    Description

      During migration, the MDT FID of the migrated file is changed to reflect the new MDT the inode is stored on. However, it would be possible to keep the user-visible inode constant after migration by storing the original FID into the LMA as a new field. If present, this saved FID could be used to generate the inode number for userspace instead of the current FID so that it doesn't affect user tools such as backups.
