Disk quotas are imposed on all central UNIX systems to divide up the disk
resources fairly, and to protect the systems against runaway programs filling
up the disks and preventing other people from doing their work. The quotas are
flexible and can be changed upon request, especially for special short-term
projects. If the disk quotas seem restrictive, remember that this is guaranteed
disk, backed up nightly, and maintained by full-time staff. The effective cost
is therefore much higher than a disk you can purchase for your own use.
Each user is assigned a disk quota for their shared space (AFS). They may
also be assigned additional space local to particular computers (for data files
or scratch space) or additional AFS volumes for special projects. The command
to check your quota on any system is
quota [directory].
By default, the user's home quota is reported. If a directory is named, the
quota relevant to that directory (if any) is reported. If local disk quotas are
in use on the system, all quotas assigned to the user are reported.
Requesting Additional Disk Space
If you think you are out of disk space, follow the steps below.
- Make sure you are out of disk space by using the quota
command.
- Remove any unnecessary files.
- Compress any unused files; see Compressing a File.
- To request a larger quota for your account, send e-mail to research.computing@dartmouth.edu
requesting an increase on your disk quota.
