Reconciling file systems overview

When you modify or delete a migrated or premigrated file on the local file system, the migrated copy in Tivoli® Storage Manager server storage becomes obsolete. During reconciliation, any obsolete copies of migrated or premigrated files are marked for expiration. When the copies expire, they are removed from the server.

The default interval for reconciliation is 24 hours. When reconciliation is not driven by GPFS™ policy, the root user can set the reconcile interval with the reconcileinterval option. If you have many space-managed file systems on a system, increase this value to reduce the impact that the dsmreconcile command might have on system performance.
