September 15, 20187 yr Evening, Following on from another post, I switched out the 410 raid controller on my HP DL380G8 to an LSI 9207-8i, in the hope I would have more control of the drives, and no longer need to do the 'Raid0' thing for each drive. Long story short, I eventually rebuilt the system in the end as the drives were coming up as unknown (no big issue to restore everything). However, whilst hoping I would then have access to the SMART data, I find that Unraid is unable to read the capabilities of the SAS drives, but the SATA drives are fine. Each time I try running the SMART tests I get an error, or the system says the drive needs to be spun up (I think they are all spinning anyway, as I thought it wasn't possible for unraid to spin down a SAS drive? Was it a wasted upgrade? thx
September 15, 20187 yr Does the SMART data show up? If yes and for SMART tests you can always run them manually and make a feature request for the GUI to be corrected for SAS drives.
September 16, 20187 yr There is already support for SAS devices built-in. As @johnnie.black says, check manually (CLI) if smart attributes can be read and post the result here.
September 19, 20187 yr Author This is what I get using the 'smartctl -a' against one of the hard drives: It does look like SMART data is available, but whenever you run the test in the gui, it flags up errors (is it referring to the ones in the 'counter log' bit maybe)? thx ---------------------- smartctl 6.6 2017-11-05 r4594 [x86_64-linux-4.14.49-unRAID] (local build) Copyright (C) 2002-17, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: HP Product: EG0900FBVFQ Revision: HPDE User Capacity: 900,185,481,216 bytes [900 GB] Logical block size: 512 bytes Rotation Rate: 10020 rpm Form Factor: 2.5 inches Logical Unit id: 0x5000cca02211f1e0 Serial number: KPV9VY4F Device type: disk Transport protocol: SAS (SPL-3) Local Time is: Wed Sep 19 09:21:49 2018 BST SMART support is: Available - device has SMART capability.

September 19, 20187 yr Author Yup, it does. If I run it in the GUI it starts the test and then throws back the 'error' message, but if I check the progress in the CLI it shows it still running: ----------------- Self-test execution status: 52% of test remaining SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background short Self test in progress ... 6 NOW - [- - -] # 2 Background short Completed - 24740 - [- - -] # 3 Background short Completed - 24655 - [- - -] ------------------ and then eventually completed: ------------------ Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background short Completed - 24748 - [- - -] # 2 Background short Completed - 24740 - [- - -] # 3 Background short Completed - 24655 - [- - -] ------------------- There is a bit that says 'non-medium error count' and this goes up by one each time what ever that means! Edited September 19, 20187 yr by Ducky wrong data
