Teza Posted November 20, 2019 Share Posted November 20, 2019 (edited) After installing unraid (first time user) disk 2 had a bad file system and it's 4GB capacity was not counted in the array. Parity read/check had 968081081 errors after 1h 3m. After a reboot, I formatted disk 2 and it became part of the array, and the array capacity increased to 12 TB. Everything looked ok. Then I tried to run a new parity-check, which I canceled after 160276490 errors, and because disk 2 status is now "Device is disabled, contents emulated". Searched the forum and did a diagnostics test that gave me the following info on disk 2: Quote smartctl 7.0 2018-12-30 r4883 [x86_64-linux-4.19.56-Unraid] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org Short INQUIRY response, skip product id A mandatory SMART command failed: exiting.

trurl Posted November 20, 2019 Share Posted November 20, 2019 On mobile now so haven't looked at Diagnostics yet. Bad connections are much more common than bad disks. Check all connections, power and SATA, both ends, including any power splitters. Then post new Diagnostics. Quote Link to comment
JorgeB Posted November 20, 2019 Share Posted November 20, 2019 Don't use the onboard Marvell controller (4 grey ports), it's dropping disks, and they are known to do that, all 4 disks with errors are connected there. Quote Link to comment

What controller would be recommended for this setup? Quote Link to comment
JorgeB Posted November 20, 2019 Share Posted November 20, 2019 Depends on how many extra ports you need after using the 6 Intel ones, for 2 extra ports get an Asmedia based controller, for 8 ports get an LSI HBA. Quote Link to comment
Teza Posted November 20, 2019 Author Share Posted November 20, 2019 Intel ones is 3.0 Gb/s while the grey ones is 6.0 Gb/s. Not sure if that matters with the cache drive? Quote Link to comment
JorgeB Posted November 20, 2019 Share Posted November 20, 2019 You have 2 Intel SATA3 ports and 4 Intel SATA2 ports, connect any SSD to the SATA3 ports, for disks SATA2 is enough. 1 Quote Link to comment
JorgeB Posted November 20, 2019 Share Posted November 20, 2019 5 minutes ago, johnnie.black said: 4 Intel SATA2 ports Correction, 8 Intel SATA2 ports, so you can use up to 10 devices with any additional controller. Quote Link to comment
Teza Posted November 20, 2019 Author Share Posted November 20, 2019 Stop the array Set disk 2 to no device Start the array Stop the array Set disk 2 to... Start the array The disk will rebuild. Followed this to get the drive back into the array. Is it normal to use 6h 30m on this process with empty disks, or does it not matter how much that is stored, as all calculations must be redone anyway? What testing should i do before storing data onto the array, when rebuilt? Quote Link to comment

Possibly it will take longer than the current estimate shown. I usually estimate 2-3 hours per TB. Quote Link to comment
Teza Posted November 21, 2019 Author Share Posted November 21, 2019 It took 7 hours and 27 minutes. Transferred 220 GB to the array and did a parity-check with no reported errors. Thank you for fast help! Quote Link to comment
