August 22, 20223 yr I have a set of SAS drives attached to my newly built UNRAID server - all looks to be working fine, it's well used and weekly parity checks report no errors. However running a SMART check with UNRAID always comes back the message "Errors occurred - Check SMART report" - this happens on every one of my disks. These are all HGST 2.5" SAS drives, 10K RPM 6GB/s drives. Checking the SMART reports however there are no obvious errors - I can't see anything that jumps out to me from the report as an error - what is the problem here: smartctl 7.3 2022-02-28 r5338 [x86_64-linux-5.15.46-Unraid] (local build) Copyright (C) 2002-22, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: HGST Product: HUC10121CLAR1200 Revision: F840 Compliance: SPC-4 User Capacity: 1,200,243,695,616 bytes [1.20 TB] Logical block size: 512 bytes Rotation Rate: 10020 rpm Form Factor: 2.5 inches Logical Unit id: 0x5000cca072c0f454 Serial number: L0KE3NJJ Device type: disk Transport protocol: SAS (SPL-4) Local Time is: Mon Aug 22 11:15:06 2022 BST SMART support is: Available - device has SMART capability.

August 22, 20223 yr GUI doesn't currently support SMART tests for SAS devices, you can still run them manually.

I just found it states this in the documentation too, no support for SAS drives for SMART. https://wiki.unraid.net/Manual/Storage_Management#SMART_Monitoring
