Manage your storage pool

This page describes how to edit storage pool settings or delete a storage pool.

Edit storage pool settings

You can change the following settings after you create a storage pool:

Storage pool capacity
You can resize storage pool capacity to control charges. Storage pool capacity is adjustable in 1 GiB increments. You can't decrease pool capacity below the sum of all capacity of the volumes attached to the pool. Pools with Flex service level can't be decreased in capacity. Pools with Flex custom performance can only be increased once every four hours.
Performance
Pools with the Flex zonal custom performance service level lets you adjust throughput, but only once every four hours.
Active Directory policy
You can attach an Active Directory policy to a storage pool that doesn't already have an Active Directory policy. You can modify the Active Directory policy, however, you can't replace a policy that is already attached to a pool with another policy.

Adding an Active Directory policy doesn't affect existing volumes in a pool.
Auto-tiering settings
For Premium and Extreme pools, you can enable auto-tiering only once for a pool. Your selection is permanent. Once auto-tiering is enabled, it can't be disabled.
For custom-performance Flex zonal pools with auto-tiering enabled, you can adjust the Hot tier threshold by increasing its size and also enable or disable auto-increase.
Pool description and labels
You can change storage pool descriptions and add, modify, or delete labels.

Switch active and replica zones

Regional storage pools of Flex service level replicate data synchronously between two zones. The active zone serves all volumes of the pool, while the replica zone acts as a standby. If the active zone stops working, NetApp Volumes automatically switches the NFS or SMB service to the replica zone. While this switch happens after a brief I/O pause, file service operations resume without any data loss.

File service operations from clients in the previously active zone can have increased latency because of the cross-zone traffic with the newly active zone. Note that cross-zone exit from the clients can incur a Compute Engine inter-zone data transfer charge. For pricing information, see Network Pricing.

You can also trigger a zone switch manually, and this can also cause an I/O pause.

Use the following instructions to switch a zone manually using the Google Cloud console or Google Cloud CLI.

Console

  1. Go to the NetApp Volumes page in the Google Cloud console.

    Go to NetApp Volumes

  2. Click Storage pools.

  3. Click the name of the regional Flex storage pool you want to fail over.

  4. Click Switch active/replica zones.

  5. Review the current zone versus replica zone settings and the new settings that appear in the dialog.

  6. Click Switch to proceed.

  7. Read through the confirmation dialog and enter the name of the pool and then click Switch.

After the switch operation ends, your active zone and replica zone will have changed roles.

gcloud

Switch a zone manually:

    gcloud netapp storage-pools switch STORAGE_POOL_NAME \
       --project=PROJECT_ID \
       --location=LOCATION \

Replace the following information:

  • STORAGE_POOL_NAME: the name of the storage pool. This name must be unique per location.

  • PROJECT_ID: the name of the project you want to create the storage pool in.

  • LOCATION: the location for the pool.

For more information on additional optional flags, see Google Cloud SDK documentation on storage-pools switch.

Delete a storage pool

You can delete storage pools to control charges. Use the following instructions to delete a storage pool:

  1. Go to the NetApp Volumes page in the Google Cloud console.

    Go to NetApp Volumes

  2. Click Storage pools.

  3. Select the storage pool you want to delete.

  4. Click Delete.

  5. To confirm deletion, enter the name of the storage pool.

  6. Click Delete.
