Removing space management

You can remove space management from a file system by using the dsmmigfs command with the -remove parameter.

Before you begin

Space management must be active on your file system to completely remove it. You can remove space management with a single command. Before you remove space management from your file system, ensure that you have enough space on your file system to recall all migrated files. Ensure also that all activity on your file system is stopped, and that the file system is not being accessed.

About this task

When you remove space management from your file system, the space management client does the following tasks:

  • Runs reconciliation for your file system. If any orphaned stub files are located, a notification is posted. Check the orphan.stubs file in the .SpaceMan directory for a list of orphaned stub files. To remove space management, first resolve all orphaned stub files, and then try again.
  • Determines how much space is required to recall all migrated files. If there is not enough space, the space management client notifies you. To remove space management, make space available and try again.
  • Recalls migrated files to the file system in the most efficient recall order that is based on where they are stored.
  • Notifies the server to delete all migrated files from storage.
  • Deletes the .SpaceMan directory from your file system.
  • Updates information for your native file system.
