December 14, 20205 yr Community Expert Hi I wanted to check the age of some second hand disks which I have precleared ready to use. I noticed in the preclear report it lists a "TIMESTAMP" attribute... "MOUNTED": false, "RUNNING": true, "TIMESTAMP": 1607962338, "TEMP": "0", "NAME": "sdb", "PRECLEAR": true Can anyone confirm this is the powered on time from SMART and what units it shows... e.g. milliseconds, seconds, minuters etc? I ask what units as if this assumption is correct the above file (if units is seconds) shows its been running for 51 years! Thanks in advance. Edited December 14, 20205 yr by SliMat

I am preclearing some disks on an HP server which is only running a trial version of UnRAID before moving them to a production server... where can I get the SMART info from? I am not sure where I can get the SMART info from. I have been looking for a Linux tool which can ideally be used from a bootable USB key. The closest I have found is smartctl in Ubuntu.
December 14, 20205 yr Community Expert Click on the disk in the Unraid webUI and look at its Attributes section or download its SMART report under Self-Test
December 14, 20205 yr Author Community Expert Thanks again @trurl Exactly what I was looking for - I dont have the (expired) trial running on this server at the moment, so will check if SMART log is downloadable on there too.

Use smartctl -h to get a usage summary I think this is because the array is SAS disks, so smartctl needs the "- d scsi" flag set - but I dont know if (or how) this can be set in UnRAID.
December 14, 20205 yr Author Community Expert Thanks @Squid - hadnt spotted that at all... Do you know how to add SMART attribute 09, Power on hours? I wrongly thought I could add 9 as a custom attribute;
December 14, 20205 yr Those are the monitored attributes. You really don't want to add POH as a monitored attribute as you'll get a notification every hour.
December 14, 20205 yr Author Community Expert So on the downloaded SMART report it doesnt list POH... or am I missing something; smartctl 7.1 2019-12-30 r5022 [x86_64-linux-4.19.107-Unraid] (local build) Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: HP Product: MM0500FBFVQ Revision: HPD9 Compliance: SPC-3 User Capacity: 500,107,862,016 bytes [500 GB] Logical block size: 512 bytes Rotation Rate: 7200 rpm Form Factor: 2.5 inches Logical Unit id: 0x5000c50042209a87 Serial number: XXXXXXXXXXXXXXXXXXXXX Device type: disk Transport protocol: SAS (SPL-3) Local Time is: Mon Dec 14 23:17:16 2020 GMT SMART support is: Available - device has SMART capability.

I hadnt... when I first tried it, it just came up with an error - till I realised that disk 9 is actually disk index 8 as it goes from 0-15 on my 16 disk array 🙂 Once I put this right, it did download a SMART report... but still no POH 🤔 smartctl 7.1 2019-12-30 r5022 [x86_64-linux-4.19.107-Unraid] (local build) Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: HP Product: MM0500FBFVQ Revision: HPD9 Compliance: SPC-3 User Capacity: 500,107,862,016 bytes [500 GB] Logical block size: 512 bytes Rotation Rate: 7200 rpm Form Factor: 2.5 inches Logical Unit id: 0x5000c50042209a87 Serial number: XXXXXXXXXXXXXX Device type: disk Transport protocol: SAS (SPL-3) Local Time is: Mon Dec 14 23:37:19 2020 GMT SMART support is: Available - device has SMART capability.

December 14, 20205 yr Author Community Expert I thought I would try this on another server I have running SATA disks and the SMART report is much more detailed... there is a section which lists the POH properly... so it looks like this is something to do with the fact the disks are SAS ?!?!? Part or the SATA disks SMART report...

December 15, 20205 yr Author Community Expert OK, looks like I have got to the bottom of why POH is missing... my array has a number of different disks... I have some 2Tb Seagate disks - when I checked one of these I get a lot of SMART information including POH. I also have some 600Gb "HP" disks - these also show POH. However the 1Tb "HP" disks done show much SMART info... so it looks like the problem is that not all the disks report all the correct SMART data. I'm not sure if there is a way to enable SMART reporting on the disks which dont seem to support it... so, if anyone knows please do let me know. Thanks everyone whos helped 🙂

Slot0 is considered to be the parity slot in Unraid as you can see in the syslog.
December 15, 20205 yr Community Expert IIRC it's a problem with Smartmontools, it doesn't show all the info for some SAS devices, including temp, older (and possibly newer) releases should.

Thanks @JorgeB - in the mean time I will try to find another non-UnRAID based tool to check these details
