Storage efficiency never completes and restarts with the "sis.chkpoint.restore.failed" error
Applies to
- ONTAP 9
- Storage efficiency (deduplication)
- SnapMirror or SnapVault
Issue
The efficiency operation fails to restore from the last checkpoint after a SnapMirror or SnapVault update has stopped it. This causes the operation to restart from the beginning continuously.
