    Description

      Currently after device address is changed tunefs should be started with
      "writeconf" options. This erase configuration logs for the filesystem
      that this server is part of, and regenerate them. This is very dangerous.
      All clients must be unmounted and servers for this filesystem should be
      stopped. All targets (OSTs/MDTs) must then be restarted to regenerate
      logs. No clients should be started until all targets have restarted.
      The targets start order is also important. Wrong order can be cause of
      failure.
