Answer

  • User-Default: This applies to CIFS, FCP, iSCSI, and/or NFS workloads from client systems, and the specific volumes are not listed or are summarized
    • Use the command qos statistics volume resource cpu show to determine the top volume workloads
    • The output is the same as qos statistics workload resource cpu show but only lists volumes and not background workloads
  • _DEDUP, _Efficiency_Besteffort, or _Efficiency_Background: Deduplication or other storage efficiency jobs
  • _SNAPMIRROR: This could apply to SnapMirror or SnapVault workloads
  • _WAFL_SCAN: Background WAFL scanners, mainly used for SnapMirror or snapshot workloads, and viewable with the wafl scan status command
  • _RAID or _RAID_SCRUB: Background RAID workloads, potentially RAID scrubs
  • _ocs_vserver: Copy offload
  • _Tape-Backup: A tape backup
  • _Aged-Out-Work: Idle workloads
  • System-Default: Internal ONTAP workloads that includes all background workloads not explicitly defined (like SnapMirror and Dedup)
    • This can include snapshot clones, raid scrubs, and other background tasks
    • Anything not covered by a separate workload that is a background process
