There are two main filesystems on Pegasus. The first is connected over NFS and used to store
/$SCHOOL/groups , and has 2Pb of usable space. The second is a high-speed Lustre scratch filesystem, accessed as
/lustre which has 2Pb of usable space. Note that neither are meant for long-term storage.
By default, you have access to three locations:
/$SCHOOL/home/$netID- your home directory. NOTE no jobs should be run against the
/$SCHOOL/homepartition, it is not designed for performance. Use
/$SCHOOL/groups/$group- shared group space, accessible by anyone in your group. (If you are unsure of what group you are in, the groups command will tell you.) NOTE: no jobs should be run against the
/$SCHOOL/groups/$grouppartition, it is not designed for performance. Use /lustre instead.
/lustre/groups/$group- shared group scratch space
Currently, quotas are only in place at the school (
/$SCHOOL/) level but individual user and group quotas will be implemented at a later time. More information about this will be posted as it becomes available.
Warning: Backups are your responsibility. We cannot recover accidentally deleted files from any filesystem in Pegasus. Also note, neither filesystem is meant for long-term storage and is subject to requests of removal by support staff. We recommend storing your source codes on Github.
