November 25, 20169 yr I had my disk 10 show a failure a week or so ago so I replaced it with a new WD 3Tb Red drive. But this failed during rebuild. It seemed to be detected intermittently even after I swapped cables etc so I put it down to a dead drive. So I replaced it with another new WD 3TB Red and this one has failed during rebuild also. Any ideas why? tower-syslog-20161125-1350.zip
November 25, 20169 yr Community Expert Tools - Diagnostics. Post complete diagnostics zip. Always post complete diagnostics zip for V6 instead of syslog. Often disk problems are not caused by a bad drive. If you had asked before we might have been able to tell you there was nothing wrong with the original drive.
November 25, 20169 yr Author Thanks for that, see attached. As for the original drive it is a ST31500 and frankly I am surprised it has lasted this long, all the others I bought have died. tower-diagnostics-20161125-1430.zip
November 25, 20169 yr Author Hi, Thanks for that. Can I ask where in the diagnostics are you seeing that?
November 25, 20169 yr Community Expert syslog Nov 25 00:36:46 Tower kernel: md: import disk10: (sdh) WDC_WD30EFRX-68EUZN0_WD-WCC4N7DRA2TC size: 2930266532 Nov 25 00:36:46 Tower kernel: md: import_slot: 10 replaced smart for that disk
November 25, 20169 yr Author No I meant where did you see that Disk 10 did not report? I have run the short SMART without a problem, I am running the long one now. I just wondered where you saw the error so I can look for it in future.
November 25, 20169 yr The SMART report for that disk, the file called "smart/WDC_WD30EFRX-68EUZN0_WD-WCC4N7DRA2TC-20161125-1430.txt" in your diagnostics zip, shows that it failed to respond. The failure could be due to the disk, the cable or the controller. It's easy to check and eliminate the cable. smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.4.23-unRAID] (local build) Copyright © 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: /1:0:0:0 Product: Compliance: SPC-5 User Capacity: 600,332,565,813,390,450 bytes [600 PB] Logical block size: 774843950 bytes scsiModePageOffset: response length too short, resp_len=47 offset=50 bd_len=46 scsiModePageOffset: response length too short, resp_len=47 offset=50 bd_len=46 >> Terminate command early due to bad response to IEC mode page A mandatory SMART command failed: exiting.
