March 10, 20179 yr I recently added 2 new drives to my array. One of the drives was connected to a Marvell 9250 controller and fell offline and caused the disk to be disabled. I took this chance to remove all the sata cables and reconnect/reposiiton them. Upon reboot, my parity disk was disabled. I shut down the server, reset the sata cable and powered back up. After checking the SMART report, I decided to unassign and reassign the parity disk. Partiy rebuilt and everything was fine. After about 3 days, the parity disk is disabled again and I can no longer check the smart report through the GUI (or through terminal). How can I check the SMART report of this drive? Following the wiki (http://lime-technology.com/wiki/index.php/Console#Console_Commands_for_Hard_Drives), results in the following error: Quote root@Tower:~# smartctl -a -T permissive /dev/sdb smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.9.10-unRAID] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org Short INQUIRY response, skip product id === START OF READ SMART DATA SECTION === SMART Health Status: OK Current Drive Temperature: 0 C Drive Trip Temperature: 0 C Read defect list: asked for grown list but didn't get it Error Counter logging not supported Device does not support Self Test logging tower-diagnostics-20170310-1423.zip

March 10, 20179 yr Author Here is the smart report after rebooting.

March 10, 20179 yr Community Expert SMART looks good, disk is already on the best possible controller (onboard intel), before rebuilding I would replace both cables or swap cables with another disk on the same controller just to rule them out.
March 15, 20179 yr Author Ok. I have tried to swap the sata cable and power connector twice. I have also swapped out the additional sata card as this issue started when I added 2 new drives to the array. tower-diagnostics-20170315-1134.zip tower-diagnostics-20170315-0939.zip tower-smart-20170315-1156 (1).zip
