From the left navigation menu, select Element Store and then Quotas.
The following information is listed for each quota:
Name
The name of the quota
State
The state of the quota:
OK. The quota was created. The directory is not exceeding any of the limits.
FAILED. Quota creation failed.
SOFT_EXCEEDED. The directory has exceeded the quota soft limit.
HARD_EXCEEDED. The directory has exceeded the quota hard limit.
GRACE_EXPIRED. The soft limit was exceeded for the extent of the grace period.
NODE_SOFT_EXCEEDED. The directory exceeded the quota soft limit on the number of files and directories.
NODE_HARD_EXCEEDED. The directory exceeded the quota hard limit on the number of files and directories.
Path
The directory path controlled by the quota.
Hard limit
The capacity usage limit beyond which writes are blocked.
Soft limit
The capacity usage limit beyond which warnings are issued.
Used Effective Capacity
The amount of quota capacity in use, which is calculated by counting each used block of 32 KB or less as 32KB. A file that is smaller than 32KB is counted as using up 32KB of quota capacity.
Hard limit Files/Directories
The hard limit on files and directories in the directory controlled by the quota.
Soft limit Files/Directories
The soft limit on files and directories in the directory controlled by the quota.
Used Files/Directories
The current count of files and directories inside the directory controlled by the quota.
Grace period
The grace period, if configured, which limits how much time the soft limit can be exceeded.
Grace period expiration
The time remaining until the end of the grace period. Displayed when soft limit is exceeded.
From the left navigation menu, select Element Store and then Quotas.
Click Create Quota.

Complete the fields:
Field
Description
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.
Hard limit (required)
Storage usage limit beyond which no writes will be 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.Soft limit
Storage usage limit at which warnings of exceeding the quota are issued.
Hard limit Files/Directories
Number of directories and unique files under the path beyond which no writes will be allowed. A file with multiple hardlinks is counted only once.
Soft limit Files/Directories
Number of directories and unique files under the path at which warnings of exceeding the quota will be issued. A file with multiple hardlinks is counted only once.
Grace period
Set this value to trigger an alarm and block write operations to the directory if the storage usage continues to exceed the soft limit for a specified time period.
If the grace period is not set, the directory is only blocked if and when usage reaches the hard limit.
Specify the grace period in the format:
[DD] [HH:[MM:]]ss. Examples:To specify 30 days, 20 hours, 15 minutes and 10 seconds, enter
30 20:15:10.To specify 18 hours, enter
18:00.
Create Directory
Enable this to create the directory if the directory was not created yet.
If Create Directory is disabled and the directory doesn't exist, the quota will not be created.

Click Create.
Quota creation now begins. The process is asynchronous and you can track the quota's state in the Quotas page.
To monitor the cluster capacity allocated to quotas, browse to the Analytics page and select the predefined Cluster Quota Capacity report. The report shows two time sampled metrics:
Quota Used Capacity. The total cluster capacity allocated to quotas and used.
Quota Allocated Capacity. The total cluster capacity allocated to quotas.
As with other Analytics reports, the report displays the capacity metrics in either base2 or base10 units depending on the units of measurement set for the VAST Web UI. For information about changing the displayed units, see Changing Units of Measurement.
