====== Quota ======
===== Why is there a quota? =====
The quota exists only to protect the server, not hinder you in your work. You can always request more. Don't be surprised if we ask why you need it, this isn't intended to give us a reason to say no, just to make sure you don't go doing anything silly. For example, running VM inside your home directory.

If the request is very large we will usually try to accommodate you in some other manner. It helps a lot if you can tell us your goals, so we may help you achieve them.

===== Check your quota =====
To check your quota use the command 'csquota' which is just a wrapper script around 'quota' (because bugs). 
You should see something like this:
<code>
user@computer:~$ csquota
Filesystem                                  space   quota  limit  grace
server.cs.uchicago.edu:/export/homes/user    918M   2000M  2500M  15296
</code>

^ space | denotes how much space you are currently using. |
^ quota | The maximum amount of disk usage a quota user has. |
^ limit | Hard limit works only when grace period is set. It specifies the absolute limit on the disk usage, which a quota user can't go beyond his hard limit. |
^ grace | The time limit before the soft limit is enforced. |


===== Ok my quota is full. How do figure out what is using all the disk space =====
The command ''%%du%%''. Move along.

^ du -csh | Calculate file and directory usage. (**c**) Show total ; (**s**) recurses down to calculate, but only shows total for input arguments(files or directories) ; (**h**) human readable file size; |
^ $HOME/* | All files, no dot files |
^ $HOME/.??* | All files that start with a dot(.) and have at least two characters |
^ sort -h | sort the input by human readable file size |
^ tail | Only show me the last 10 lines |


===== Networked vs Local Storage =====
If you are working with larger datasets we do not recommend you store these in your home directory. Please create yourself a folder in /local on whatever machine you have access to and put your data there.

Generally, your home directory is not going to be great to use for any heavy read and write application. 

    $ mkdir /local/$USER
