在服务器重新启动后，juju ceph处于错误状态。钩子失败：“配置更改”

Question

我10天前成功地建立了openstack。今天，我重新启动了服务，并得到了下一个：

ceph-mon/0                maintenance  executing  1/lxd/0  10.2.200.44 
hook failed: "config-changed"                       
ceph-mon/1                error        idle       3/lxd/0  10.2.200.49                        hook failed: "config-changed"
ceph-mon/2*               error        idle       2/lxd/1  10.2.200.47                        hook failed: "config-changed"

我试着调试这个问题并得到了跟踪：

root@juju-b8f983-1-lxd-0:/var/lib/juju/agents/unit-ceph-mon-0/charm# ./hooks/config-changed 
Traceback (most recent call last):
  File "./hooks/config-changed", line 725, in <module>
    hooks.execute(sys.argv)
  File "/var/lib/juju/agents/unit-ceph-mon-0/charm/hooks/charmhelpers/core/hookenv.py", line 798, in execute
    self._hooks[hook_name]()
  File "/var/lib/juju/agents/unit-ceph-mon-0/charm/hooks/charmhelpers/contrib/hardening/harden.py", line 79, in _harden_inner2
    return f(*args, **kwargs)
  File "./hooks/config-changed", line 187, in config_changed
    check_for_upgrade()
  File "./hooks/config-changed", line 113, in check_for_upgrade
    ceph.pretty_print_upgrade_paths()))
  File "lib/ceph/utils.py", line 2162, in pretty_print_upgrade_paths
    for key, value in UPGRADE_PATHS.iteritems()]
AttributeError: 'dict' object has no attribute 'iteritems'

你能帮我一下吗？问题的原因是什么？某些python版本错配？但是，在服务器重新启动之前，如果所有操作都很好的话，这是怎么可能的。

希望你能帮忙。

由于Python3兼容性补丁的发布，一个解决方案是升级ceph魅力。它很简单：

juju upgrade-charm --force-units ceph-mon
juju resolved ceph-mon
