Quota bekijken

Your personal quota only determine the amount of disk space your own data may occupy and the number of files and folders/directories you may have on your H:-disk / home directory. Quotas may be active on other disks as well, but 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 H: disk right click on the H: disk, then choose Properties to view the amounts of used and available personal disk space in kbytes.

Unix

On Linux systems use the following command to view the personal quota and current usage:

 quota

On Solaris systems use the command:

 quota -v

Without the -v flag the quota command only reports about file systems where the user is over quota. The command may take a while to complete because it examines all mounted file systems.

The output will show lines like:

Disk quotas for mylogin (uid 207):
Filesystem      usage   quota   limit    timeleft  files  quota  limit    timeleft
/home/mylogin  491585  500000  600000              14901  50000  60000

usage 

The amount of disk space in kbytes currently in use.

quota 

The maximum amount of disk space available for you.

On Unix systems you may exceed your quota temporarily (upto 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 Unix 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.

How to determine what your disk space is used for

On a Unix login server go to your home directory

 cd
 pwd

The pwd command will show something like /home/group/mylogin or /home/mylogin.

Now type the following command:

 du -dsk .??* * | sort -n

This will produce a list of the files and folders in your home directory each preceeded by its size in kbytes, sorted by size.

On a Windows system open/explore your H: disk and examine the disk space used in each folder by right clicking it and selecting Properties.

Mail

The Squirrel webmail service offers a convenient way to view your mail quota and current use. The available disk space and current use are shown at the top of the folder list on the left. The Folder sizes link at the bottom of the folder list produces an overview of the disk usage per folder.
