FSx for OpenZFS file systems should be configured for Multi-AZ deployment
Description
This control checks whether an Amazon FSx for OpenZFS file system is configured to use the multiple Availability Zones (Multi-AZ) deployment type. The control fails if the OpenZFS file system isn't configured for Multi-AZ deployment. Amazon FSx for OpenZFS offers several deployment types: Multi-AZ (HA) provides high availability by using a pair of file servers spread across two Availability Zones, Single-AZ (HA) is a single Availability Zone deployment with high availability, and Single-AZ (non-HA) is a single Availability Zone deployment without high availability. The Multi-AZ (HA) deployment type is recommended for most production workloads due to its superior availability and durability model.
Remediation
To configure your FSx OpenZFS file system for Multi-AZ deployment, you need to create a new file system with Multi-AZ deployment type.
Steps
- Navigate to the Amazon FSx console
- Choose 'Create file system'
- Select 'OpenZFS' as the file system type
- In the 'Deployment type' section, select 'Multi-AZ (HA)'
- Configure other settings as needed
- Create the file system with Multi-AZ deployment
- Migrate your data from the single-AZ file system to the new Multi-AZ file system
- Update your applications to use the new Multi-AZ file system
- Delete the old single-AZ file system once migration is complete
