Resetting lost and missing object counts

After investigating the StorageGRID system and verifying that all recorded lost objects are permanently lost or that it is a false alarm, you can reset the value of the Lost Objects attribute to zero.

Before you begin

About this task

You might see the Lost Objects attribute on the following pages:
  • Select Nodes. Then select Storage Node > Objects.
  • Select Support > Grid Topology. Then select site > Storage Node > LDR > Data Store > Overview > Main.
  • Select Support > Grid Topology. Then select site > Storage Node > DDS > Data Store > Overview > Main.

This example shows the LDR > Data Store page.

Steps

  1. Select Support > Grid Topology.
  2. Select Site > Storage Node > LDR > Data Store > Configuration for the Storage Node that has raised the (LOST) Lost Objects alarm.
  3. Select Reset Lost Objects Count.

  4. Click Apply Changes.
    The Lost Objects attribute is reset to 0 and the LOST (Lost Objects) alarm clears. It can take a few moments for the Lost Objects attribute to reset and the alarm to clear.
  5. Optionally, reset other related attribute values that might have been incremented in the process of identifying the lost object.
    1. Select Site > Storage Node > LDR > Erasure Coding > Configuration.
    2. Select Reset Reads Failure Count and Reset Corrupt Copies Detected Count.
    3. Click Apply Changes.
    4. Select Site > Storage Node > LDR > Verification > Configuration.
    5. Select Reset Missing Objects Count and Reset Corrupt Objects Count.
    6. If you are confident that quarantined objects are not required, you can select Delete Quarantined Objects.

      Quarantined objects are created when background verification identifies a corrupt replicated object copy. In most cases StorageGRID automatically replaces the corrupt object, and it is safe to delete the quarantined objects. However, if a Lost Objects alarm is triggered, technical support might want to access the quarantined objects.
