Background
I am setting up a new NAS system that will use TrueNAS. (The RAM is ECC incase that info is useful)It has the following hard drive setup - all drives have been bought brand new and are still under warranty.
I am trying to ensure the drives are healthy before beginning to use them.
OS Drive:
1x SSD M2.NVME drive (for the OS)
ZPool Drives (RAIDZ2):
4x Seagate IronWolf NAS drives - Model Number: ST20000NE000 20TB each
2x bought from vendor A
1x bought from vendor B
1x bought from vendor C
I am following the excellent guide by Uncle Fester and updated and hosted on danb35's Wiki:
https://www.familybrown.org/dokuwiki/doku.php?id=fester112:hvalid_hdd
After following the instructions on the 'Hardware Validation -> HDD/SSD Validation' section, below is what I have done so far.
Tests I have performed
Here are what tests I have run and in what order I ran them for each of the 4 seagate 20TB drives:SMART long test took around 24-26 hours for anyone interested.
1) Ran smartctl:
Code:
smartctl -t short /dev/ada{0..3}
smartctl -t convey /dev/ada{0..3}
smartctl -t long /dev/ada{0..3}
2) Running badblocks (Took well over 150 hours - Quite the coffee break!):
Then I ran the following badblocks on each of the 4 drives:
Code:
badblocks -b 32768 -c 512 -wsv /dev/ada{0..3}
3) Re-Ran smartctl again after badblocks completed without any errors:
Code:
smartctl -t short /dev/ada{0..3}
smartctl -t convey /dev/ada{0..3}
smartctl -t long /dev/ada{0..3}
Test Results:
badblocks test results:
All four drives successfully completed the 4 iterations of write/read without a single error.SMART test results - The Good:
To start with the good news, each of the four drives have good looking Self-test logs:Code:
SMART overall-health self-assessment test result: PASSED SMART Error Log Version: 1 No Errors Logged SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 269 - # 2 Conveyance offline Completed without error 00% 243 - # 3 Short offline Completed without error 00% 243 - # 4 Extended offline Completed without error 00% 28 - # 5 Conveyance offline Completed without error 00% 2 - # 6 Short offline Completed without error 00% 2 -
## SMART test results - The Bad:
According to the guide, the following attributes should all have zero values:Code:
Raw_Read_Error_Rate Reallocated_Sector_Ct Seek_Error_Rate Spin_Retry_Count Calibration_Retry_Count Reallocated_Event_Count Current_Pending_Sector Offline_Uncorrectable UDMA_CRC_Error_Count
As a side note, I noticed that the following 2 attributes are not present in any of the SMART results for my drives:
Code:
Calibration_Retry_Count = not present Reallocated_Event_Count = not present
However, in my results the following have non-zero values under the 'RAW_VALUE' column as shown below:
I am only including the attributes which failed to have zero results from the above list of attributes.
Code:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE ---- 1 Raw_Read_Error_Rate 0x000f 081 064 044 Pre-fail Always - 124361665 1 Raw_Read_Error_Rate 0x000f 083 064 044 Pre-fail Always - 217428929 1 Raw_Read_Error_Rate 0x000f 077 064 044 Pre-fail Always - 46461889 1 Raw_Read_Error_Rate 0x000f 082 064 044 Pre-fail Always - 141671361 ---- 7 Seek_Error_Rate 0x000f 080 060 045 Pre-fail Always - 106182699 7 Seek_Error_Rate 0x000f 080 060 045 Pre-fail Always - 106791513 7 Seek_Error_Rate 0x000f 080 060 045 Pre-fail Always - 106481643 7 Seek_Error_Rate 0x000f 080 060 045 Pre-fail Always - 106904772
My Question
As shown above, I am getting positive values in some of the results, whereas in the guide it says I should be getting '0' values.The guide also says:
"If you get any value other than zero in the “RAW VALUE” for these entries you should be suspicious of this drive and may need to return the device for testing depending on the manufacturer’s warranty"
The fact that badblocks ran successfully and that I sourced the 4 drives from 3 different vendors makes me feel it is unlikely that they all have similar faults and maybe the guide doesn't account for a possible change in hard drive SMART results/or technology?? I have no knowledge about how hard drives actually work so this is just an optimistic thought I had that would allow me to believe the hard drives are fine - HAHaha... (crying).
I would really appreciate any input about these results and whether the drives should be returned or I can begin to trust them and go ahead and start using them.
Thank you TrueNAS community!
