Your personal quota only determine the amount of disk space your own
data may occupy and the number of files and folders you may have on your
Windows U:\ disk or Linux home directory. Quotas may be active on other
disks as well, however not all disks have quotas. The mail servers also use
quotas to limit the disk space of each user’s mailbox.
Windows
On Windows desktops where the home directory is available as U: or H:
disk right click on the disk, then choose Properties to view the
amounts of used and available personal disk space in kbytes.
For a graphical view of your disk usage you can use WinDirStat.
On managed systems this utility is installed at S:\windirstat .
Linux
On Linux systems use one the following two commands to view the personal quota and current usage:
quota
The output will show lines like:
Disk quotas for user login (uid 1000):
Filesystem blocks quota limit grace files quota limit grace
homeX.science.ru.nl:/disk/login
4899120* 4864000 5120000 7days 2880 1900000 2000000
- blocks : The amount of disk space in kKB (kilobytes) currently in
use.
quota : The maximum amount of disk space available for you.
On Linux systems you may exceed your quota temporarily (up to 7 days). For Windows however this is an absolute maximum. - limit : The absolute maximum amount of disk space you can occupy
(see above).
timeleft : The time left to get below your quota.
If you wait too long (i.e. if timeleft shows EXPIRED), you cannot write files (new or old) until you’ve cleaned up to get under quota again. There is a risk of losing data if you try to write when the quota grace period has been exceeded. - files : The number of files currently owned by you.
quota : The maximum number of files and folders you can have.
On Linux systems you may exceed your file quota temporarily (upto 7 days). Again for Windows this is an absolute maximum. - limit : The absolute maximum number of files and folders you can
have.
timeleft : The time left to get below your file quota.
If you wait too long (i.e. if timeleft shows EXPIRED) you cannot create files anymore until you’ve cleaned up to get under quota again.
df
If quota gives no output, you have a homedirectory on ZFS. The ZFS filesystem doesn’t have a
softquota, nor a timeleft concept. To see the size of your homedirectory use df, the output
will look like:
df -h ~
Filesystem Size Used Avail Use% Mounted on
f6ea112e23d448e498d4374805f60174.home.science.ru.nl:/export/mylogin 5.0G 3.6G 1.5G 71% /home/mylogin
How to determine what your disk space is used for
On a Linux login server go to your home directory
cd
pwd
The pwd command will show something like /home/mylogin.
Now type the following command:
du -sh * .??* | sort -h
This will produce a list of the files and folders in your home directory, each preceeded by its size in MB (megabytes), sorted by size.
Another command to sum up disk usage is
ncdu ~
Frequent culprits for eating your quota
In general it is caching, this is semi-useless, because caching is meant to be done on local storage, not your network homedirectory.
Python PIP
In general look here for pip cache commands. TLDR: use pip cache purge to clean up.
Firefox
From the commandline use this command to clean the firefox cache:
rm -rf ~/.cache/mozilla/firefox/*. Then restart firefox.
To reduce the amount of cache size used by firefox, go the the about:config
settings (via the address bar) and search for browser.cache.disk.capacity and
you may want to look at other browser.cache.disk.* settings as well.
Anaconda
The Roundcube webmail service offers a convenient way to view your mail quota and current use. The lower left corner shows the percentage of quota in us. Next to that, clicking Folder options, lists all folders. Clicking on a folder gives the option to Click to get the folder size.
