    [maybe solved]Array not responsive during a parity check with V6

    in General Support

    Posted

     

    But this is true regardless of which version of UnRAID you're using, so I'm a bit surprised the slowdown seem notably worse than it was with v5.    Did you have your "disk tunables" optimized with v5?  ... it could simply be that these are different with v6, and this is impacting the buffering for read/write operations and thus causing different performance during times when the disks are VERY busy.

    Since I don't know what "disk tunables" was for V5..  My guess is I didn't have it.  I did have the: 

    for i in /dev/md*
do
echo Setting $i
  blockdev --setra 2048 $i
  blockdev --getra $i
done

     

    In the go file for V5..  But I don't have it for V6.  Has anyone shown that it makes a difference?

     

    And I guess I should look up disk tunables?

     

    Thanks,

    How to adjust speedstep speeds?

    in General Support

    Posted

    Ok..  I had the bios specifically slow down the CPU.  I did that because I didn't need the HP and to save power.  But now with V6 it seems I DO need the HP! So I bumped it up to the default.

     

    So my question still stands!  How does The kernel decide what the fastest and slowest speeds are for CPU?  Right now there are two speeds, 2.5G and 1.6G

    I'd like to slow down even further.  How do I do this?

     

    Thanks,

    [maybe solved]Array not responsive during a parity check with V6

    Ok..  so I solved/improved my parity check speed by changing to a 2 core processor...  see here. but now my array isn't responsive while doing a parity check.  It's reallly sssssllllloooooowwww when accessing files.  My automatic acronis backup

    fails when before it would happen just fine during a parity check with V5.

    Is there some way to lower the priority of the parity check or something else I can do?  I can't really have the array non responsive while the parity check is going on.

    I mean I can tolerate some slowness..  but if programs fail then that's just not good.

    I just put in a core2duo to replace my older celeron. (until I can upgrade the whole system)

    It has two cores with speedstep.  I'm trying to figure out how it determines to change the speed?

    The dashboard has both cores at 1200MHz at idle and rams them up to 1700MHz under load (parity test)  I think my cpu is capable of 2300MHz?

     

    Why didn't it go to 2300?  can I set the min to be lower than 1200?  like maybe 800MHz?

    Where are these things set?

     

    Thanks,

    disk got a bunch of read errors!  Will this disk now be red balled?
    Theoretically the drive accepted the writes to replace the data that could not be read. When a drive has read errors, unraid reads all the other drives and calculates what should have been in the location that had read errors, and issues a write command to put the data that couldn't be read back onto the drive. If the write fails, the drive is red balled (X'ed?) otherwise if the write returns success, the drive stays in service and the error count for that drive is incremented.

     

    I'd disable spindown for that drive and run a long smart test, then get a smart report and post it.

     

    If you want help deciding what drive needs to be replaced next, get smart reports on all your drives and post them.

    Thanks!  So if the drive's not redballed now it should be there on a restart, right?

    Now does the long smart test have to be done with the array offline?

     

    And how can I just *read* everything on the drive to see if I get the errors again? something like dd to /dev/null.

    Aww crud..  I start a parity check because I just upgraded to V6.1 and I was testing speeds and I had a couple drives with a current sector pending.  one went away..  but another disk got a bunch of read errors!  Will this disk now be red balled?  The parity check didn't get any errors.  but I got 113 read errors.

    What should I do?  Since the parity check didn't give any errors??

    The disk is 5 years old.. but I have a couple that are 6 that are next in line to be replaced..

    The V6 version isn't installed from unmenu..  from my experience...

     

    I got mine from here:

     

    http://lime-technology.com/forum/index.php?topic=31735.0

     

    For V6:

    Paste this line into the 'Install Plugin' line in the 'Plugins' webgui and click on install.  This will install the plugin.  Don't install the plugin manually.  Let the plugin manager handle it.

     

    [Solved] Parity check about 1/2 the speed with V6...

    in General Support

    Posted

    I just installed the latest V6.1 and tried a parity check...  I'm getting about ~22-24MB/sec.

    It says it will take 2 days to  complete!!

    With V5 it's never taken 2 days!

    Is V6 expected to be slower?  My CPU is pegged.

     

    What could be going on here?

     

    I had this in my old go file... Does it need to be in the new one as well?

    for i in /dev/md*
do
echo Setting $i
  blockdev --setra 2048 $i
  blockdev --getra $i
done

    Basically..  MyMain is the only thing I'm looking for.  I really like the fact that I can change the view..  like with the inventory I can set and view all my purchase dates and info and set usage notes..  I also use the network view sometimes.

     

    I agree the V6 GUI is a much improved interface..  but nothing still beats "MyMain"

     

    Oh..  I also like the color coded syslog too of unmenu!! :-)

     

     

    CPU Utilization too high??

    in General Support

    Posted

    More info...

     

    I found the CPU info it's

    Intel Celeron 430 Conroe-L Single-Core 1.8 GHz LGA 775 35W BX80557430 Processor

     

    So it is only Single core.  I think I bought it because it was low power...  But now maybe it's too old?  Does it not have enough juice now?

    I bought it back in July of 2009!!!  I thought it was only 2 years old...  but I guess it's much older..

     

    New Question.....

     

    If I get a new MB/CPU..  Will my power consumption be less (taking the drives out of the equation)??  With all the throttling?

     

    Thanks,

    What should my CPU utilization be?  I'm copying some files and my CPU (according to the dash board is 90-100%)

    SHould it be that high

    The dash board says the core is running at 1800MHz

     

    After the copy finished, The CPU is still about 60%?

     

    I just upgraded to V6 from V5.05 and I'm wondering if this is normal?  I can't remember what my old CPU utilization was...

     

    How can I tell  how many cores I have and what model of CPU?  I honestly can remember! :-)

     

    Thanks,
