      Make utils.RunCmd() deal with interleaved stdout/stderr · 9c233417
      Iustin Pop authored
      Currently, RunCmd is written with the assumption that programs will have
      a small stderr output, therefore we read the child's stdout (which can
      be big, so we don't want to block the child) and then the stderr (which
      is small, so it shouldn't block).
      However, with the ‘gnt-cluster verify-disks’ command, we ourselves
      generate heavy stderr, therefore we break the ganeti-watcher which runs
      the verify-disks via utils.RunCmd.
      This patch turns the RunCmd command into an poll-based one, which means
      any kind of interleaved output by a child on stdout/stderr will be
      handled correctly. Of course, since the output is buffered in memory,
      there are other ways to break RunCmd(). But at least this should fix the
      common case.

      Internal API change for instance console access. · 30989e69
      Alexander Schreiber authored
      Change the internal hypervisor API for GetShellCommandForConsole, we
      now call it with the instance instead of just the instance name.
      This is a prep patch for HVM, since HVM needs more than just the instance
      name to determine a way of console access.

      Handle ^C while trying to acquire the lock · 36c68ff1
      Iustin Pop authored
      When waiting for the lock and pressing ^C, the user will get a backtrace
      as the KeyboardInterrupt exception is not handled. The patch adds a
      simple method of handling it.
      Note that this is not about ^C in any other place.

      Add LUVerifyDisks · 2c95a8d4
      Iustin Pop authored
      This patch adds a new LUVerifyDisks that implements the OpVerifyDisks.
      The algorithm is that by determining not-used logical volumes for
      instances that are supposed to be running, we presume from there that
      the DRBD devices are not online and therefore one should
      ‘activate-disks’ for those instances.

      Return more data in rpc.call_volume_list · cb2037a2
      Iustin Pop authored
      Currently, the volume_list call returns only the volume size. However,
      it is useful to also have two other things: the 'inactive' state of the
      volume (which might trigger a ‘vgchange -a y’ on the volume group) and
      the online state (which shows if the volume is in use or not).
      Since this modifies an RPC call, we also bump the protocol version,
      although the single user of the call didn't care about the dictionary
      values, only about the keys.

      Fix parsing of drbdsetup show output · c522ea02
      Iustin Pop authored
      This fixes the parsing of integers in the drbdsetup show output with
      newer pyparsing versions.
      Basically, the convert-to-int action that we use was taken from the
      example documentation of an older pyparsing version that automatically
      uses only the second element if the result is returned as a tuple, but
      this was deprecated for a while and removed in 1.4.3.
      Based on a nice report by Jorge Cabello <jorge@aspl.es>, and
      confirmation about pyparsing behaviour from its author. Thanks!

      Split the change of peer in secondary replace in two operations · 642445d9
      Iustin Pop authored
      This patch splits the single operation of replace peer into two distinct
      phases, in order to make a single change to the instance configuration:
        - detach from network
        - if at least one drbd device succeeded, make one change to the
          instance, pointing all disks to the new peer
        - attach to the new peer
      This should eliminate the case when a failure in the second reattach can
      leave the instance with two secondaries.
