Mirantis Fuel 9.0单控制节点的一个重要配置问题
by 陈亚峰 24 Dec '16

24 Dec '16

我们在使用Fuel 9.0部署M版OpenStack时，系统在正常运行数天后，总会出现控制节点失效，不得不重启整个环境的问题。使用brctl show 发现正常情况下的虚拟网桥接口全部消失不见了，如下： root@node-5:/var/log# brctl show bridge namebridge idSTP enabledinterfaces br-ex8000.9457a5565678noeno1.104 p_ff798dba-0 br-fw-admin8000.9457a5565678noeno1 p_eeee51a2-0 br-mgmt8000.3215d3e4d700noeno1.101 mgmt-conntrd br-storage8000.9457a5565678noeno1.102 经过查看neturon、upstart、nova、rabbitmq等组件的日志，均未解决问题，最终在pacemaker日志中发现如下错误： ec 08 03:20:50 [7126] node-5.domain.tld lrmd: notice: operation_finished:p_rabbitmq-server_notify_0:79939:stderr [ Error: rabbit

pengine: info: native_color:Resource sysinfo_node-5.domain.tld cannot run anywhere 可以看出pacemaker某些情况下认为节点健康度为负无穷，认为节点不可用，所有的资源无法找到可运行的节点，就停止掉了。关键信息是： Applying automated node health strategy: migrate-on-red 证明可能与节点健康策略有关，通过google搜索pacemaker migrate-on-red，发现配置成该选项后操作系统等出现的问题会被设置为负无穷，导致节点不可用，但实际情况是服务器仍可用，可能是硬件健康检查有一些告警，单节点情况下无节点切换，就整个当机了。修正错误方法： 1、登入控制节点 2、输入crm 进入 pacemaker控制台 3、输入configure进入配置界面 4、输入edit编辑，将property中的node health strategy设为none，如下： property cib-bootstrap-options: \ have-watchdog=false \ dc-version=1.1.14-70404b0 \ cluster-infrastructure=corosync \ cluster-recheck-interval=190s \ no-quorum-policy=ignore \ stonith-enabled=false \ start-failure-is-fatal=false \ symmetric-cluster=false \ last-lrm-refresh=1477747972 \ node-health-strategy=none

hi：请教个cinder的问题。使用本地的lvm做cinder的物理存储。猜测lvm相关的代码在cinder-8.0.0\cinder\volume\drivers\lvm.py里面。但是没有调用lvm的lvcreate命令: def _create_volume(self, name, size, lvm_type, mirror_count, vg=None): vg_ref = self.vg if vg is not None: vg_ref = vg vg_ref.create_volume(name, size, lvm_type, mirror_count) lvcreate是在nova目录下： [root@opentest stack]# vi ./nova/nova/virt/libvirt/storage/lvm.py from oslo_concurrency import processutils from oslo_log import log as logging from oslo_utils import units import six import nova.conf from nova import exception from nova.i18n import _ from nova.i18n import _LW from nova.virt.libvirt import utils CONF = nova.conf.CONF LOG = logging.getLogger(__name__) def create_volume(vg, lv, size, sparse=False): """Create LVM image. Creates a LVM image with given size. :param vg: existing volume group which should hold this image :param lv: name for this image (logical volume) :size: size of image in bytes :sparse: create sparse logical volume """ if sparse: preallocated_space = 64 * units.Mi check_size(vg, lv, preallocated_space) if free_space < size: LOG.warning(_LW('Volume group %(vg)s will not be able' ' to hold sparse volume %(lv)s.' ' Virtual volume size is %(size)d bytes,' ' but free space on volume group is' ' only %(free_space)db.'), {'vg': vg, 'free_space': free_space, 'size': size, 'lv': lv}) cmd = ('lvcreate', '-L', '%db' % preallocated_space, '--virtualsize', '%db' % size, '-n', lv, vg) 以及cinder的cinder\brick\local_dev]\lvm.py, brick的代码为什么不放在cinder\volume\drivers\lvm.py里面? def create_volume(self, name, size_str, lv_type='default', mirror_count=0): """Creates a logical volume on the object's VG. :param name: Name to use when creating Logical Volume :param size_str: Size to use when creating Logical Volume :param lv_type: Type of Volume (default or thin) :param mirror_count: Use LVM mirroring with specified count """ if lv_type == 'thin': pool_path = '%s/%s' % (self.vg_name, self.vg_thin_pool) cmd = LVM.LVM_CMD_PREFIX + ['lvcreate', '-T', '-V', size_str, '-n', name, pool_path] else: cmd = LVM.LVM_CMD_PREFIX + ['lvcreate', '-n', name, self.vg_name, '-L', size_str]
