Article ID: 401
Last updated: 31 Dec, 2025

To find the /nobackup system that is assigned to you, type:

pfe21% ls -ld /nobackup*/your_username

In the following example, the output shows that the /nobackupp17 directory is assigned to user zsmith:

pfe21% ls -ld /nobackup*/zsmith
lrwxrwxrwx 1d root root 19 Dec 23 2024 /nobackup/zsmith -> /nobackupp17/zsmith

For more information about how /nobackup directories are used, see NAS Lustre Filesystems.
