The department filesystem is centered around the concept of
/ (called "root") from our Linux filesystem. Some of the important volumes in our filesystem are listed below. Volumes which are "shared" accessible to all department workstations. Non-shared volumes are specific to an individual machine. Shares marked "SMB" can be accessed as remote volumes on personal and research machines.
|/admin||Files to assist in the administration of departmental programs and organizations||Yes||Yes||Snapshots|
|/contrib||Unsupported, user-provided software||Yes||No||Snapshots|
|/course||Directories for courses and course projects||Yes||Yes||Snapshots|
|/data||Large datasets with lesser backup needs||Yes||Yes||Daily|
|/home||User home directories||Yes||Yes||Snapshots|
|/local||Tstaff-managed software and configuration specific to Brown CS||Yes||No||Snapshots|
|/ltmp||Local, non-networked scratch space that is not backed up. Available only on Linux. Should only be used for large-scale temporary storage when reliability is not important.||No||No||None|
|/nbu||Networked scratch space that is not backed up||Yes||Yes||None|
|/research||Space for research projects and groups||Yes||Yes||Snapshots|
|/sysvol||Files for various departmental system services||Yes||No||Varies|
|/web||Files for departmental websites||Yes||Yes||Snapshots|
Remote Access To The Filesystem
Users can access their home directory through the ssh gateway using scp or through the CS VPN using the SMB protocol. See the Remote filesystem access page.
All users are given personal directories in
/nbu/people/username. All users have a personal web directory in
Undergraduates are given space in
/home only. Additional space will be granted only for pursuit of course goals or faculty-sponsored research.
This is the highest level of backup which tstaff offers. In addition to nightly backups, snapshots are taken every four hours. Every directory on a volume with snapshots has a hidden
.snapshots directory which you can use to access the snapshots. Visit the snapshots page for more information.
These volumes are backed up nightly, as described on the backups page. There are no snapshots.
These volumes are never backed up.
research have quotas attached to them. Undergraduates' home directories have a quota of 500M. All other directories have quotas representing their maximum expected usage, which can be increased upon request by emailing email@example.com.
The /local/bin/gpfs-usage command will let you know what percentage of your quota you are using and how much space you have left before hitting your quota.
The following volumes have been deprecated. The directories inside these volumes have been replaced with symbolic links to their new locations in order to maintain compatibility with old scripts and configurations. However, no new directories are being created, and new scripts should not refer to these locations.
|/tierfs||/data (tier2) and /nbu (tier3)|
