I have extra of those sitting around. Looking for thoughts or other possibilities by people with more knowledge and experience than me. I posted another topic I may be relevant to this as it was Drive 5 that seemed to be constantly spinning: Thanks in advance and Happy Holidays everyone. epcot-diagnostics-20181218-0630.zip
December 18, 20187 yr Community Expert Disk dropped offline, so there's no SMART report, check connections and if the disk comes back online post new diags.

December 18, 20187 yr Author Came home, double checked all the cable connections brought it up and found the drive for me to assign disk 5 to. Ran short SMART report (attached) And latest diagnostics (attached). The drive is rebuilding. Projected time < 8 hours epcot-diagnostics-20181218-1532.zip epcot-smart-20181218-1521.zip
December 18, 20187 yr Community Expert Disk look fine, you should replace cables to rule them out if more issues in the future.
