# CPU tuning
# This is left commented so the section of the tasks never runs; enable or disable it in your per-cluster configs
# CPU tune options defined per-node are placed in the pvc_nodes section below under cpu_tuning; global versions
# may be placed here instead.
# Whether a node has hyperthreading is determined automatically; if so, for each (real) CPU core assigned to a
# subscection, its corresponding hyperthread is also assigned to that section.
# machine_cpus is later used in the templates; the value of this field is autogenerated as:
# total_system_cpus - osd_cpus - system_cpus
#cpu_tuning:
# enabled: yes # Enable or disable CPU tuning for processes
# nodes: # Nodes configuration; default options, can be overridden by per-node tuning below
# system_cpus: 2 # The number of CPUs to assign to the "system" slice
# # This slice includes all non-VM, non-OSD processes including databases, node daemons, system processes, non-OSD Ceph processes, etc.
# # At least 2 cores should be assigned to this slice.
# osd_cpus: 2 # The number of CPUs to assign to the "osd" slice
# # This slice includes all OSD processes
# # At least 1 core per OSD should be assigned to this slice.
# VM Autobackup
# This is uncommented but disabled so this is not installed by default; enable it in your per-cluster configs
# Autobackup allows the exporting of VM backups automatically to an external disk target.
# These values are default; ensure you modify them in your own group_vars to match your system!
