Posted April 7, 20214 yr Sending a disk to sleep is easy: mdcmd spindown 0 mdcmd spindown 1 ... I tried to reverse engineer the icon click, but was not successful. As an example. Clicking the icon calls "http://tower/webGui/include/ToggleState.php" with the following POST content: device=Device&name=cache&action=down&state=STARTED&csrf=blabla&csrf_token=blabla As "device" has been set to "Device" it calls this line in "ToggleState.php": if ($name) emhttpd("cmdSpin$action=$name"); else emhttpd("cmdSpin{$device}All=true"); Which executes curl: $ch = curl_init("http://127.0.0.1/update.htm?$cmd&startState=$state&csrf_token=$csrf"); curl_setopt_array($ch, [CURLOPT_UNIX_SOCKET_PATH => '/var/run/emhttpd.socket', CURLOPT_RETURNTRANSFER => true]); curl_exec($ch); The update.htm part confuses me as a static HTML page is not able to execute anything. Maybe this is rewritten through the NGINX webserver?! Whatever... I tried to find the "cmdSpin" string in the Unraid Source Code and was only successful in the unassigned devices plugin: function spin_disk($down, $dev) { if ($down) { exec("/usr/local/sbin/emcmd cmdSpindown=$dev"); } else { exec("/usr/local/sbin/emcmd cmdSpinup=$dev"); } } EDIT: Ok. This command works: /usr/local/sbin/emcmd cmdSpindown=cache Why isn't this mentioned anywhere? ^^
July 15, 20223 yr Simple Question: Is the labeling cache in the command to spindown every drive that is used as cache or should I adjust it per drive label ? Example: I have a cache drive explicitly for docker labeled "vmdockercache" Thanks.
