      Introduce a wrapper for hostname resolving · 104f4ca1
      Iustin Pop authored
      
      
      Currently a few of the LU's CheckPrereq use utils.HostInfo which raises
      a resolver error in case of failure. This is an exception from the
      standard that CheckPrereq should raise an OpPrereqError if the error is
      in the 'pre' phase (so that it can be retried).
      
      This patch adds a new error code (resolver_error) and a wrapper over
      utils.HostInfo that just converts the ResolverError into
      OpPrereqError(…, errors.ECODE_RESOLVER). It then uses this wrapper in
      cmdlib, bootstrap and some scripts.

      Add uuid on node/instance add and cluster init · 430b923c
      Iustin Pop authored
      
      
      This patch does a little bit of cleanup first, since we want to call
      GenerateUniqueID without reacquiring the lock.
      
      Note that we don't necessarily need to do this for the cluster, since at
      first startup ConfigWriter will do it anyway. But it's better to
      explicitely do this instead of relying on the automated upgrade.
      
      Additionally this patch adds ctime/mtime population at cluster init
      time. mtime is not necessarily needed (master will update it
      automatically, but we're doing it anyway for consistency).

      Get rid of the default_hypervisor slot · 066f465d
      Guido Trotter authored
      
      
      Currently we have both a default_hypervisor and an enabled_hypervisors
      list. The former is only settable at cluster init time, while the latter
      can be changed with cluster modify.
      
      This becomes cumbersome in a few ways: at cluster init time for example
      if we pass in a list of enabled hypervisors which doesn't include the
      "default" xen-pvm one, we're also forced to pass a default hypervisor,
      or an error will be reported. It is also currently possible to disable
      the default hypervisor in cluster-modify (with unknown results).
      
      In order to avoid this we get rid of this field altogether, and define
      the "first" enabled hypervisor as the default one. This allows ease of
      changing which one is the default, and at the same time maintains
      coherency.
      
      At configuration upgrade we make sure that the old default is first in
      the list, so that 2.0 cluster defaults are preserved.

      Simplify InitConfig and remove SimpleConfigWriter · a33848a5
      Guido Trotter authored
      
      
      InitConfig currently creates the cluster config_data, then puts it into
      a dict, passes it to SimpleConfigWriter to load it from a dict (which
      just reuses the dict value) and then saves it. The SimpleConfigWriter is
      then returned, but ignored. With this patch we just write out the
      config_data at InitConfig time, and thus can remove SimpleConfigWriter
      altogether. The now unused SimpleConfigReader.FromDict is also gone.

      InitCluster, don't use SimpleConfigWriter · 9e1333b9
      Guido Trotter authored
      
      
      InitConfig returns a SimpleConfigWriter to InitCluster, which then
      passes it on to ssh.WriteKnownHostsFile, which extracts a couple of
      values from it. One line later the full ConfigWriter is initialized.
      
      By initializing it one line before we can pass the full writer to
      ssh.WriteKnownHostsFile, and thus we don't need to care anymore for the
      InitConfig returned SimpleConfigWriter

      Create runtime dir in bootstrap · 9dae41ad
      Guido Trotter authored
      Some hypervisors (KVM) need RUN_GANETI_DIR to exist even at cluster init
      time. This patch creates it in InitCluster just before hv parameter
      checking. Since the code to make list of directories is already repeated
      twice in the code, and this would be the third time, we abstract it into
      an utils.EnsureDirs function and we call that one from ganti-noded,
      ganeti-masterd and bootstrap.
