Enabling capacity management lets NetApp Workload Factory automatically add incremental storage to an FSx for ONTAP file system as capacity needs change over time. Additionally, enabling this feature removes the need to monitor capacity manually.
About this task
The system scans the FSx for ONTAP file system every 30 minutes. It checks if incremental storage needs to be added and verifies available volume inodes. The count increases based on automatic capacity management thresholds.
Enabling inode management lets NetApp Workload Factory automatically add incremental inodes to an FSx for ONTAP file system as capacity needs change. This feature removes the need for manual inode monitoring.
Only one account can manage this feature.
The maximum amount of SSD storage capacity for all FSx for ONTAP file systems is 524,288 GiB. To request a quota increase, refer to Quotas in AWS FSx for NetApp ONTAP documentation.
Enable automatic capacity management
Enable automatic capacity management to automatically add incremental storage up to the maximum size limit for an FSx for ONTAP file system.
Consider the following before you begin:
-
You must grant credentials with the view, planning, and analysis permission policy in Workload Factory to complete this task.
-
To make sure volume inodes increase along with storage capacity, you must associate a link. Learn how to associate an existing link or to create and associate a new link. After the link associates, return to this operation.
-
You shouldn't enable this feature during data migration because AWS imposes a minimum six-hour cool down period between SSD capacity increases. This restriction might delay adjustments, so plan accordingly.
-
Log in using one of the console experiences.
-
Select the menu
and then select Storage. -
From the Storage menu, select FSx for ONTAP.
-
From FSx for ONTAP, select the actions menu of the file system to enable automatic capacity management for.
-
Select Manage.
-
Under Information, select the pencil icon next to Capacity management. The pencil icon appears next to the drop down arrow when you hover the mouse over the Capacity management row.
-
In the Capacity management dialog, provide the following:
-
Credentials: Select credentials with Automate permissions from the dropdown menu.
-
Select the enable button to Enable automatic capacity management.
Alternatively, disable the feature. If you need to increase file system capacity, you must first disable automatic capacity management.
-
Mode: Select the mode to manage capacity automatically. The options are incremental and adaptive modes.
-
Incremental mode: increases capacity by a fixed amount at thresholds.
-
Warning threshold: Set the warning threshold lower than the threshold increase to trigger a notification from the Workload Factory notification service. The default is 70%.
The warning threshold setting is available only if you enabled the Workload Factory notification service.
-
Threshold increase: Enter the maximum percentage increase for the FSx for ONTAP file system. The default is 80%.
This is the threshold at which Workload Factory triggers a job to increase the capacity. For example, if the file system reaches 80% of capacity, then Workload Factory increases capacity.
-
-
Adaptive mode: predicts and changes capacity based on historical data.
-
Analysis period: Set the analysis period in hours to determine how much historical data to consider for capacity predictions. The default is 120 hours.
-
Planned buffer time: Set the buffer time in hours to ensure capacity is increased before it's actually needed. The default is 48 hours.
-
-
-
-
Select Apply.
A file system scan occurs every 30 minutes to determine whether it needs additional capacity.
Enable capacity notifications
Set up notifications to get alerts when the file system reaches a certain capacity threshold.
You must enable the Workload Factory notification service to use this feature.
-
Log in using one of the console experiences.
-
Select the menu
and then select Storage. -
From the Storage menu, select FSx for ONTAP.
-
From FSx for ONTAP, select the actions menu of the file system to enable automatic capacity management for.
-
Select Manage.
-
Under Information, select the pencil icon next to Capacity management. The pencil icon appears next to the drop down arrow when you hover the mouse over the Capacity management row.
-
In the Capacity management dialog, select Enable capacity notifications to turn on notifications when capacity reaches the threshold and whenever Workload Factory performs an automatic capacity increase.
-
Set the Notification threshold to receive notifications when the file system reaches a certain capacity percentage. The default is 70%.
-
Select Apply.
Enable inode management for a file system
Enable automatic inode management to increase the number of inodes (files) per volume up to the allowable limit.
A scan of the FSx for ONTAP file system occurs every 30 minutes. It verifies available volume inodes and checks if incremental inodes need to be added. The count increases based on automatic inode management thresholds.
|
Terraform users: Terraform has a limitation that requires that all operations are completed within Terraform. Inode management isn't supported in Terraform, but you can enable automatic inode management in the Workload Factory console. |
Consider the following before you begin:
-
To manage volume inodes automatically, you must associate a link. Learn how to associate an existing link or to create and associate a new link. After the link associates, return to this operation.
-
Automatic inode management can be set up with a warning threshold that triggers a notification from the Workload Factory notification service. To use this feature, you must enable the Workload Factory notification service first.
-
You must grant credentials with the view, planning, and analysis permission policy in Workload Factory to complete this task.
-

Select the menu
and then select Storage. -
From the Storage menu, select FSx for ONTAP.

-
Select Manage.
-
Under Information, select the pencil icon next to Automatic inodes management. The pencil icon appears next to the drop down arrow when the mouse hovers over the Automatic inodes management row.
-
In the Automatic inodes management dialog, provide the following:
-
Credentials: Select credentials with Automate permissions from the dropdown menu.
-
Select the enable button to Enable automatic inodes management.
Alternatively, disable the feature. If you need to increase the number of inodes, you must first disable automatic inodes management.
-
Warning threshold: Set the warning threshold lower than the threshold increase to trigger a notification from the Workload Factory notification service. The default is 70%.
The warning threshold setting is available only if you enabled the Workload Factory notification service.
-
Threshold increase: Enter the maximum percentage increase for the number of inodes (files) per volume. The default is 80%.
-
Incremental increase: Enter the percentage to increase the number of inodes (files) incrementally. The default is 10%.
-
-
Select Apply.
A file system scan occurs every 30 minutes to determine if the volumes need additional inodes (files) per volume.
