A catalog of JLab-resident, IT-Division-managed disk space. Order is from more temporary to more permanent.
Contents
Scratch Disk: /scratch
general purpose temporary files
- 1.8 TB
- user writable
- available lab-wide
- files deleted after 30 day of non-access
- not backed up
Work Disk: /work/halld
quasi-permanent analysis support space
- 2.6 TB guaranteed, 5.0 TB maximum
- user writable
- available only for Hall D users
- files never deleted by system
- not backed up
Cache Disk: /cache
staging area for tape-resident files
- image of tape library files
- non-user writable (request write from library)
- general cache available for all farm users
- no Hall D dedicated space
- files deleted to make space for more, oldest by access deleted first
- not backed up, yet backed up by construction
Group Disk: /group/halld
permanent storage for experimental groups
- 35 GB (up from 30 GB), controlled by quota
- user-writable
- available only for Hall D users
- files never deleted by system
- backed up
- snapshot'ed
Home Directories: /home
your stuff
- individual disk quotas
- user writable
