At what intervals cloud reclamation/garbage collection run on the AltaVault

Answer

• In AltaVault, cloud reclamation runs when the candidate slab set size reaches five percent of total slabs in the system, or the number of files deleted reaches five percent of total number of files on the AltaVault:
  • When a user deletes a file, the gc.removed_oids counter will increment. This counter divided by the total number of files stored on the AltaVault is displayed as gc.current_removed_oids_pct, and GC will run if it reaches five percent (0.05).
  • When a user deletes a file, the slabs referenced by it are added to the candidate_slabs list.  This counter divided by the total number of slabs on the local cache is displayed as gc.current_candidate_slabs_pct, and GC will run if it reaches five percent (0.05).
  • These thresholds and counters are recorded in stats_megastore and collect_stats/rfsctl-a.log.

gc.current_candidate_slabs_pct: 1.40311

gc.current_removed_oids_pct: 2.0117647

• If you require additional Cloud reclamation checks then you can run the follwoing commands:

enable
Configure terminal
rfsctl exec "-c gc.complete_check"

• You can also schedule a daily GC for example at 10:00 by following: 

enable
Configure terminal
job 1 command 1 "rfsctl exec '-c complete_check'"
job 1 date-time 10:00:00
job 1 recurring 86400
job 1 enable
