    Long time lurker, first time poster. New build!

    in Hardware

    Posted

    Depending on the board you get, if it supports core unlocking you MAY be able to unlock a second core to squeeze out a little more juice if you ever need it. My board does support it and I've tested it, the CPU was stable with the second core unlocked, turned my Semron 145 into a Athlon II 4550E 2.8Ghz Dual Core Processor. By no means a powerhouse but a little extra kick. That being said, I do not run it unlocked and the single core sempron does its job nicely. Note I also run some addons too so that should tell you that it will be good for your build.

    Yeah I was reading about this. Sounds awesome and I'd like to take advantage of the unlocking, if possible. Do you have any idea if my proposed board will unlock the chip? I'm not sure how to tell. I would definitely pick a different board if it was the difference between being able to unlock the CPU or not. Here's what I was looking at from the original post: Asus M5A97.

     

    Don't do it! Well you can but if you do get a cpu with a disabled core make sure you test it for stability when you unlock it.  I unlocked the extra core on my AMD Sempron and everything seemed stable until parity calculations happened. Then I was getting 1in4 parity calculations as an error, took me days to figure out since the system seemed stable until then.

    You've managed to get a Raspberry Pi?  >:(

    Build looks good, I'd agree with neilt0 about the ram, a 4 GB kit cost around £18 at Scan.  I wouldnt worry about getting an IDE compatable motherboard, just buy the add on card and then get rid once your drives give out or you upgrade to sata drives.

    You shouldnt need any additional cooling as long as the ambient room temp isnt too high.  I kept my first sempron unraid in my bedroom at uni and it only needed the fans on while doing the parity check on warm days, was quiet too.

     

    [SOLVED] Increasing parity corrections over a month

    Have you tried reseating your RAM and all connections to harddrives?  They tend to be causes of most parity errors.

    I also had an issue getting thousands of errors, when I worked out the error rate it came out at 1 in 4 once the number stopped increasing.  After tearing my build apart and reinstalling everything I still got errors.  It was only by chance I remembered I had inlocked the 2nd core on an AMD Sempron 140.  Since my system was stable before I unlocked I hadnt bothered to check afterwards, luckily no data loss when I locked the core again.  Have you made any hardware changes recently?

    The size of the cache drive limits how much data you can copy to the array before you need to invoke the mover script or lose the speed bonus.  It all depends on what your keeping on your unraid and how often you add data.

    I have my shares mapped as network drives in windows, I assume most people do.  To see them type \\TOWER into windows explorer adn the shares should be visable.  Then you can move all your data to the shares like you would between harddrives. To do this in linux I think you need to mount the shares but you'll have to find someone with a bit more knowledge than me for that.

    Sync Errors

    I recently upgraded a couple of drives in my array, one data and the parity.  Now after the data drive had been rebuilt the parity check reported no errors.  Shut down and swapped out my parity for a larger drive and rebuilt again.  Check parity again and this time get lots of sync errors.  My first thought was a faulty drive so I swapped my parity back again to a known good drive.  I assumed the sync errors woud go away after a couple of checks but they are still happening.  It seems odd that the errors are always 1/4 of the array but I cant find out where they are coming from.

    I'm only using 3 drives (1TB Seagate, Samsung, Hitatchi) with 4.7.  he array has mostly video files which are all playing correctly so I am assuming the data drives to be good and the parity being calculated incorrectly.  

    Has anyone else had this sort of error? or know how to stop it?

    [FIXED] Unable to boot with hdd installed

    in General Support (V5 and Older)

    Ive been using the free version of unraid for a few months now and so far I have been really impressed, enough to buy the plus licence.  In preperation for the additional drives I installed a 3 in 2 hard drive caddie, http://www.scan.co.uk/products/icy-dock-mb973sp-b-sataiii-6gb-s-sata-backplane-up-to-3-drives  that I had from an old pc.

    Now, when I reboot my unraid server the motherboard doesnt recognise the flash drive and I just get a black screen.  If I switch off power to the hard drives it boots fine.  Now initially I thought the bios had the boot priority wrong but booting to any hard drive is disabled.  I've now offically run out of ideas.

    I'm using Asus M4A78LT-M motherboard with an AMD Sephron cpu.

    Any idea how to solve this issue?
