Question about preclear_disk.sh speed

Featured Replies

Hello,

 

just got some new 3TB WD Drives. So I started a PreClear with the fist one.

What I'd like to know, I only get 2.6MBs preread Speed, any ideas?

 

I think, this is a Bit toooooo slow, or am I wrong?

 

I started PreClear with: preclear_disk.sh -A /dev/sdr

 

Controller: Supermicro AOC-SASLP-MV8

Disk: Western Digital WD30EZRX 3 TB (SATA 600, Caviar Green)

Unraid: UnRaid 5.beat14

 

 

One more thing,

 

I got my Preclear from the bottom of the fist post in the PreClera_Disk.sh  Thread.

http://lime-technology.com/forum/index.php?topic=2817.0

 

But when it starts, I see at the top right corner 1.13.

In the Thread a 1.6 is advised for 5.x but where can it be downloaded, or ist in the 1.6 just the old revision displayed?

    version 1.6 is 7 versions OLDER than version 1.13. 

     

    Use the version 1.13 attached to that post.  It is the latest at this time.

     

    Yes, 2.6MB/s seems a tiny bit slow.  1000 MB (1GB) would then take 384.61 seconds or 6.41 minutes.

     

    Since you have a 3TB drive, your pre-read (assuming it does not change speed) would then take

    6.41 minutes * 3000 = 19230.769 minutes, or 320.512 hours, which is roughly 13.35 days.

    Since the pre-read is usually 1/4 to 1/5th the total time, I expect your disk will be cleared somewhere around the first or second week in April.  :'(

     

    Have you looked in your syslog for any signs of errors.  Most drives can be read at somewhere between 50 and 100 MB/s.  Are you doing this while running a parity check or calc, on a PCI buss based machine, fully loaded with drives?

    Hello,

     

    to Your advice im using 1.13

    CPU: Intel i3 2120T

    Ram: Kingston HyperX DIMM 16 GB DDR3-1600 Quad-Kit

    Disk is attached to Controller_2

     

    Controller 2 / 3 have FW .21 - for the 3TB support.

     

    Now I tryed the same Drive via eSATA in an Sharkoon QuickPort Case... -> 117MBs

     

    OK, so any ideas?

    Cause I'll go crazy, when the Drives are turning to be that slow, when they are connectet to the SuperMicro Controller.... :'(

    try adding irqpoll to you syslinux.cfg file.

     

    like this:

    label unRAID OS                                                                                                                   
  menu default                                                                                                                    
  kernel bzimage                                                                                                                  
  append initrd=bzroot irqpoll rootdelay=10

    There is a known issue with those Asus P8 boards.

    They don't work with LSI raid cards (you don't have one).

    They are great desktop boards but they need some love to use as a server in my experience.

     

    The 3rd slot is shared with the USB3 and causes conflicts.

    try disabling everything in the bios you don't need, especially the USB3

     

    also, if you don't need the highpoint, I'd stick to 2X SASLP-MV8 and the 8 mobo ports.

    I'll give it a try.

     

    @Johnm

    USB3 and all other unused things like FireWire is disabled.

     

    As I'm hoping, that the numer of DataDrives is going up ::), I need every Sata Port I can get. 8)

     

    THX for Your Help!!
