sanitize-config

+++++++++++++++

This tool takes the Ganeti configuration and outputs a "sanitized"

version, by randomizing or clearing:

- DRBD secrets and cluster public key (always)

- host names (optional)

- IPs (optional)

- OS names (optional)

- LV names (optional, only useful for very old clusters which still have

  instances whose LVs are based on the instance name)

By default, all optional items are activated except the LV name

randomization. When passing ``--no-randomization``, which disables the

optional items (i.e. just the DRBD secrets and cluster public keys are

randomized), the resulting file can be used as a safety copy of the

cluster config - while not trivial, the layout of the cluster can be

recreated from it and if the instance disks have not been lost it

permits recovery from the loss of all master candidates.
