My parity drive is constantly "spun up"

 

So i'm trying to diagnose what it is the culprit. I use a cache drive and a cache only share for my apps, so i hope it's not those. The rest is then files simple stored on it and should only be written to the array once, when the file mover kicks in.

 

is there an lsof for parity? for open files, or is there something better i can use?

 

searching the forums i see Joe's post but it's a year old, is this still relevant? do i need to use an updated version of inotifywait?:

 

Install inotify tools ( inotifywatch/inotifywait.) this can be done through unMENU, or you can log in on the command line and type:

mkdir -p /boot/packages

cd /boot/packages

wget    http://www.slackware.org.il/slackware/slackware-12.2/slackware/a/inotify-tools-3.13-i486-1.tgz

installpkg inotify-tools-3.13-i486-1.tgz

 

If you have a lot of files on the drive, you'll want to increase the max number monitored by typing something like this:

echo "100000" >/proc/sys/fs/inotify/max_user_watches

 

  Then invoke it as follows:

inotifywait -mr /mnt/user/Movies

(where "Movies" is the name of your user-share)

then, just watch what is accessed.

Joe may jump in and correct this, but I do not think lsof will help, since it monitors what's written to the file system; and no files are actually written to it.

 

Are you SURE it's always spun up?  This could be a display issue => are both UnRAID's Web GUI and UnMenu (assuming you have it installed -- install it if now !!)  showing it still spun up?    You can always hold your hand on the drive to confirm it's running (you'll feel a SMALL vibration).

 

Double-check your spindown settings to confirm this isn't just a simple settings problem.

 

thanks for reply,

 

well i've narrowed it down to utorrent by disabling the plugin and forcing a spin down.

 

Previously is i forced a spin down, parity would start up within seconds....so i'm on the right track at least

Sounds like you've found the culprit.  It can't write directly to the parity drive;  but if it does ANY writes (e.g. even if it isn't changing data, but just re-writing a folder name or some such) to ANY disk it will, of course, cause parity to spin up.

 

well it seems that it's any active torrent that is seeding. This doesn't happen in transmission.

 

utserver must be writing something, which is a shame. + i'm sure it never use to be like this!

 

does anyone else have utorrent successfully seeding and having parity spun down? maybe it's the way i have it configured. I use a cache share called torrents to do the heavy writing whilst downloading and then the mover runs to put it on the array. is this wrong?

 

i suppose this can be moved to plugins forums

I'd suggest you start a thread in the plug-ins forums with a title that will catch the attention of a utserver expert.    It does sound like it's likely just a configuration issue.
