Your user volume has limited quota associated with it. The default is currently 5 GB, but you can add to that by taking classes that ask for additional quota for their students, or by getting additional disk space sponsored.
To see how much quota you have, type:
check-stanford-afs-quota
the line for AFS tells you how much space you have available in your user volume. If you use a UNIX mail client like Alpine or Mutt to download your mail to your home directory in AFS, any used space that shows up under "Mail", you'll eventually download to AFS.
If you are over quota (or if you have insufficient quota to download your new mail), you will need to clean up your account by deleting old files that you don't need any more. If you need help with this, please submit a HelpSU request.
If you are getting error messages indicating that files can't be written and check-stanford-afs-quota shows that the sum of your incoming mail and the disk space you're actually using is still less than your existing quota, then you should check to see if maybe your AFS server's partition is full (this is highly unlikely). To check, type this command at the system prompt:
fs listquota <path to home directory>
If you are logged into a FarmShare machine, you can use the shorthand symbol ~ (tilde) as your path-to-home-directory. ~ is a special symbol which stands for your home directory.
The output from this command will display your quota allocation and usage in a more cryptic form than that displayed by check-stanford-afs-quota. But the last column contains a percentage-full number for your partition. If that number is extremely large (very high 90s) AND there is a warning flag displayed next to it, submit a HelpSU request, saying it looks like the partition your account is on is full and that it is interfering with your work.
