mode

The metadata configuration mode for provisioning Metadata IOPS for an FSx for Lustre file system using a PERSISTENT_2 deployment type.

• To increase the Metadata IOPS or to switch an SSD file system from AUTOMATIC, specify USER_PROVISIONED as the value for this parameter. Then use the Iops parameter to provide a Metadata IOPS value that is greater than or equal to the current number of Metadata IOPS provisioned for the file system.

• To switch from USER_PROVISIONED mode on an SSD file system, specify AUTOMATIC as the value for this parameter, but do not input a value for Iops. + If you request to switch from USER_PROVISIONED to AUTOMATIC mode and the current Metadata IOPS value is greater than the automated default, FSx for Lustre rejects the request because downscaling Metadata IOPS is not supported.

• AUTOMATIC mode is not supported on Intelligent-Tiering file systems. For Intelligent-Tiering file systems, use USER_PROVISIONED mode.
