Preclear.sh results - Questions about your results? Post them here.


Recommended Posts

currently running a second pass now. I skipped the pre-read and went straight to writing zero's first.

Since it just finished a post-read, that should do.  I noticed it originally had 5 sectors pending re-allocation, and they were all re-allocated when writing zeros, but then in the post-read, 13 more were identified as un-readable....

 

We'll see what happens this time.

I'm preclearing my first 3.0TB drive using preclear v1.13, and prior to starting the preclear it says that the cleared drive size will be 2.2TB.  Is that actually going to be the final size after preclear, or is that just the way preclear needs to handle larger drives and reports it smaller than it really is?

 

This is on a system running 5.0-beta12a with 2x BR10i controllers (with the latest firmware flash from this thread - http://lime-technology.com/forum/index.php?topic=12767.0).

It will report the partition as 2.2TB to older utilities. 

 

I've never seen the message you described, but them I've never seen a 3TB drive  ;)

Probably just how "fdisk" is describing it. (and fdisk is an older utility)  Don't worry though, the preclear script does not use "fdisk" to actually create a partition.

this is all over the syslog at the time the preclear failed.

i think this one's going to be RMA'd.

this is all over the syslog at the time the preclear failed.

snipped ...

 

the drive later got re-assigned sdi from sdh.

snipped ...

 

i think this one's going to be RMA'd.

 

At 'Apr 20 03:15:57', the drive stopped responding to commands.  A hard reset was sent, and the SATA Link reported no problems, was full speed at 3.0gbps, but there was still no response to higher level queries over that link, not even identity info.  After more hard resets with similar results, the SATA link was slowed to 1.5, to see if that might make a difference, but unsuccessful too.  So at 'Apr 20 03:16:52', Linux marks the drive device sdh as disabled.  Once a device has been marked as disabled, I have never yet seen a recovery, until next boot.  And you can completely ignore all of the subsequent error messages and actions related to that drive (including that second section you quoted).  It does look like the kernel successfully recovered the drive later, and even read the partition table, but it was too late.  It was as a new device sdi, which unRAID and Preclear knew nothing about.  After a reboot, everything should have appeared to be fine, except that Preclear had to abort.

 

In my experience, a drive disabled this way is usually not at fault for the trouble.  It is generally an issue related to the driver or cable or controller card, or possibly a power issue.  So no, this particular problem would not be a reason to RMA the drive.

 

However, the syslog and SMART and Preclear reports you have provided do show an ongoing series of problematic (possibly bad) sectors, media errors.  Another Preclear is very necessary, and if it is perfect (no further pending or remapped sectors), then I would recommend an additional Preclear, just to see if it too is clean.  I think I would only trust this drive if it can perfectly pass 2 consecutive Preclears.  A drive that keeps finding new bad sectors on each pass, that are never the same, seems very suspicious to me.

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.

 

This keeps coming up, and I have been thinking about it, and wrote up some thoughts, perhaps for a future SMART wiki page.  I don't know if this is an appropriate place for them, so I apologize in advance to Joe L.  My thoughts below: (apologies also for the lack of clarity in my writing)

 

 

I've noticed that users generally feel that a newly acquired drive that does not maintain a perfect SMART report in its first week is worth much less than a drive that remains perfect, SMART-wise.  In addition, users often consider any drive with a significant number of remapped sectors to be suspect.  To a large extent, that makes sense, and yet I have had doubts as to the significance of a perfect SMART report.

 

[speculative]

Sometimes I wonder if the "0 sectors reallocated" is a real zero, or a normalized base line of zero.  In other words, are these drives really that perfect, with all tracks and sectors completely contiguous?  Or is it possible that they have initialized the starting drive maps so that, after initial testing, they only include sectors that have passed testing?  If so, then an initial value of zero bad sectors is not very meaningful, and furthermore, we should probably not be that concerned with a few bad sectors that appear in the first month of a drive's life.

 

It is easy to speculate that what actually happens is more like this:  engineering tests determine that a new drive can potentially carry X number of tracks (for illustration we will use the number 5300).  Management says they want a drive of size Y, which will require 5000 tracks, plus an extra 100 tracks reserved for spare sectors.  So an initialization program is set up to install the firmware, do the basic tests of the drive, and then initialize the starting drive maps by locating the best 5100 tracks of those 5300, and then reserve a hundred for spare sectors.  In other words, there could well be a number of tracks skipped, perhaps only because they had a single sector that seemed questionable.  How would we know the difference, between this and a pristine totally contiguous drive?  We wouldn't!  The initial SMART values would be cleared, and appear perfect.  From your experience with manufacturers in general, would you not say that monetary and marketing factors are more likely to drive product design than other factors?  It does make sense from a practical point of view, so I personally think this is a likely scenario.  All of which makes the current value of remapped sectors somewhat meaningless, so long as the number is not changing.  [Disclaimer: this is all speculation, I have no inside knowledge, and it is possible that the platters are actually made so well, so consistent (over-engineered?) that they usually ARE near perfect.]

 

And I don't know that this really matters either.  I like the current setup, where you acquire an apparently pristine drive, that includes a relatively large number of spares to replace any that suffer 'infant mortality' plus more for the long term loss due to wear and tear or whatever.

[/speculative]

 

The important thing therefore may not be to focus too much on the current number of reallocated sectors, zero or otherwise, but on whether the number is growing.  A growing number is always concerning, but once our testing appears to show that the number has plateaued (no change at all), then the drive should again regain our confidence.  I think an enormous number of drives have been returned, that may have had many reliable years left in them.

a very nice summary.    Nobody knows if a drive with 0 re-allocated sectors is actually defect free, or just set to zero by the manufacturer after mapping an initial set of defects.

 

I can not know for sure, but the facts I know are that it takes a finite amount of time to read all the sectors of a disk.    I know we can read at roughly 100MB/s.  I have no idea what the speed of an internal only test might be.  Whatever it is, it must be very similar to a "long" test as issued by the smartctl utility.

 

I'm not sure that each disk is actually tested to see that every bit is readable.  With that in mind, does each drive sit on the manufacturing line for the 4 to 6 hours needed for a full test?  Nobody knows except the manufacturer.  I doubt the drives are tested for that length of time... it would limit the number of drives you could manufacture, as the tests would take FAR longer than the actual assembly time.

Yes, 4 to 6 hours does seem like a significant limiting factor in manufacturing them, but don't they already have to low-level format them?  I don't know for sure, but it seems reasonable to me that their formatting machines are testing while writing.

 

I suspect that they are using proprietary machines much faster than our consumer drives, perhaps multi-headed.  If I were there, I would want the engineers to design a drive without the common single-headed swing arm, and use something like a sliding bar perpendicular to the tracks, crammed with all the heads that can fit on it, each wired for simultaneous read/write, plus multi-threaded software to simultaneously operate each head, plus a high speed bus to handle all that I/O.  If you could cram heads 3mm apart, then the bar only has to slide 3mm in a radial direction for heads to reach every track.  That would be about 8 heads per inch, giving you 10 to 15 heads to speed up the formatting, and 6 hours goes down to about half an hour.  And if they can double or triple the rotational speed ...  Speculating again...

 

Testing could be as simple as reading the track immediately after writing the formatting, before moving to another track.  With our consumer drives, that would certainly slow the process down, but if we add a second head bar to our hypothetical machine, so that it reads after the first set of heads write, then there is almost no extra time required.  I'm sure they don't need my ideas(!), but I do think they must have much faster machines than we do.

Hi,

 

I'm new to unRaid and having been reading through the various FAQ's and Configuration Tutorials and was running the preclear on 3 WD20EARX drives (2TB).  I had it running from around 10pm on Tuesday  night (4/24/12). The three drives were setup to run preclear at the console (not telnet).  Various times i checked on the status they were running, however when I came home from work today at around 7.30pm (4/25/12) I saw that the VTerm  seemed to be showing error messages with a bunch of text. I couldn't switch to the different VTerminals using Alt+F1/F2/F3.  Basically the system seemed frozen with a blinking cursor, keyboard would not respond and I couldn't connect via a web browser from my laptop.  I was only able to take a picture since the keyboard wouldn't respond, so no logs.  Can anyone decipher what the screenshot is indicating?  I restarted the preclearing on all 3 drives again hoping it was just a fluke or something. 

 

I have a HP Proliant NL40 with 8GB RAM and 3 WD20EARX (2TB drives).  Lenovo USB flash drive (1GB) with the latest beta version of unRaid 5.0.14 Beta. I used the -A for preclearing also.

 

Picture was too big too attach so hopefully the links below work.

 

TIA

*EDIT* checked status again and its happened again, same or similar screen... but this time within the last 2hrs preclear was running.  Should I try running preclear on one drive at a time?

Hey guys,

 

I think I've got a drive on its way to being a dud by the looks of this - just took 4 of these drives out of a Readynas NV+ and dropped them into unRAID and this one turned up suspect.  They'd been running fine for the last 2 years or so.  Can someone with better knowledge than I make comment on the results?  I'm running another preclear on it now in any case.

basically, you crashed.  (probably ran out of free memory)

 

The dump seems to indicate the kernel was attempting to find the lru (least recently used) page of memory so it could re-use it.

 

Joe L.

 

Thanks for the reply Joe.

 

Is that normal to run out of memory for 3 preclears running at the same time? I have 8GB RAM in the server and only did it because the FAQ mentioned 4 or more preclears shouldn't be run at the same time.  After the second crash, I formatted the usb drive and reloaded again from scratch.  I just started the preclear on one drive only.  As of 7am this morning it seems to be still going so hopefully it'll go ok all the way till the end and I can start the 2nd one tonight.

The dump seems to indicate the kernel was attempting to find the lru (least recently used) page of memory so it could re-use it.

Thanks for the reply Joe.

 

Is that normal to run out of memory for 3 preclears running at the same time? I have 8GB RAM in the server and only did it because the FAQ mentioned 4 or more preclears shouldn't be run at the same time.  After the second crash, I formatted the usb drive and reloaded again from scratch.  I just started the preclear on one drive only.  As of 7am this morning it seems to be still going so hopefully it'll go ok all the way till the end and I can start the 2nd one tonight.

I've got absolutely no idea.  It would depend on lots of factors.

I would not have thought you would have issues... but I was not the one who wrote that part of the wiki.

 

If your syslog filled with errors, that could use up all your memory.  If you were performing a parity check/sync, all available memory would be used as cache. (unless you have more RAM than disk space)

 

I would run a

tail -f /var/log/syslog

and see if anything is filling it.

 

I would also perform a memory test, if you have not done one... who knows, you might have less RAM than you think.

Hey guys,

 

I think I've got a drive on its way to being a dud by the looks of this - just took 4 of these drives out of a Readynas NV+ and dropped them into unRAID and this one turned up suspect.  They'd been running fine for the last 2 years or so.  Can someone with better knowledge than I make comment on the results?  I'm running another preclear on it now in any case.

 

Unless something turns up on the next Preclear report for this drive, the drive should be fine.

 

If you examine the SMART report you attached, you can see that the drive has almost 12000 hours of usage (Power_On_Hours = 11826), and the last UNC error (UNCorrectable media error - data in a sector too scrambled for ECC info to correct) was at 1428 hours, perhaps 2 to 6 months after you acquired the drive and over 10000 usage hours ago.  The drive does report 13 UNC errors, which corresponds to the 13 errors in the SMART log.  The log only shows the last 5, but you can see that at 1428 hours, 3 UNC errors occurred, 2 of which are repeats of the 2 errors preceding (error #9 and #10).  We cannot see errors 1 through 8, but we know that they were UNC errors like the 5 we CAN see, and we know that they occurred no later than hour 53, which is within the first 3 days of drive usage.  So you have been using the drive for over 10000 hours without any issues, and that is why I think the drive is fine pending any adverse results from the Preclear of it.  The writing of zeroes to the entire drive should make any issues visible.

 

The fact that 2 (at least) sectors have appeared twice (at differing times) to be UNC does seem a little suspicious, so the media surface under them may be a little weak.  Ideally (I think), Preclear will force the drive to discover and remap them.  That would result in a few Reallocated sectors, but if a subsequent Preclear is clear with no further changes, then the drive should be very good, and you would no longer even have to worry about weak sectors.

A week or so ago I noticed that one of my drives (disk1) was showing sectors pending reallocation, the disk was also one of my oldest and has made over 20,000 hours.

 

I figured a replace was in order, I have been running flawlessly with v5b14 and want to be ready for the future, a 3TB replacement was in order.

 

I started a replacement caroussel:

 

- Bought new 3TB Hitachi

- Precleared 3TB with 3 cycles, flawless !

- Replaced 2TB parity (that was flawless) with 3TB

- Precleared old parity 2TB 3 cycles, flawless !

- Replaced my "failing" disk1 with the old parity disk

 

Everything worked as expected, no stress !

 

Then I started a 3 cycle preclear on the old disk1 fully expecting to have it "fail" on me. Results were as followed:

 

============================================================================
** Changed attributes in files: /tmp/smart_start_sdd  /tmp/smart_finish_sdd
                ATTRIBUTE   NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS      RAW_VALUE
      Temperature_Celsius =   117     125            0        ok          35
No SMART attributes are FAILING_NOW

4 sectors were pending re-allocation before the start of the preclear.
4 sectors were pending re-allocation after pre-read in cycle 1 of 3.
0 sectors were pending re-allocation after zero of disk in cycle 1 of 3.
0 sectors were pending re-allocation after post-read in cycle 1 of 3.
0 sectors were pending re-allocation after zero of disk in cycle 2 of 3.
1 sector was pending re-allocation after post-read in cycle 2 of 3.
0 sectors were pending re-allocation after zero of disk in cycle 3 of 3.
0 sectors are pending re-allocation at the end of the preclear,
    a change of -4 in the number of sectors pending re-allocation.
0 sectors had been re-allocated before the start of the preclear.
0 sectors are re-allocated at the end of the preclear,
    the number of sectors re-allocated did not change.

 

My question: Should I continue to use the old disk1 or should I retire it ?  More then happy to add it to the array for extra space (though I do not really need it at the moment.

 

What confuses me is that there are changes in re-allocation during the cycle but preclear states it has "passed". I thought that such "changing" behavious most likely pointed towards a disk going to fail ?

Well... the original 4 sectors were apparently re-written in place, and not re-allocated, but then on the second cycle one additional sector was not readable initially, but re-written in  place on the zeroing phase.

 

I'd run it through another few cycles.  If it still has an occasional sector show as un-readable, I'd not trust it for anything critical.

 

If it is all OK, then go ahead and use it if you like... (Or RMA it, if in warranty)  Of course, you can always put it in a windows OS, and blame any future data corruption on Microsoft.  ;)
