For anyone who is interested I re-wrote the fan speed control script as an UnRaid v5 plugin (attached). Make it easier to play with the variables. fan_speed-1_0-noarch-1ds.txt

I saw the same issue. I just stopped trying to "stop" the fan. By setting my lower boundary to the PWM value that takes me to my lowest fan speed (700 rpm) the behavior stopped.

Seems there may be an issue with going to sleep (which worked well on 12b): Snip from my log: Nov 6 22:01:26 Tower kernel: PM: Syncing filesystems ... done.

for the price of a drive cage you can buy a spare drive in case of failure, or just more capacity. I think drive cages are overrated. Having said that - the first unraid I built I used drive cages because I thought they were cool. Don't need a cage if you only swap a drive once or twice a year is what I discovered - oh and extra problems with the cages due to more points of failure. The fans in my cages started dying.

I have a very basic Supermicro X7SPE-HF-525 with 4 Hitachi 2gb coolspins and everthing is working well. First time using AFP as well - created a TimeMachine user share, turned on AFP and enabled AFP on the share and disabled SMB and my Lion machine can see it, created the sparsebundle and is backing up now. So from a "nothing fancy" user things look great. I chose these components to avoid realtek NICs (hate them) and high compatibility. Just adding this so people don't get too scared of trying beta 13 (even if you are superstitious)

Thanks Aiden - didn't mean to call you out on the 5 beta stuff. I have an even newer version of the script I should post. I also wrote a 5 beta plugin to learn about plugins hoping we get a "release candidate" of 5 soon but that's a whole different subject. One thing I will say is thanks to the starter of this thread and all the contributors - I built a box using the case recommended here, an X7SPE-HF-525 board, and 4 Hitatchi 2Tb Coolspin drives and I couldn't be happier. It's quiet, cool, performs great, looks cool and IPMI is really, really great. Thanks for the thread!

The best all around solution would be: Tom takes "Simple Features" and makes it the stock, default UnRaid GUI - it looks WAY BETTER than the current stock GUI The rest of us get busy writing V5 plugins that work and look great with the new "stock" GUI The UI is "skinnable" in a way that does not affect the plugins - meaning that plugin development and UI development can proceed independently and people can develop new "looks" for UnRaid the do not affect plugin code. That would be nivana... Having used the Simple Features GUI I really can't go back to the stock version - thus any plugins I create will go towards Simple Features. Sorry - that is the way it is. People will vote with their time and spent it improving things they like to use.

This was helpful - it worked. Thanks!

If you are using a cache drive does 5b12a ever spin it down? Mine seems to stay spinning unless I manually spin it down from the GUI.

Welcome back speeding-ant!

bonienl - exactly what I thought you'd say. Just thought I'd express my preferences.

One more thing... bonienl - sorry I really liked speeding_ant's orginal "clean" header. It completed the design beautifully. Adding back the mountains, snow, etc. - is that really necessary? Don't get me wrong the extensions you are doing from a functionality standpoint are amazing but speeding_ant knocked it out of the park with the original UI. Your changes to make it look more like the original v5 GUI are going backwards IMHO.

Regarding the "UI" + "Plugins" vs. "All in One Release" debate: I feel I need to be "the other side of the coin". I am a former UnRaid user from way back (I registered on the forums in 2006 ), who left for a while, and just returned to using UnRaid. I have literally spent hours and hours reading the forums to determine all I really want is: A really nice GUI - LOVE this GUI! Sorry Tom, you are not a GUI person: the stock UI with 5 is terrible (I actually think 5 is worse than 4) Sleep - please sleep my server when I'm not using it Cache Dirs - This is really useful Check parity monthly Send me email if there are any problems - set it and forget it. Does anyone have any idea how long it takes to educate yourself on the forums - find this stuff and then try to make it work on V5? I'll give you a hint - sleep is completely different on V5 from V4 - all the sleep scripts you will find on the forums don't work! So, I for one, LOVE the idea of dropping in one package, and get working versions of this stuff AND a GREAT new GUI on ONE STEP! Go Speeding_Ant and Bonienl!!!!

Nothing is ever as simple as it sounds. I built this machine based on Starcat's tout of the perfect server where everything "just works". Then I asked specifically: "For the folks who are actually using the HW defined: X7SPA-HF and Fractal Array case. Are you running UnRaid 4.7 or one of the new 5 betas? Will the scripts in this thread work the same on both releases? I am planning building this exact system and am thinking about starting right off on the latest 5 beta. Cheers!" It turns out nothing really works on 5b12a - it is a PITA to get the fan control to work and sleep is handled by a completely different command. So here are my tips - first the sleep script is easy. You only need to change one line: # Go to sleep # echo 3 > /proc/acpi/sleep # Above deprecated on UnRaid 5 and above # To go to sleep use this instead -> echo -n mem >/sys/power/state Fan speed control is simply a non-starter unless you modprobe the correct drivers first. Here is my code below: #----------------------------- #----- Enable Fan Speed ------ #----------------------------- echo "Starting Fan Script" # Adapter drivers modprobe ipmi-si # If you have IPMI # Chip drivers modprobe coretemp modprobe w83627ehf chmod +x /boot/scripts/unraid_fan_speed.sh crontab -l >/tmp/crontab grep -q "unraid_fan_speed.sh" /tmp/crontab 1>/dev/null 2>&1 if [ "$?" = "1" ] then crontab -l | egrep -v "control unRAID fan speed based on temperature:|unraid-fan-speed.sh" >/tmp/crontab echo "#" >>/tmp/crontab echo "# control unRAID fan speed based on temperature" >>/tmp/crontab echo "*/2 * * * * /boot/scripts/unraid_fan_speed.sh 1>/dev/null 2>&1" >>/tmp/crontab cp /tmp/crontab /var/spool/cron/crontabs/root- crontab /tmp/crontab fi Make sure you edit the fan speed script to match your HW configuration - see my previous post. Cheers!

Rognom: First this section has to be accurate to what is installed on your system: ### VARIABLES FOR USER TO SET ### # Amount of drives in the array. Make sure it matches the amount you filled out below. NUM_OF_DRIVES=3 # unRAID drives that are in the array/backplane of the fan we need to control HD[1]=/dev/sda HD[2]=/dev/sdb HD[3]=/dev/sdc #HD[4]=/dev/sdd #HD[5]=/dev/sde #HD[6]=/dev/sdf If it is not you will certainly get errors like what you are seeing. You can see what the "sdx" values should be on your UnRaid "Main" page. Second this also has to match your system: # Fan device. Depends on your system. pwmconfig can help with finding this out. # pwm1 is usually the cpu fan. You can "cat /sys/class/hwmon/hwmon0/device/fan1_input" # or fan2_input and so on to see the current rpm of the fan. If 0 then fan is off or # there is no fan connected or motherboard can't read rpm of fan. ARRAY_FAN=/sys/class/hwmon/hwmon1/device/pwm4 ARRAY_FAN_INPUT=/sys/class/hwmon/hwmon1/device/fan4_input # Used to track actual rpm values The way you find these values is "pwmconfig" as indicated in the code above. Here is what mine looked like: Testing pwm control hwmon1/device/pwm4 ... hwmon1/device/fan4_input ... speed was 1442 now 706 It appears that fan hwmon1/device/fan4_input is controlled by pwm hwmon1/device/pwm4 So I adjusted the code above to match. BOOM! Works.

If you edited the script in any windows editor you may have introduced errors in the line feeds. Try this: Open a telnet session to your server and use the command "mc" to browse through your directory structure. Go to the location of your script and press "F4" to edit it. Press "F12" and choose "Linux Format (LF)". File is saved now in the correct format.

Great Rognom - given you have gotten this far I'm sure we can get it figured out. I will work on it tonight when I get home and let you know if I can get it going.

root@Tower:~# sensors No sensors found! Make sure you loaded all the kernel drivers you need. Try sensors-detect to find out which these are. root@Tower:~# sensors-detect -bash: /usr/sbin/sensors-detect: /usr/bin/perl: bad interpreter: No such file or directory root@Tower:~#

I should add that I am using the X7SPE-HF-D525 version of this board, not the X7SPA-HF. I also have the latest BIOS loaded which seems to manage the fan itself - there does not seem to be a way of turning off BIOS control so I have it 100% at the moment.

# enable fan speed control cp /boot/config/sensors3.conf /etc/ /usr/bin/sensors -s In the original post [#1] it just said run this script from crontab. Here there seems to be some sensors config needed? I ran "sensors" and the response I get is "no sensors found!" I am running 5b12a. Can someone point me in the right direction please? Thanks, Dan

Awesome - thanks Aiden that is the encouragement I was looking for.

Just asking this question one more time - is anyone running 5b12a on this platform? If so, any issues? I am building a brand new array and trying to decide if I start with 4.7 or jump straight to the 5b12a version.

WeeboTech - is this on the server in your signature (8gb RAM)? Anyone have recommended setting for 6 disks. 4gb RAM?

The case is awesome and it will easily fit the larger "E" version boards if you want to that route. If I knew that i'd have used the E 525 version. Oh well...
