Quotas

Quotas are enforced on the BisonNet storage system in order to decrease the likelihood that one user could fill up the storage system and prevent other users from using the environment. Most users only have one quota, which is the amount of data stored in their BisonNet home directory. The default quota for users is 100GB. Please let us know if you need additional space by emailing your request and approximate storage needs to bisonnet@bucknell.edu.

To view your home directory quota and usage, run the command:

quota -vs

Example output:

Disk quotas for user abc123 (uid 999999):
Filesystem   space   quota    limit   grace   files   quota   limit   grace
bnspace.bucknell.edu:/home
            18246M    450G     500G            130k   4295m   4295m

This example indicates that the user has a quota limit of 500GB (450GB is a soft limit) and is currently using 18,246MB (about 18.2GB).

Some users also have a scratch directory, which has a separate quota. Here’s an example with an scratch quota:

Disk quotas for user abc123 (uid 999999):
Filesystem   space   quota    limit   grace   files   quota   limit   grace     
bnspace.bucknell.edu:/home
            18246M    450G     500G            130k   4295m   4295m
bnspace.bucknell.edu:/scratch
             8262M  92160M     100G               2   4295m   4295m

In addition, for those that have a shared data directory in /data, quotas are enforced on those directories as well. Those can be checked with the command:

df -h /data/projectname

Filesystem                  Size  Used Avail Use% Mounted on
bnspace.bucknell.edu:/data  1.0T  580G  445G  57% /data

This shows that 580GB of the 1TB (1024GB) is used.
