Nothing too bad, other than the second drive looks like it has been bounced a bit at some point in its past:

G-Sense_Error_Rate      0x0022  100  100  000    Old_age  Always      -      3

 

thanks for doing what you do Joe!  Still waiting on the WD's to finish. I'll post those too. Again - I appreciate you going through these for me.

 

I'm thinking of keeping 1 of the WDs as a warm spare ... keep it pre-cleared, and attached, but not in array until either I run out of space or one of my other drives fail. I saw that idea floated around somewhere, I can't take the credit for it.

We'll see what the disk looks like after the preclear. 

 

It shows 0 sectors re-allocated.  (That is good, as it indicates the disk has been able to write successfully to the original sector.)

It shows 6 sectors pending re-allocation.  (This is bad, as it indicates they were identified in the most recent pass of the badblocks program...)

It shows 150 reallocation events, which again indicates a constant trickle of sectors that are unreadable, but can be written in place.  (the original "writes" to those blocks were marginal)

 

Now, this can all be explained by either a defective disk drive, OR a drive that is sensitive to power supply noise or low voltages.  (as when supplied on either a marginal supply, or connected through a number of high-resistance connectors/splitters, or sharing a power supply rail with a lot of other drives)    In other words, if you can, try a different power connection.

 

Did I ask you yet? What specific make/model power supply are you using?  And what mix of disks are you powering?

sadly, still sectors need to be re-allocated :(

6 sectors were pending re-allocation before the start of the preclear.

0 sectors were pending re-allocation after zero of disk in cycle 1 of 1.

10 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 are re-allocated at the end of the preclear,

I guess I'm gonna just have to order a new drive.

damnit - the slow read keeps coming back from time to time.

 

syslog attached... sorry it's a 7zip, renamed to .zip

I would guess you are maxing out your BR10i.

 

yeah - i'm thinking that... surprised, but i guess that's the roll of the dice. I wonder if the whole array not assigned thing is causing issues also..

That is what I'd do.

 

Well, I don't generally like the idea of using adaptors or splitters for powering the drives, and the SATA cables on my current power supply only have 3 SATA connectors on each cable, but I have 4 drives in each rack, so it's a bit convoluted to connect power to all the drives as it sits; so... I bought a new 650W modular supply with 2 cables with 4 SATA  connectors each, and am ordering a third cable with 4 connectors, which will allow me to connect all 12 drives directly to the PS without any adaptors.  It will also provide more power, which I doubt I need, but it was the only PS that had the cabling that I needed at the best price, and it's GOLD certified, so it should be more efficient.

 

Once I get the new PS, I'll replace the old one, and get all the drives connected and see if that helps my issues.  I doubt this will resolve everything, but it will eliminate the PS as a potential source of the problem, and will make future usage easier for me also.

 

I'm running a preclear on the 3TB drive now, and hope that this time it finishes without problem, since I REALLY need to get some files moved to make space on the existing drives soon.

I started preclearing a new 4TB Hitachi drive yesterday, I do not do this weekly so I would like to verify:

 

I am at 36% of phase 1 at the moment and this has taken a little over 26 hours...

 

Sounds a bit long not ?

 

Specific command: preclear_disk.sh -w 65536 -r 65536 -b 200 -c 3 /dev/sdc

 

First time I use the commands Joe provided to reduce effect on memory, can it be that those same paramters make the process longer like this ? Speed is like 50 to 60 MB/s

Go back to page 73 of this thread for more discussion of these parameters. I was trying to do 3TB. Increased -b parameter is what you need.

Did that but did not find anything concerning a -b parameter... Since there does appear to be a relation with these parameters (I conclude this from your reply) I will take my chances and do the preclear without the extra parameters, if only to see if that makes the difference..

Sorry, wrong thread. Try this instead.

When I tried it on 3TB with the defaults (no parameters) I ran out of memory. The originally suggested -b 200 parameter was too conservative and caused it to be very slow. -b 256000 was suggested and I stopped mine during post-read and restarted it like this.

I have no experience with 3TB drives, nor with your disk controllers (whatever they might be, odds are they are not the same as my older motherboard's)

Smaller blocks sizes will slow things down some, as more calls to read the disk must occur.  If you are getting 50MB/s, then it will take 20 seconds per GB to read the disk.  You have 4000 GB to read ( 4000 * 20 = 80,000 seconds = 22.22 hours )  At 26 hours, I'd say something is slowing you down... (buss bandwidth, or disk controller bandwidth) or there are errors showing in your syslog and the disk controller keeps re-setting the disk in an attempt to keep going.

 

Most people get around 100MB/s on the outer cylinders of a disk and 50 to 60 MB/s on the inner cylinders.

I just finished the preclear on the 3TB drive (not the 1TB drive we had been discussing recently).  here is the original/first preclear of this drive, which was done simultaneously with the 1TB drive, and with SABnzbd downloading all at the same time...

It looks like this drive is okay, and can be put into production.  Is that an accurate assessment?

 

You suggested earlier that it might be  power supply issue causing the issues with the preclear of the 1TB drive, which might have also been the cause of the re-allocated sectors of this drive, I suppose.

 

I'm betting you're going to suggest that I do one more preclear to confirm that there are no issues one more time, but I'm out of space, and don't want to wait another 35 hours to put this disk to use, unless you really think it's necessary.  Is it?

Hi, I just precleared my first hard drive and I think everything looks good, but can I get a confirmation?  Thank you!

What does the "End-to-End_Error" ?  Should I use the disk ?

 

BTW. I shouldn't use the -A option when using 3 TB+ drives, right?

Well, other than the raw value (Which apparently isn't always a decimal number, so, whoopy) it looks good, although, can someone verify this:-

Yes, I do notice the:-

==> WARNING: There are known problems with these drives,
AND THIS FIRMWARE VERSION IS AFFECTED,
see the following Seagate web pages:

http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207969

 

But I've used this drive for > 3 years and it hasn't locked up yet, if it does, I guess I'll just have to replace it.

Hey!

 

Even though I've already pre-cleared some hard drives, I have a question about this result.

What does the "End-to-End_Error" ?  Should I use the disk ?

 

BTW. I shouldn't use the -A option when using 3 TB+ drives, right?

It indicated the disk has failed.!!  The data sent to it did not match that written to the disk.. (probably bad internal memory or electronics on the disk)  It is FAILING_NOW, therefore, you should NOT use that disk.

 

RMA it.

 

The "-a or -A" are meaningless on disks larger than 2.2TB and ignored, even if you supply them as command arguments.

This is not good:

Spin_Retry_Count        0x0013  100  100  097    Pre-fail  Always      -      2

twice (so far) the disk was not able to spin up to speed.  Typically, it indicates significant mechanical wear.

 

There is also a lot of hardware error correction taking place.  Notice now the normalized value (46) is getting closer to the failure threshold (0) and the "worst" value (14) is very close.

If the spin-retry-count gets higher I'll start taking it as a serious number, but, I've been monitoring these drives for the last 3 months (On my desktop) and it hasn't increased recently, so, for all I know it may have been right as I was placing it in it had a dodgy PSU connection/etc. When I first got this drive I didn't do any real tests on it at-all until ~ 3 months ago. As for the Hardware_ECC, can you explain what that does? Wikipedia just says:-

(Vendor specific raw value.) The raw value has different structure for different vendors and is often not meaningful as a decimal number.

 

Only reason why I'm not so eager to take it out of my array is because I obviously no longer have any warrant on it (Had it for 3 years+) so, it's either in my array or being used for nothing.
