The dsmdf command displays the following information for one or more file systems:
For AIX GPFS file systems only: Remotely-managed file systems within the local GPFS node set (r)
Only migration and recall processes dynamically update status information for your file systems. If any other process changes the state of a file, the change is not reflected in the information that the dsmdf command displays until reconciliation is run.
For AIX GPFS file systems only: Migrating newly-created files of less then five minutes might display incorrect results (resident size) when you use the dsmdf and dsmdu commands. This is because GPFS is not synchronized on all nodes when you migrate files. The last block of a file is not released from the disk although the file migrated successfully. This can cause a deviation from an assumed disk usage if many small files are migrated and the block size is high.
