Yea I'm with WeeboTech. Many people have been fixing the issue with mem=4095. I will say it's okay for 5.0 final..

It seems to be memory related for sure though. Some of us here have been able to fix this problem with lowering the ram. (Like I did). Maybe it's not specific to 4GB, but this seems to fix some issue Also, i don't think it's specific to X9 Boards, because I have a different MB and have the same problem.

As Helmonder mentioned, it would be good to mention where to set this parameter for unRAID. Also mention that this means forcing unRAID to use only 4GB of how much ram users have. and for 5.0 final, it would be good to add this in, and include in the release note that unRAID only support up to 4GB of RAM and it will only use 4GB max no matter how much ram the user has. if this is actually the problem, that is.

I'm having this issue and look at my rig.. lol I'm going to guess that it's due to large amount of ram allocated to unRAID. I switched back to 4GB from 16GB and having no problem with writing.. without setting highmem_is_dirtyable To replicate this issue, set highmem_is_dirtyable back to 0 if you have it set at 1. "sysctl vm.highmem_is_dirtyable=0" and copy a huge file (5 - 10GB) through the network. Copying files less than 5GB may seem to work correctly.. Well that's what happened to me at least.

16GB was just really cheap.. lol that was the only reason for me. I switched back to 4gb and seems to be okay now. I will update my sig later with the detail

Not sure if this helps.. but I just downgraded my ram from 16GB to 4GB and I am getting solid write speed of 15 - 30 MB/s for files. no crapping out or nothing. but I also know my 16GB don't have any problem because it ran memtest for few days without any errors... My MB doesn't have this option.. My board is ECS H61H2-M2.. I don't think anyone here uses this board lol

I live in the U.S... and I am looking to buy a M1015 card. Let me know if anyone has one for sale. Thanks.

I have a similar problem. I don't think the server actually crashes, but it sometimes becomes unresponsive during a big file copy and gives me an error that the file transfer cannot be completed. When it cancels, I can access it normally again. This started happening when i upgraded 4GB ram to 16GB ram i think.. maybe i should switch back to 4gb and test it I lose access to the web console...it never comes back. Maybe I should pull one of the 8GB DIMMs. actually.. if it becomes unresponsive, look at this thread: http://lime-technology.com/forum/index.php?topic=23124.msg212864 Do you get errors like this in your syslog? After I upgraded my ram to 16GB, mine too became unresponsive when i was copying a big file and saw bunch of errors in syslog. setting min_free_kbytes value to 65536 helped me...

Same result for me. not seeing any difference.. and uname -a shows 3.4.25-unRAID

oh.. yea you have to assign the right drive for the parity drive, and the right drive for the cache.. other drives shouldn't really matter.. hopefully someone will be able to help you better than me.

Do we test this with "sysctl vm.highmem_is_dirtyable=1" or no?

Pretty sure you're not screwed. This is normal behavior when 'new config' was clicked. or 'initconfig' was run. I think all you need to do is reassign them and start the array. at least this is my understanding. don't do anything yet until someone else confirms this. i know you're probably freaking out now so i thought i'd comment something real quick lol

Yea. I figured it doesn't support. probably will get extreme4

You are always going to see "burst-like" behavior on the network if the sink is slower than the source (which is the case most of the time in unRaid). I see.. well not too big of a deal then.. But the problem is still there without setting "vm.highmem_is_dirtyable=1" for me.. oh well im gonna change the board soon so maybe that'll change who knows. thanks for all the work you do

I really don't need it to be anything over 20MB /s since I don't usually upload anything to unraid too much. I just want a constant solid write speed. Honestly, it's not a HUGE problem for me, but I heard the new rc9a was supposed to fix this issue in a way... and I just wanted to mention doesn't seem to be fixed --- EDIT i just realized.. most of you have X9SCM-F I just have some cheap board with Celeron G530. but I guess what I want to say is that we all have this similar issue where high speed is kind of 'burst like'. It wasn't too slow when I only had 4GB ram though. Maybe i should just switch back to 4GB ram. idk.

Here is the problem I'm having with "vm.highmem_is_dirtyable" variable. When I first boot up the machine, without setting "vm.highmem_is_dirtyable=1", I get less than 1 MB/s for the write speed. After I set vm.highmem_is_dirtyable=1, I get the speed close to 100MB/s sometimes. HOWEVER, this ONLY lasts about 500 - 600 MB. I don't know if anyone has tested with larger files (6 - 10 GB) file, but after awhile it goes down to below 1MB/s again. AND, sometimes it won't even let me write anything. It will have some kind of error. Don't have the error handy, but it was something about the network drive is inaccessible or something like that. When I tested with some 10GB file, it failed after copying about 70%. Not all the time though. Maybe half of the time i tested. Then I set "vm.highmem_is_dirtyable" back to 0, then I get about 5 - 15MB/s. I have 16GB ram.

I don't know anything about IOMMU .. Is that needed for esxi to work or is that needed for unraid to work on esxi?

I'm interested in doing this for myself.. I have a spare processor (1090T) to use, so all I need is a motherboard. I hope someone can answer some of my question.. is ASRock 970 EXTREME4 really best one out there to do this? Do you guys recommend any other boards? I have Asus M4A88TD-V EVO/USB3.. I wonder if this will work.. but then kinda dont trust this board. Used to have random freeze once in awhile lol Is there any guide on how to get this to work? I have no idea how to set this up... You guys talk about M1015.. I have AOC-SASLP-MV8. Would this work? Please let me know! Also,

so.. few things that i wanted to say about this.. You say to run 'vboxwebsrv -b -H 127.0.0.1 --logfile /dev/null >/dev/null' to run vbox webservice. However, I think this changed the permission for /dev/null and caused some problems for my other plugin.. so maybe we should try to either run it as nobody or point the log file path to actual path? I have no knowledge about building a linux package what-so-ever, but isn't there a way to set a build number? I am mentioning this because I wasn't able to use 'Upgradepkg' to upgrade from your old build of 4.2.6 for 3.4.11 kernel

got it to work some how.. will post the detail in a bit... ----------EDIT------------ VBoxManage setproperty websrvauthlibrary null Running this, then restarting vboxwebsrv worked so i guess it's something to do with authentication/permission?

I keep getting errors.. It says "An error occurred communicating with your vboxwebsrv. No more requests will be sent by phpVirtualBox until the error is corrected and this page is refreshed. The details of this connection error should be displayed in a subsequent dialog box." Then it tells me "Error logging in to vboxwebsrv." I have vboxwebsrv running as root and have the correct root / password entered in config.php for phpVirtualBox.. anyone having this problem?

This.. looks.. amazing Just what I was looking for. Thank you so much. WIll try it this weekend..

Contact Azza, they sell a replacement side panel without the fan for $25 shipped US Do they do this for all their cases? I have Azza 1000 that I'm planning on using for unraid eventually, but i do not like this 200mm side fan with the window.
