Usage and Quota Controls

Capacity to Inode Ratio

Ratio: 1TB quota to 10,000 inodes

An inode is a record that describes a file, directory, or link. To ensure good streaming performance of the tape archive subsystem and increased performance for file recovery, this ratio is enforced for all projects.

Checking Quota Usage

Versity’s ScoutFS/ScoutAM product can implement quotas on a user, group, or directory basis. Granite leverages the directory quota feature to limit the size and number of files in an allocation to that allocation’s respective limit.

To retrieve your current quota utilization on Granite you can SSH to: $your_ncsa_username@storagequota.ncsa.illinois.edu. After successfully authenticating it will print out your quota information for NCSA Taiga and Granite global file systems and then exit. An example output is below:

[you@your_host ~]$ ssh [email protected]
([email protected]) Password:
([email protected]) Duo two-factor login for your_ncsa_username

Enter a passcode or select one of the following options:

 1. Duo Push to XXX-XXX-1234

Passcode or option (1-1): 1
Success. Logging you in...
