Helmonder Posted April 1, 2012 Share Posted April 1, 2012 I ran preclear twice on the same WD20EARS disk. The first time I got this in the summary: Changed attributes in files: /tmp/smart_start_hda /tmp/smart_finish_hda ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VALUE Temperature_Celsius = 115 114 0 ok 37 Reallocated_Event_Count = 198 199 0 ok 2 No SMART attributes are FAILING_NOW 1 sector was pending re-allocation before the start of the preclear. 1 sector was pending re-allocation after pre-read in cycle 1 of 1. 1 sector was pending re-allocation after zero of disk in cycle 1 of 1. 1 sector is pending re-allocation at the end of the preclear, the number of sectors pending re-allocation did not change. 4 sectors had been re-allocated before the start of the preclear. 4 sectors are re-allocated at the end of the preclear, the number of sectors re-allocated did not change. Can I trust this disk in the array? Thank you I am tempted to say no... I have spent some time browsing the forums on SMART results, what I have come to understand is that what your drive is doing could possibly be ok, but parts of the drive ARE failing so it comes down to wanting to take a risk... Looking at the prices of disks I would advise taking out this disk, using it for some other kind of storage (its not broken yet) and replace your unraid drive with a fresh one that comes out of multuple preclear cycles without any issues..

I would try another pre-clear cycle. Each cycle so far has uncovered additional un-readable sectors. If that continues, the drive is not one I'd want in my array. On the other hand, I've got one drive with 100 re-allocated sectors that has never changed from the first pre-clear I ran it through. Since it is stable, I trust it. Joe L. Quote Link to comment

khuong Posted April 3, 2012 Share Posted April 3, 2012 Hey Joe / Others, I just finished preclearing another set of drives (4x2TB Seagate Drives), got some different results then the first 2 drives I pre-cleared (WD EARX), wondering if these are okay, they look okay to me, except for the "near_thresh". Please let me know if I should add them to array (3 for data, 1 for parity). Also on a side note, I have another drive, that I was planning on using for CACHE, should I preclear it? Thanks again.

RPTS from previous post ^^ (Not sure if you require the start reports, they look really similar to the finished ones so I omitted them) the reports all look fine. Yes, I would pre-clear the cache drive to ensure it does not have any issues. (not because it will save time when adding it to an array) Quote Link to comment

It has nothing to do with the three disk limit of the free version of unRAID since you are never assigning the disks to the array. The three disk limit is how many disks you can assign to an unRAID array on the disk assignment screen, not how many you can attach to disk controllers in a given server. Joe L. Quote Link to comment
powerchoke Posted April 5, 2012 Share Posted April 5, 2012 I just completed the first preclear runs on two Seagate ST2000DM001's and had results nearly identical to khuong's. I, too, am concerned about the near_thresh report by preclear for Spin_Retry_Count and End-to-End_Error. These are both brand new hdd's - why such high thresholds for these parameters? Also, there was no diff between pre- and post- read for these values so I'm guessing it's reported in the 'Changed' summary because the values are close to the threshold values. ============================================================================ ** Changed attributes in files: /tmp/smart_start_sda /tmp/smart_finish_sda ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VALUE Raw_Read_Error_Rate = 112 100 6 ok 42522288 Spin_Retry_Count = 100 100 97 near_thresh 0 End-to-End_Error = 100 100 99 near_thresh 0 High_Fly_Writes = 99 100 0 ok 1 Airflow_Temperature_Cel = 66 71 45 near_thresh 34 Temperature_Celsius = 34 29 0 ok 34 No SMART attributes are FAILING_NOW Thanks Joe for the excellent script!

RobJ Posted April 6, 2012 Share Posted April 6, 2012 To powerchoke and khuong (and any others worried about these 'near_thresh' alerts) - you can safely ignore them. Joe very helpfully simplified the SMART reports and their before/after attribute changes, and added the 'near_thresh' alert to help users note any attributes that appeared to be degrading, approaching their failure threshold. What he could not have foreseen was a silly SMART engineer at one of the hard disk manufacturers setting thresholds in the 90's! I mean, setting End-to-End_Error with a starting perfect scale value at 100, then the failure point at 99! There clearly is no margin for error there, so this is (like several others) somewhat experimental, and not something to worry about. The End-to-End_Error attribute is not a critical item, is flagged as Old_age, not Pre_fail. On the other hand, Spin_Retry_Count IS a critical item, so a failure threshold of 97 is unusual, considerably higher than I have seen any where else. Such a narrow margin of error may indicate some 'fragility' in this aspect of the drive. The implication is that as soon as it begins to show any Spin_Retry_Count issues at all, then the drive is very close to catastrophic failure. Just a reminder, Pre_fail attributes are the only ones that are considered critical, the only ones that affect the SMART pass/fail test. The other attributes (flagged as Old_age) are either informational or 'aging' items. They are similar to human aging attributes such as wrinkling, arthritic joints, lost teeth, grey hair or balding, etc. Critical attributes would be a heart beat, breathing rate, brain wave activity, successful Alzheimers test results, etc. You may have increasing aging attributes, be a little slower, have small memory issues, but so long as you can pass ALL of the critical attributes, you are still a productive entity. Hard disks are the same. A suggestion to Joe, perhaps the near_thresh test and indication should be skipped for certain attributes. I would suggest skipping any that are not Pre_fail, and any whose THRESH is 70 or higher, and perhaps any whose VALUE is 100 or higher. Edit: I should not have raised any concern about the 'fragility' of these drives. Time will tell what these high threshold values actually mean. It is possible that the drive engineers are now so confident in the robustness of these drives, that they don't expect these problems (Spin_Retry and End_to_end) to ever occur again!

powerchoke Posted April 6, 2012 Share Posted April 6, 2012 Thanks for the response RobJ. I'm going to run preclear two more times over the weekend and if everything checks out I'll install them. BTW, preclear took just over 19hrs to complete both drives (in parallel). Quote Link to comment
mortstar Posted April 12, 2012 Share Posted April 12, 2012 I have two WD10EADS drives that I have been using in a D-Link DNS-323 for about two years. I would like to move one to my new Unraid box and leave one in the DNS-323 for backups of system images, unrecoverable personal media (which will be primarily hosted on the Unraid box). From my amateur eye, the HDD WD-WCAU45276695 is healthier as it had 0 re-allocations before or during the pre-clear cycles, whilst WD-WCAU45501747 had 297 re-allocated sectors. Is this a correct reading of these results? Can I trust WD-WCAU45501747 to hold my backup data in the DNS-323?

Helmonder Posted April 12, 2012 Share Posted April 12, 2012 Reallocated sectors are not a good sign, I would not use this disk in your unraid system. The number is also quite high, some people would advise to do a few more preclear cycles on the disk to see if the system is stable with this amount of errors or deteriorates. Most however do agree in just not using these disks, in most cases this is a sign of a disk that is going to fail on the short term. Quote Link to comment
VelcroBP Posted April 16, 2012 Share Posted April 16, 2012 First build, First Preclear. I'm completely new to this so I have no real idea how to interpret my results. I don't believe there were any re allocations or other errors to be concerned about reported, but I though I would post my results for review just to be certain before I add these drives to the array and start transferring files. I'm starting with 3 drives, a Seagate ST2000DL003 and 2 Hitachi Desktar 5k3000s. I will use one of the Hitachis as the parity drive once all my data is copied.

All the sectors that had been marked as un-readable were able to be written to their original sectors and not re-allocated. That would indicate a problem when they were originally written.

They would have had to have been identified during the post-read phase. That, combine with the two failed "short tests" indicates you need to go through another pre-clear cycle before trusting the disk in your array. next time, you should post the pre-clear report, not just a smartctl report, as it will show more of how the disk changed during the process.
