      Fix disk adoption interaction with ipolicy checks · ba147ff8
      Iustin Pop authored
      
      
      In Ganeti 2.6, disk adoption is broken due to the ipolicy checks being
      done before we read volume size from remote nodes. We fix this by
      simply moving these checks to after the disk adoption code which
      updates the disk size; it's not that nice that we fail a (almost)
      config-level check after we've reserved the LVs, etc., but we need to
      do so in order to validate the ipolicy correctly.
      
      Tested:
      
      - normal instance creation
      - creation via adoption with good size (pass)
      - creation via adoption with wrong LV size (fail as expected)
      - QA in progress

      Fix bug in non-mirrored instance allocation · 14b5d45f
      Iustin Pop authored
      
      
      The function `allocateOnSingle' has a bug in the calculation of the
      cluster score used for deciding which of the many target nodes to use
      in placing the instance: it uses the original node list for the score
      calculation.
      
      Due to this, since the original node list is the same for all target
      nodes, it means that basically `allocateOnSingle' returns the same
      score, no matter the target node, and hence the choosing of the node
      is arbitrary, instead of being done on the basis of the algorithm.
      
      This has gone uncaught until reported because the unittests only test
      1 allocation at a time on an empty cluster, and do not check the
      consistency of the score. I'll send separate patches on the master
      branch for adding more checks to prevent this in the future.

      Fix warnings/errors with newer pylint · 8ad0da1e
      Iustin Pop authored
      
      
      To help developing Ganeti on newer distributions, let's try to fix
      pylint warnings/errors. I'm using pylint from current Debian wheezy:
      pylint 0.25.1, astng 0.23.1, common 0.58.0, and we have 3 things that
      needs fixing.
      
      First, a really wide "except", with the silencing in the wrong
      place. I'm not sure why this doesn't have "except Exception", so let's
      add it. However, pylint still complains about "Catching too general
      exception", even though we do want to catch both system and our
      exception, so let's add a silence for W0703. It's true that we
      shouldn't catch KeyboardInterrupt and friends, but that should be
      cleaned up on the master branch.
      
      Second, pylint complains about "redefining name builtin tuple",
      because we do some pattern matching in the except blocks in
      netutils. This seems to be a false positive, but let's clean the code
      around this.
      
      And finally, type inference again goes bad, so let's silence E1103
      with its "boolean doesn't have 'get' method".
      
      After this, I can run "make lint", and by extension "make
      commit-check" on Debian Wheezy, yay! We might be able to bump our
      required pylint versions to something not ancient…

      Fix decorator uses which crash newer pylint · fc3f75dd
      Iustin Pop authored
      
      
      Pylint version:
      
        pylint 0.25.1,
        astng 0.23.1, common 0.58.0
      
      crashes when passing the fully-qualified decorator name with:
      
        File "/usr/lib/pymodules/python2.7/pylint/checkers/base.py", line 161, in visit_function
          if not redefined_by_decorator(node):
        File "/usr/lib/pymodules/python2.7/pylint/checkers/base.py", line 116, in redefined_by_decorator
          decorator.expr.name == node.name):
      AttributeError: 'Getattr' object has no attribute 'name'
      
      I found out that simply using a shortened name will 'fix' this issue,
      so let's do this to allow running newer pylint versions.

      Fix computation of disk sizes in _ComputeDiskSize · 6a3166cb
      Constantinos Venetsanopoulos authored
      
      
      Currently, hail fails with FailDisk when trying to add an instance
      of type: 'file', 'sharedfile' and 'rbd'.
      
      This is due to a "0" or None value in the corresponding dict inside
      _ComputeDiskSize, which results in a "O" or non Int value of the
      exported 'disk_space_total' parameter. This in turn makes hail fail,
      when trying to process the value:
      
       - with "Unable to read Int" if value is None (file)
       - with FailDisk if value is 0 (sharedfile, rbd)
      
      The latter happens because the 0 value doesn't match the instance's
      IPolicy, since it is lower than the minimum disk size.
      
      The second problem still exists when using adoption with 'plain'
      and 'blockdev' template and will be addressed in another commit.

      Add verification of RPC results in _WipeDisks · f08e5132
      Iustin Pop authored
      
      
      Due to an oversight, the pause/resume sync RPC calls in _WipeDisks
      lack the verification of the overall RPC status, and directly iterate
      over the payload. The code actually doing the wipe does verify
      correctly the results. This can result in jobs failing with a hard to
      diagnose:
      
      OpExecError ['NoneType' object is not iterable]
      
      instead of proper "RPC failed" message.
      
      This patch adds a hard check on the pause call, but for the resume
      call it just logs a warning if the RPC failed; the rationale being
      that if we can't contact the node for pausing the sync, it's likely
      wiping will fail too, but after the wipe has been done, we can
      continue.
