Well Joe, I need your advice.  Attached is the syslog after I precleared a brand new 2 TB WD EARS w/ jumper.  It took 64 hours to complete!  I figure something must be wrong for it to take that long.

 

First off, I know I have HPA on some of my drives.  I no longer use a gigabyte mobo and I haven't bothered to get rid of them.

 

Some things I've noticed:

Two of my drives (one of which is this new 2 TB WD EARS) are in IDE emulation mode even though I have AHCI turned on in the BIOS.  Any idea why?  I'm using a Promise TX4 card, do I need to do some special configuration for that?

...and then two read errors and two pending sectors.

 

Looks like I may need to RMA this drive?

I doubt that 2 re-allocated sectors would qualify you for an RMA.  They'd laugh at you since modern drives of that size have several thousand spare sectors, and your SMART report "normalized" value of 200 is nowhere near the failure threshold of "0"

 

In the same way, the read error rate of "200" is nowhere near its failure threshold.  All drives have read errors, some report it, some do not, most will re-try several times before determining a sector is un-readable.

 

As far as IDE vs SATA there is a second setting in your BIOS you need to set to get the drive out of the "legacy" mode.  It is probably the root cause of the difference in performance.

Great, thanks for the good news Joe.

 

Edit: I determined that it is the Promixe TX4 card that has both of it's drives in IDE mode.  The card has no BIOS screen of its own, and I can't figure out how to control it via the motherboard's BIOS settings (all of which are correct, by the way).  I plan on migrating my server to my 4220 + AOC-SASLP-MV8 setup soon, so I guess I won't worry about it.

Hi!

I tried to run two sessions of telnet via wireless and ran preclear on two different harddrives. One hdd (WD 1 Gb) reportet finished within 15 minutes. I know something is wrong because it took over 12 hours on other drives.

I tried to re-run preclear, but it couldn't read any driveinfo.

I am a linux newb, so will someone please tell me what went wrong?

 

Kind regards

Henrik

looks like communications with the drive is failing.

 

Might try a different SATA cable, or re-seat the existing cable to the drive. You have lots of BadCRC  errors.

I have a newbie question.  I ran preclear on a new 2 TB western digital (ears with 7+8 jumpered) from the console on the unraid box itself. there are SMART differences listed, but most of the report is off the top of the screen.  are the results written anywhere that I can look at them.  I usually run it from a terminal window on my linux  desktop where I can scroll up, copy/paste, etc.  i don't want to have to run this again.

 

thanks,

The two SMART reports were logged to your syslog.

 

You can scroll up on the system console...  (Shift-PageUp and Shift-PageDown)

No, the preclear did not take 7 months....my clock got reset when putting in the new drive, and in the meantime, the clock got updated.

 

Looks good to me unless somone tells me otherwise.

Nothing looks weird to me.

 

What looks weird to you?

OK...pre-clearing 3 disks.

1 completed and I would think is good.

 

Other 2 were at 98% and 96% of post-read phase when had a storm power outage.

 

This is not on UPS (but I see the value in getting one now) so naturally the starting SMART logs no longer exist.

 

Attached is the output from smartctl -a /dev/sd[a,b]

 

As much as I know, they look good.

So what should really be paid attention to??  reallocate, error_rate, what else?

 

So would you figure they are good or recommend going thru the pre-clear process again for them?

Thanks in advance.

Nothing looks weird to me.

 

What looks weird to you?

was weird, but if there is nothing to worry about I'm cool. Thanks.

It indicates the manufacturer has not told anybody about what those two parameters represent, but that their "normalized" value of  200 is nowhere near their failure threshold of "000"

Hi!

 

I'm currently preclearing a new Samsung 2TB drive and it really takes forever. The post-read is still in progress and over 29 hours have elapsed since I've started preclear. Is it normal that it takes that long to preclear a drive? And is it also normal that the read speed drops from around 105 MB/s to 50 MB/s?

Similiar to my just preclearing 2 WD 2TB drives.  From other readings, the speed difference is normal due to where on the platter you are reading.  Joe could give a better explanation than I.

 

Since you are in the post-read, you could calculate the estimated time remaining by taking the full size in bytes minus already read, divide that by 1048576 to get MB, then divide that by 50MB/s (or whatever your current speed is) which will give you seconds, divide that by 60 to get approx minutes left.

Yes.  Quite normal.  A 2TB drive usually takes between 33 and 36 hours depending on what else is going on on the server.  If you are doing a lot of other disk IO, it could take a bit longer.

And is it also normal that the read speed drops from around 105 MB/s to 50 MB/s?

Yes, also normal.  The inner cylinders on the disk do not hold as much data as the outer ones because their tracks are not as long, since the rotational speed is constant, the potential "read rate" of inner cylinders is always slower.

 

Let's assume an average "read" speed of 75 MB/s.  That means you'll read 1000 MB (1 GB) in 13.333 seconds.

We need to read 2000 GB (2TB) so, we would get at best 13.333 * 2000 seconds = 26,666.666 seconds

26,666 seconds = 444.44 minutes

444.44 minutes = 7.4 hours.

 

So, 7.4 hours roughly just to read the entire disk, and you cannot speed that up no matter what you do, and that does not count the time verifying the zeros were written properly in the post read phase.

Thanks for the replys. I knew that the speed varies depending where on the platter the disk is reading but I am surprised by the huge difference. It's down to 47 MB/s right now that's less than half the initial value.

 

But if that is normal  I'm reassured. Thanks again  :)

The circumference of those inner cylinders is a lot smaller than the outer.  The disk manufacturers like to boast about the peak speeds on the outer cylinders, they seldom talk about the slower sustained speeds on the inner cylinders.  :'(

Another question :) The disk has been successfully precleared. It took 30 hours and 23 minutes.

 

But there are some SMART values which I'm not sure if they might indicate an issue.

 

< 1 Raw_Read_Error_Rate  0x002f  100  100  051  Pre-fail  Always - 2

> 1 Raw_Read_Error_Rate  0x002f  100  100  051  Pre-fail  Always - 4

 

Is this anything I have to worry about?
