Check the quota usage in the NetBackup web UI, on the Disk storage page in the Universal shares tab. The column Quota used shows the current quota usage.

Run the df command with the mount point or drive property if it's an SMB share mounted on windows.

Example:

# df -h /mnt/vpfs_shares/test/test
Filesystem Size  Used Avail Use% Mounted on
vpfsd      2.0T  1.9G  2.0T   1% /mnt/vpfs_shares/test/test

Use the command vpfs_quota to query the quota usage. The command should be run on the workload computer if it's a universal share accelerator. The output comes from the command vpfs_quota and may not be the same as in the web UI.

vpfs_quota
Usage:
