You can create a quota on a directory, with or without specifying quotas for individual users and groups.
For a simple directory quota, only do the procedures given below in the section Create a Directory Quota. For a directory quota with user and group quotas, do the instructions given in the sections Create a Directory Quota and Configure User/Group Quotas below.
-
From the left navigation menu, select Element Store and then Quotas.
-
Click Create Quota to open the Add Quota tab.
-
In the Quota Rules tab, complete the fields:
Field
Description
Tenant (required)
Select a tenant if you want to specify that the quota should serve a non-default tenant.
Name (required)
A unique name for the quota.
Path (required)
The path to the directory.
The quota applies to the entire directory, including all subdirectories. If a quota configured on a subdirectory is bigger than the quota on its parent directory, the more restrictive quota applies.
Default Email
Emails are sent to users if and when they exceed their user/group quota limits. Default Email is a default email address that is used instead of a user's email address in the event that no email address is found for the user on a provider and no email suffix is set in the Quota Setup area of the Notifications settings.
For more information about this feature, see Managing User Quota Emails .

Optionally, set the soft limit for the quota:
-
Optionally, set the hard limit for the quota:
Field
Description
Capacity
Storage usage limit, above which no further writes are allowed.
When the hard limit is reached, the HARD_EXCEEDED alarm is triggered.
The value must be a complete integer and must be specified with a unit of measurement. Do not insert a space between the value and the unit of measurements. Valid units are:
The units are case-insensitive. For example:
4gbis valid.Files & Directories
Number of directories and unique files under the path, above which no writes are allowed. A file with multiple hard links is counted only once.
-
Enable Create Directory to create the directory if the directory was not created yet. If this option is disabled and the directory doesn't exist, the quota will not be created.
-
If you want to enable user and/or group quotas on the directory, toggle Enable User/Group Quotas on and configure user and/or group quotas.
-
If you enabled the Enable User/Group Quotas setting, you can:
-
Optionally, use the fields under Default User Rule and/or Default Group Rule to define a default rule to apply quota limits to all users or groups individually. If you do notdefine a default rule, users/groups are only limited individually by any individual user and group rules that you configure in the User Rules and Group Rules tabs. If you define a default rule and you also define individual user rules, the individual user rules override the default user rule. Similarly, rules defined for specific groups override the default group rule.
-
Complete these fields under Soft limit to set a soft limit:
Field
Description
Capacity
The limit of capacity usage by the user or group at which warnings of exceeding the quota are issued, and the grace period countdown commences.
Files & Directories
This is a limit on the number of directories and unique files in the quota directory that the user or group can create, which is not enforced until the grace period is reached.
If the user or group exceeds this limit, a warning is sent by email unless alarms are disabled. A file with multiple hard links is counted only once.
Grace period
Set this value to trigger an alarm and block write operations to the directory if the user or group exceeds either the capacity soft limit or the files and directories soft limit for a specified time period.
If the grace period is not set, the user or group is only write blocked if and when the user or group reaches one of the hard limits.
Specify the grace period in the format:
[DD] [HH:[MM:]]ss. For example:-
To specify 30 days, 20 hours, 15 minutes and 10 seconds, enter
30 20:15:10. -
To specify 18 minutes, enter
18:00. -
To specify 20 hours, enter 20:00:00.
-
You can also specify time in days, hours, minutes or seconds, in the format, for example 10d, 10h, 10m or 10s. The parameter is case-sensitive, entering 10D or 10H will return an error.
-
-
Complete these fields under Hard limit to set a hard limit:
Field
Description
Capacity
The capacity usage limit beyond which no writes will be allowed for the user.
The value must be a complete integer and must be specified with a unit of measurement. Do not insert a space between the value and the unit of measurements. Valid units are:
The units are case-insensitive. For example:
4gbis valid.Files & Directories
The number of directories and unique files in the quota directory that the user can create.
A file with multiple hard links is counted only once.
-
-
Toggle Enable Alarms on or off to enable or disable raising of VMS alarms when users or groups exceed their limits.
If user/group quotas are enabled, alarms are enabled by default on the following events, which can be managed as Event Definitions:
-
A threshold event that monitors the number of users exceeding their quotas. According to the default event definition, an alarm of major severity is raised when one or more users exceed their user quota limits on the quote. The alarm notification reports the number of users that exceeded their quota.
-
A threshold event that monitors the number of users that are blocked from writing to the quota. Per the default event definition, an alarm of critical severity is raised when one or more users is blocked from writing to the quota.
You can use this setting to disable these alarms for the quota.
This setting does not affect emails sent to users when they exceed quota limits. Such emails continue to be sent when this setting is disabled.
-
-
Toggle Enable getting emails from Active Directory/LDAP on or off to allow or prohibit querying of providers for email addresses used to send email notifications when a quota is exceeded.
-
-
Click Create.
Quota creation now begins. The process is asynchronous and you can track the quota's state in the Quotas page.
If you enabled user/group quotas, you can create rules that restrict the usage of each user and/or group. These rules override the Default User Rule and Default Group Rule, if configured in the Quota Rules tab, for those users and groups bound by these rules.
To configure a user quota or a group quota:
-
Go to the User Rules or Group Rules tab of the Add Quota dialog and click Add Rule.
-
Specify how you want to identify the user or group for which a rule is created. Do either of the following:
-
Select username or groupname in the Identifier Type field and type the name of the user or group in the Identifier field.
-
Select uid or gid in the Identifier Type field and enter the UID or GID in the Identifier field.
-
-

Grace period
Set this value to trigger an alarm and block write operations to the directory if the user or group exceeds either the capacity soft limit or the files and directories soft limit for a specified time period.
If the grace period is not set, the user or group is only write blocked if and when the user or group reaches one of the hard limits.

To create a directory quota, use the quota create command. This includes creating default user and group quotas but not any additional user or group quotas.
To add non-default user or group quota rules to a directory quota, use the userquota create command.
