Answer

The following are the Element Software Garbage Collection Events (gcEvents) that can be seen in SolidFire Active IQ and the Element UI:

  • GCStarted = Garbage Collection has been initiated.  This will automatically occur every hour at the top of the hour.
  • GC Cluster Coordination Complete = All participating Slice and Block Services are confirmed by Garbage Collection and GC is ready.  This message should immediately follow GCStarted. 
  • GCCompleted = Garbage Collection complete and you should see one of these events for every participating block service (BS) that is noted in the GCStarted event.
  • GCStartDeferred – GC already in progress* = GC start was deferred due to GC already running
  • GCAborted = any reason GC failed to start.  Information on the cause of the abort will be found in the Details section of the Active IQ Events and Element UI Event Log.
  • GCFailed - Garbage collection started but failed to complete. Generally, this can be seen with intermittent network-related timeouts such as issues found in the following KB: Intermittent unresponsiveService is reported 

*Note – GCStartDeferred is introduced in Element Software 12.7.  Prior versions would report a GCAborted Event if the GC was already running when the next GC start initiated.

Additional Information

Should Garbage Collection fail to complete in 12 or more hours, a support case will be created for NetApp Support to investigate.
