A way to see what drives are being accessed throughout the day

flixxx · December 19, 2011

Hello,

is there a log file, script or something i can run to see what disks are being accessed?

I have a specific setup that only 1 disk should be use by my torrents. The other disks have old content and will only spin up if i need to access that content.

I find it often that a few drives spinup when i try to access a video or just randomly throughout the day.

Spinup groups are disabled

Cache_dirs is enabled and running.

So, i want to see on a typical day what directories/drives are being accessed so i can address it.

Is there anyone that can help me with this?

if you are using user shares, this is bound to happen. When you go over a certain amount of files, some have to be dropped. Although cache dirs helps, it doesn't help enough when you have many small files.

When you access a user share, other drives may spin up as they are checked for matching directories.

Thank you,

how can i check what directories are being cached by cache_dirs?

Also, i would still like to know which ones get checked when i know nothing is using the server. I'll then optimize cache_dirs to focus on those folders only.

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.

type control-C when done.
