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 from AUTOMATIC mode, 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.

    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.
