      Fix gnt-instance info i1 i2 ... · 515207af
      Guido Trotter authored
      Due to an indentation error only the last instance queried got returned by
      LUQueryInstanceData. Moving the append() call inside the for cycle to fix this
      issue.
      
      This is a one-liner targeted at 1.2.3

      Alter the device activation code · 40a03283
      Iustin Pop authored
      This tiny patch fixes the breakage that the previous patch about
      activation did by removing the Close() call after activation.
      
      The initial reason for that call was that if the device is already
      active and open, but we need it closed, we close it automatically.
      
      This however conflicts with the 2-step open in the case the instance is
      already open.
      
      It makes sense to remove the call since in the current Ganeti setup,
      just doing Close() is not enough to change the device from (e.g.)
      primary to secondary, as some devices (e.g. md) might need Shutdown not
      Close.
      
      It also gets rid of a Close() in the CreateBlockDevice function, due to
      the same reasoning (although in Create the child should not have a
      different status anyway).

      creating instances it logs the secondary node too (even if this doesn't
      apply for plain templates, it doesn't create an error).

      Modify the default output of gnt-instance list · d8052456
      Iustin Pop authored
      This patch adds a new field available for selection in gnt-instance list
      names "status" which represents the combined value of "admin_state" and
      "oper_state". Since this is much easier to parse (e.g. gnt-instance list
      |grep ERROR), we also modify the default field list to use this instead
      of the admin/oper state fields.

      Parse double protocol version in drbd8.2 · c3f9340c
      Guido Trotter authored
      DRBD 8.2 uses a double integer field ad protocol version, rather than a single
      one. This patch fixes the ganeti parsing code, allowing both the old and the
      new version type. In order to do so the internal _GetVersion function is
      changed to return a dict, rather than a list, and the second protocol field is
      added, only if present, as proto2.
      
      This is a fix for issue 24.

      Reduce the chance of DRBD errors with stale primaries · fdbd668d
      Iustin Pop authored
      This patch is a first step in reducing the chance of causing DRBD
      activation failures when the primary node has not-perfect data.
      
      This issue is more seen with DRBD8, which has an 'outdate' state (in
      which it can get more often). But it can (and before this patch, usually
      will) happen with both 7 and 8 in the case the primary has data to sync.
      
      The error comes from the fact that, before this patch, we activate the
      primary DRBD device and immediately (i.e. as soon as we can run another
      shell command) we try to make it primary. This might fail - since the
      primary knows it has some data to catch up to - but we ignored this
      error condition. The failure was visible later, in either md failing to
      activate over a read-only storage or by instance failing to start.
      
      The patch has two parts: one affecting bdev.py, which changes failures
      in BlockDev.Open() from returning False to raising
      errors.BlockDeviceError; noone (except a generic method inside bdev.py)
      checked this return value and we logged it but the master didn't know
      about it; now all classes raise errors from Open if they have a failure.
      
      The other part, affecting cmdlib.py, changes the activation sequence
      from:
        - activate on primary node as primary and secondary as secondary, in
          whatever order a function returns the nodes
      to the following:
        - activate all drives as secondaries, on both the primary and the
          secondary nodes of the instance
        - after that, on the primary node, re-activate the device stack as
          primary
      
      This is in order to give the chance to DRBD to connect and make the
      handshake. As noted in the comments, this just increases the chances of
      a handshake/connect, not fixing entirely the problem. However, it is a
      good first step and it passes all tests of starting with stale (either
      full or partial) primaries, with both drbd 7 and 8, and also passes a
      burnin.
      
      Note that the patch might make the device activation a little bit
      slower, but it is a reasonable trade-off.

      Improve the documentation of query output fields · d8a4b51d
      Iustin Pop authored
      The gnt-node and gnt-instance list commands have a customizable list of
      output fields, but the list is not up to date (in the man page) and not
      easily understandable from the ‘--help’ output.
      
      This patch updates the man pages and adds the available fields and
      default fields in the ‘--help’ output, as part of the description.
      
      Example:
      Usage
      =====
        gnt-node list
      
      Lists the nodes in the cluster. The available fields are (see the man page for
      details): name, pinst_cnt, pinst_list, sinst_cnt, sinst_list, pip, sip,
      dtotal, dfree, mtotal, mnode, mfree, bootid. The default field list is (in
      order): name, dtotal, dfree, mtotal, mnode, mfree, pinst_cnt, sinst_cnt.

      Add QA tests for gnt-instance modify · c0f74c55
      Iustin Pop authored
      This patch adds QA tests for most of the possible parameters in the
      instance modify operation (exception being the MAC), and modifies the
      sample QA file to run this test.
      
      It also tests the no-modification test, but that is a weak one: we only
      test that the exit code is one, not that the command gave a proper
      response ("... please give at least one parameter") as opposed to a
      traceback.

      Change the install directory for the tools · 909a0e4d
      Iustin Pop authored
      Currently, the tools are installed under $prefix/share/ganeti. This
      prevents installing other things in a nice way under share/ganeti (like
      arch-independent OS definitions), therefore we want the tools to live
      under share/ganeti/tools.
      
      A second change is that since these are programs, they would better live
      under libdir than datadir - we might have to change them later to
      binaries in which case 'share' is definitely not the way to go.
      
      This patch therefore changes the install directory for the tools to
      $prefix/lib/ganeti/tools.
