Fix a few job archival issues

LoadJobFromDisk can return 'None' for no-such-job, and we shouldn't add
None to the job list; we can't anyway, as this raises an exception:

  Caught exception: cannot create weak reference to 'NoneType' object

After fixing this, job archival of missing jobs will just continue
silently, so we modify gnt-job archive to log jobs which were not
archived and to return exit code 1 for any missing jobs.

activate the master IP and then, if the start_daemons parameter is true,
it will also activate the master role.

While this works, it has two issues:

- first, it will activate the master IP unconditionally, even if this
  node will not start the master daemon due to missing votes
- second, the activation of the IP is done twice if start_daemons is
  true, because the master daemon does its own activation too

This behaviour seems to be unmodified since Summer 2008, so probably any
rationale on why this is done in two places is forgotten.

The patch changes so that this function does *either* IP activation or
master role activation but not both. So the IP will be activated only
once (from the master daemon or from LURenameCluster), and it will only
be done if the masterd got enough votes for startup.

I can see only one downside to this change: if masterd won't actually
start (due to missing votes), RAPI will still start, and without the
master IP activated. But this is no worse than before, when both RAPI
was running and the IP was activated.

Normally this is not a problem, but in cases where one does quick master
failovers, this creates a race condition which hits the QA scripts

To solve this, and make the startup process cleaner (the system is in

Move the UsesRPC decorator from cli to rpc

This is needed because not just the cli scripts need this decorator, but
the master daemon too (and it already duplicated the code once).

In cli.py we just leave a stub, so that we don't have to modify all the
scripts to import rpc.py.

We then change the master daemon code to reuse this decorator, instead
of duplicating it.

14 years agowatcher: smarter handling of instance records

watcher: smarter handling of instance records

This patch implements a few changes to the instance handling. First, old
instances which no longer exist on the cluster are removed from the
state file, to keep things clean.

Second, the instance restart counters are reset every 8 hours, since
some error cases might be transient (e.g. networking issues, or machine
temporarily down), and if the problem takes more than 5 restarts but is
not permanent, watcher will not restart the instance. The value of 8
hours is, I think, both conservative (as not to hammer the cluster too
often with restarts) and fast enough to clear semi-transient problems.

And last, if an instance is not restarted due to exhausted retries, this
should be warned, otherwise it's hard to understand why watcher doesn't
want to restart an ERROR_down instance.

Update the RAPI client for the migration mode

See the discussion on the previous patch about this. Basically unless we
want to a add a new 'feature' marking for the live migration parameter,
there is no simple way to handle this nicely in the client.

Given that the client was/is marked as experimental, this patch simply
replaces live with mode. This means that this client won't work with 2.1
clusters…
