juspifool Posted February 15, 2017 Share Posted February 15, 2017 (edited) I recently upgraded my server with a new motherboard, CPUs, and ram. Previous to that I upgraded to a 6TB parity drive. This morning I noticed that my parity drive was disabled so I stopped the array, removed it, started the array, stopped the array, added it back, and finally started the array to do a parity rebuild. That lasted a couple minutes then it was disabled again. Looking for suggestions on what to check next. OS: Unraid 6.3.1 Mobo: ASRock Rack EP2C602-4L/D16 CPU: 2x Xeon E5-2670s Partity Drive: WD Red Pro 6TB I've also attached the diagnostics file from the server. Thanks, Mark tower-diagnostics-20170215-1629.zip Edited February 25, 2017 by juspifool Quote Link to comment
JorgeB Posted February 15, 2017 Share Posted February 15, 2017 There's no SMART for the parity drive, but there's also no SMART reports for two other WD disks, so don't know if it dropped offline or if there's something wrong with the diags, try to manually get a SMART report for parity, reboot if the disk is offline.

juspifool Posted February 15, 2017 Author Share Posted February 15, 2017 Thanks for the check. I opened the case and disconnected/reconnected all the drives to be sure the cables were properly engaged. I can now see SMART reports for all WD drives and am currently running a parity rebuild. -Mark Quote Link to comment
juspifool Posted February 16, 2017 Author Share Posted February 16, 2017 It definitely made it further into the parity check this time but still failed. I'm going to replace the SATA cable for the drive but was hoping someone could take a look at the new diagnostics file and let me know if there is anything else I should check. -Mark tower-diagnostics-20170216-0704.zip Quote Link to comment
JorgeB Posted February 16, 2017 Share Posted February 16, 2017 Still no SMART report for parity and 2 other WD disks, if they work upload the manual SMART reports. Quote Link to comment
juspifool Posted February 16, 2017 Author Share Posted February 16, 2017 All 3 WD drives completed their SMART test without any issues. Attaching the reports. tower-smart-20170216-0752.zip tower-smart-20170216-0755.zip tower-smart-20170216-0758.zip Quote Link to comment
JorgeB Posted February 16, 2017 Share Posted February 16, 2017 One of those is from a Seagate, still missing parity. Quote Link to comment
juspifool Posted February 16, 2017 Author Share Posted February 16, 2017 Not sure how that happened. I am at 23% on my latest parity sync. Once that either finishes or fails I will upload the correct SMART report. -Mark Quote Link to comment
JorgeB Posted February 16, 2017 Share Posted February 16, 2017 Had some time to look at the logs more carefully and you're using the Asrock's 4 Marvell ports, your parity is there, that controller on those boards is notoriously troublesome, you'll want to move those disks to another controller, I'll bet you're troubles will be solved.

juspifool Posted February 25, 2017 Author Share Posted February 25, 2017 I ended up moving my parity drive off of the Marvell port. Everything went well after that. Thanks for the suggestion! Quote Link to comment
