April 2, 201214 yr i install almost every plugin(for evaluation). now i cant spin down my drives. i have parity, cache and disk1. there is no ssd. all hdd. the purpose of hdd cache drive instead of ssd is the cache drive can quickly be use as backup array drive when one of my array drive died. i tried disable all application and services that i can in unraid main menu/settings. im aware that some application installed with unmenu package manager have to be manually stop. i believe, i cant spin down drive because there are some application that uses the drive. how can i spin down all drives while maintaining all application/services active(assuming the services/application are idle and no one is accesing the drives)? possible solution that i can think of 1. add new cheap usb flash drive to the unraid. 2. install all application to the falsh drive. 3. although flash drive with consistent writing is short lived, 8gb flash drive is extremely cheap nowadays. if settings data in the flash drive is important, ill just back it up. maybe set up cron job. what do you think. are there other elegant solution?
April 3, 201214 yr Enter lsof to see what is keeping the drive busy. Install notify is needed: http://lime-technology.com/forum/index.php?topic=17449.msg157730#msg157730
April 3, 201214 yr Author thanks. tried that. i see a lot of access from my drives. im planning on modifying the plg files to 1. install application to ramdrive(since unraid is installed in ram, i figure, my apps should also install to ram) 2. all app use flash drive for storing settings 3. all app use cache drive for downloading files(torrent, pyload etc) since my linux is a bit rusty and i have zero experience with slackware before, what do you guys think of this? is it possible? is it recommended? what do you guys do to for your drive to spin down?
April 3, 201214 yr Yes, it's possible given enough ram. Personally, I just leave the cache drive spinning. To me, It's not worth the effort to save the 15 cents for every 8 days of the server running or the $7 a year it costs to leave it spinning.
April 3, 201214 yr Author well, the issue is not save the electricity bills. the thing is, by reducing the drive spinning, i can reduce the heat, increase the life of the drives. afterall, one of the killer features of unraid is the ability to spin down drives and prolong the life of drive.
April 4, 201214 yr My cache drive in my ESXi build rus 24/7/365. My CrashPlan backup server runs 24/7/365 and the drives in that guy rarely have a chance to spin down as backups are almost always coming in from one place or the other.
April 4, 201214 yr Author here are my inotify log(only unique lines, alphabetically sorted). i have all service running. but havent uses any. plus, i havent put my data on unraid. in summary, services that uses disk 1 and constantly spin up parity drive are 1. crashplan 2. dropbox 3. mysql 4. slimserver 5. torrent(install transmission) i think it would be efficient if all of these files are in cache drives with dot directory name(.crashplan, .dropbox etc). data files are in normal directory names. after much thinking, maybe i use cache drive and be done with it. one drive spinning is better than 3 drive spinning all the time(cache + disk1 + parity). i cant even mount my flashdrive using snap. except for transmission, every services are install through plg files. thanks. inotify.rar.txt
April 4, 201214 yr At least you identified why your disks are constantly spinning. You are right, if you put all the applications on a single disk (most use the cache drive) it will be the only one accessed.

April 5, 201214 yr Author can i redirect program install dir to /usr/local/ directory? this is located in system ram, correct? any changes made in this directory is lost once the system reboots right? im planning to put install dir in /usr/local/ folder and data/setting to be put in /mnt/cache/. what is install dir? is it program binaries or program settings? how do i know if an application stores its settings in its folder or not? im trying to figure out whether crashplan, dropbox, mysql and logitech media server can be put to system ram. i have 8gb of ram with plenty of unused space. thanks.
April 6, 201214 yr Author sucessfully install everything on cache drive. now disk1 and parity spun down. planning to install everything on extra flashdrive, bu somehow cant mount it using snap. plus, when boot, is snap loaded first or snap loaded based on alphabetic queue? i asked this because, if snap is not loaded before application is running, the application cannot run and i have to manually execute the application everytime i reboot. by the way, i noticed that, if my internet is down, boot time is extremely long. it is as unraid download everything everytime the server boots. how to overcome this?
September 4, 201213 yr Hard disk Spin down on My Qnap TS101 running 6.5 does not work due to lack of memory.Sorry mate - I gave up with 6.5.1 - could not get it to spin down at all.
