In addition, you can specify a quota limit for users but allow the users to exceed that quota limit. When you enable quotas
without limiting disk space, you can track disk-space use on a per-user basis without denying users access to a volume when
they exceed that limit. It is also possible to specify whether the system logs an event when a user exceeds the quota warning
level and quota limit.
Enabling, Disabling, or Setting Disk Quotas on a Volume
1. Log in to the NAS Manager.
2. Click Disks.
3. Click Volume Tools.
4. On the Volumes page, click the volume to manage.
5. Click Set Default Quota.
6. On the Default Quota for volume page, click the Use quota limits to manage use of the volume check box.
7. Click the Limit volume usage to check box and enter the volume usage limit.
8. Click OK.
NOTE: Setting a default quota entry for a volume applies the setting to any users (without individual disk
quotas) accessing the volume.
Adding Disk Quota Entries
The Quota Entries page allows you to add, delete, or configure disk quotas for any NAS system user.
When you enable disk quotas for an existing volume, volume usage is automatically tracked for new users from that point
forward. However, existing volume users have no disk quotas applied to them. You can apply disk quotas to existing volume
users by adding new quota entries in the Quota Entries window.
To add a new quota entry, perform the following steps:
1. Log in to the NAS Manager.
2. Click Disks.
3. Click Volume Tools.
4. On the Volumes page, click the volume to manage.
5. Click Set Quota Entries.
6. On the Set User Quotas for Volume page click New Quota Entry.
7. Select a local user from the list box, or type the name of a domain account in the text box (in the format
domain_name\user_name).
8. To allow unlimited disk space usage, click the Do not limit volume usage radio button, and then go to step 10.
Otherwise, go to step 9.
9. To limit disk space, perform the following steps:
a. Click the Limit volume usage to radio button.
b. In the text box, enter a numerical value to specify the amount of disk space to assign to a particular user. Use
the drop-down box to select kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), or
