Disk quota defines the maximum amount of hard disk space allowed for a user's files in his home directory. The user is given 200 MB quota space on SKEW4 when the account is created.
Check Quota and Usage
You can use "quota -v" command to check the quota allocated and usage of space in your home directory.
The quota monitoring system reports both the disk space and the number of files created. The first few columns report usage of disk space used while the rest report the number of files in your home directory. For now you can simply ignore the last four columns - all the columns starting and to the left of column "files".
Over The Quota
The first time you exceed your soft limit, you will get a warning message like the one generated in the example below, where a file is being copied:
This will prevent many processes like SAS, MATLAB or FORTRAN to run from your home directory though some other activities, like modify, copy and save files are still allowed, but only for a grace period of 7 days. If your disk usage is over your soft limit, then the timeleft column will tell you how much grace time is left.
The hard limit cannot be exceeded at all; you will no longer be able to save/modify/copy any file in your home directory. In some cases, reaching your hard limit can prevent you from logging in.
If you ever hit the hard limit when you try to save some files, please save the file to scratch space first. Make some space in your home direcory as described in the next section. Then copy the file over from scratch.
Getting the quota below its limit
To get your disk usage back below your soft limit, you can do one or more of the following:
Be careful only to delete files that you are absolutely sure you do not want, as you may not be able to get them back (see skew backup if you do make a terrible mistake and delete something important).
