AWS fsx documentation change

Service: fsx · 2025-11-07 · Documentation low

File: fsx/latest/LustreGuide/efa-file-systems.md

Summary

Added documentation section 'Creating an EFA-enabled file system' with CLI command example for EFA-enabled Lustre file system creation

Security assessment

The change adds procedural documentation for creating EFA-enabled file systems but does not address security vulnerabilities or introduce new security features. The CLI example includes standard security parameters (security-group-ids, subnet-ids) but these are part of normal AWS resource configuration.

+## Creating an EFA-enabled file system
+
+This section contains instructions on how to create an FSx for Lustre EFA-enabled file system using the AWS CLI. For information on how to create an EFA-enabled file system using the Amazon FSx console, see [Step 1: Create your FSx for Lustre file system](./getting-started.html#getting-started-step1).
+
+Use the [create-file-system](https://docs.aws.amazon.com/cli/latest/reference/fsx/create-file-system.html) CLI command (or the equivalent [CreateFileSystem](https://docs.aws.amazon.com/fsx/latest/APIReference/API_CreateFileSystem.html) API operation). The following example creates an FSx for Lustre EFA-enabled file system with a `PERSISTENT_2` deployment type.
+    
+    
+    aws fsx create-file-system\
+       --storage-capacity 4800 \
+       --storage-type SSD \
+       --file-system-type LUSTRE \
+       --file-system-type-version 2.15 \
+       --subnet-ids subnet-01234567890 \
+       --security-group-ids sg-0123456789abcdefg \
+       --lustre-configuration '{"DeploymentType": "PERSISTENT_2", "EfaSupport": true}'
+
+After successfully creating the file system, Amazon FSx returns the file system's description in JSON format.
