Use this form to request an increase in the amount of disk space
you are allowed to have in AFS (the AFS quota). You can also use this
form to request group space or anonymous FTP space.
You may find the information in the
SLAC AFS Users' Guide
useful in managing your space, and the information in the
UNIX Disk Space web page useful in
determining the type of space you need.
You will also need to collect
some information before starting:
- The current AFS quota. Go to the directory (your AFS home
directory if you are requesting an increase in your personal quota)
and enter the command
fs listquota
and note
the amount under 'Quota'. This number is in kilobytes; divide by 1000
to get megabytes.
- Decide whether you need an increase in the quota of an existing
volume, or a new subvolume. If this is a new project, a new volume
with its own quota may be most appropriate. SCS recommends that most
volumes should be kept to no more than about 500MB and strongly
discourages volumes greater than 1GB(1).
We also discourage allocations of more than a few gigabytes in total
for a user's home directory since that is usually an indication
that the space would be better allocated in group space.
- Your estimate of how much more disk space you need.
- If you want a new volume, specify a new subdirectory
of your directory that will become the mount point of a new AFS
'volume' (but don't create this directory yourself -- an AFS volume
cannot be mounted on top of an existing directory).
This volume will have its own quota, but otherwise will look like a normal
subdirectory. You might also want to do this if you do not want the
space needs of a project filling up your top level home directory and
possibly interfering with functions such as reading mail.
For more complicated requests, use the 'Additional Instructions' field
below to write to us. For large projects, software package
installations, group space, or situations where you know the disk
space needs are going to grow substantially over time, please let us
know of your plans in the "Planning Information" field. This helps us
allocate the right kind of disk space for your needs, and helps us
plan for future acquisitions of disk space.
Examples:
- User smith finds from the fs listquota command that he has
a current quota of 100 MB and is using 80 MB. He needs 40 MB to build a
new program and have a comfortable amount of space to work. He requests
a new quota of 120 MB. Please note that the figure you enter in the
"New Quota requested" box should be the total quota you expect to have
for "Mountpoint" after this request is processed.
- User jones finds from the fs listquota command that she has
a current quota of 160 MB and is using 150 MB. She needs 100 MB free for
a large project. She requests 100 MB in a volume to be named simulation.
Her home directory will remain unchanged, and she will have a new subdirectory
named ~jones/simulation that will have an independent quota of
100 MB.
- User higgs would like to make some files available to the world
via anonymous FTP. He checks
'Anonymous FTP - outgoing' in the form, and enters '5' in the quota
requested for that directory. The default directory name of
/afs/slac.stanford.edu/public/users/higgs will be assigned.
- User Benton needs a directory for a new experimental group to
store source code. She checks 'Group Directory' in the form, enters
'50' in the quota field, and puts the group name 'neutrino' in the
mount point (subdirectory) field. The directory created will be named
/afs/slac.stanford.edu/g/neutrino (/afs/slac.stanford.edu/g is where
all group directories live).
