Quotas
Quotas are configured by accessing the
Storage > Quotas
page of the Web Management
Interface. This default page shows all volumes on the cluster and their space/file quotas.
Assigning quotas ensures that no one user or group consumes a disproportionate amount of
volume capacity measured by either space consumed or number of files created. The
Quotas
page also displays space consumed and files created by each user or LDAP/NIS group
regardless of whether a quota is applied to them, allowing for precise tracking of usage
patterns. You can set individual quotas for any LDAP, NIS, Windows domain, or local user
known to the SnapScale. Group quotas are available only for LDAP/NIS groups.
For users and groups, there are no pre-assigned default quotas on the SnapScale. When
quotas are assigned, you can assign a default space or file quota for all users, or allow all users
to have unlimited space on the volume. Unless you assign individual user or group quotas, all
users and groups will receive the default quota.
In calculating usage, the SnapScale looks at all the files on a volume that are owned by a
particular user and adds up the file sizes. Every file is owned by the user who created the file
and by the primary group to which the user belongs. When files are copied to the cluster, their
size and count are applied against both the applicable user and LDAP/NIS group quotas.
Default Quotas
On the main
Quotas
page (
Storage > Quotas
), the last two columns of the table show the
default quotas for disk space and number of files. To change these settings, click the number
(or no space/file limit text) in the row under the default space or file quota column. A page is
shown for the appropriate quota type options:
