Verifier design and architecture

This section describes in detail the concept of each verifier and shows each check used in individual actions. At the same time, you will find here the individual steps for each check.

All checks of the action are performed in sequence and their results are aggregated into one. For the result to be successful, all checks must be successful.

List of supported verifiers:

• Ceph-mon verifier
  • check Juju version
  • check Ceph Monitor quorum
  • check Ceph clusters health
• Ceph-osd verifier
  • check Ceph cluster health
  • check the minimum number of replicas
  • check availability zones resources
• Nova-compute verifier
  • check running VMs
  • check availability zones
• Neutron-gateway verifier
  • check minimum Juju version
  • check active HA router
  • check LBaasV2 present
  • check neutron-gateway redundant routers
  • check neutron-gateway redundant DHCP
• OVN-central verifier
  • supported charm version
  • check single application
  • check leader consistency
  • check uncommitted logs
  • check unknown servers
  • check reboot

If you find that a check does not take into account all possible circumstances or its assumption is wrong, do not hesitate to report a bug.
