今天就跟大家聊聊有关kilo版云主机无法终止及无法创建该怎么处理,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
openstack页面无法创建也无法终止云主机
点击错误实例,找到它的id 03f0403f-74cd-4d88-b1fb-1d3f4ceaa9e4
猜测是cinder的问题,于是进cinder日志目录下,在所有日志中查找该ID,发现报错信息
# cd /var/log/cinder # grep 03f0403f-74cd-4d88-b1fb-1d3f4ceaa9e4 * # view api.log Caught error: [Errno [Errno 13] Permission denied: '/var/lock/cinder' Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/oslo_messaging/rpc/dispatcher.py", line 142, in _dispatch_and_reply executor_callback)) File "/usr/lib/python2.7/site-packages/oslo_messaging/rpc/dispatcher.py", line 186, in _dispatch executor_callback) File "/usr/lib/python2.7/site-packages/oslo_messaging/rpc/dispatcher.py", line 130, in _do_dispatch result = func(ctxt, **new_args) File "/usr/lib/python2.7/site-packages/osprofiler/profiler.py", line 105, in wrapper return f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/cinder/volume/manager.py", line 157, in ldo_inner1 return ldo_inner2(inst, context, volume_id, attachment_id, **kwargs) File "/usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py", line 439, in inner do_log=False, semaphores=semaphores, delay=delay): File "/usr/lib64/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py", line 395, in lock ext_lock.acquire(delay=delay) File "/usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py", line 194, in acquire fileutils.ensure_tree(basedir) File "/usr/lib/python2.7/site-packages/oslo_concurrency/openstack/common/fileutils.py", line 35, in ensure_tree os.makedirs(path) File "/usr/lib64/python2.7/os.py", line 157, in makedirs mkdir(name, mode) OSError: [Errno 13] Permission denied: '/var/lock/cinder' ] Permission denied
根据报错信息可以看到/var/lock/cinder目录权限不足,进入该目录,发现并没有cinder的目录。
[root@bdc212 ~]# cd /var/lock/ [root@bdc212 lock]# ls -lrt total 0 drwx------ 2 root root 40 Jul 13 08:16 lvm drwx------ 2 root root 60 Jul 13 08:16 iscsi drwxr-xr-x 2 root root 40 Jul 13 08:16 ppp drwxrwxr-x 2 root lock 40 Jul 13 08:16 lockdev -rw-r--r-- 1 root root 0 Jul 13 08:16 ceph-disk -rw-r--r-- 1 root root 0 Jul 13 08:16 kdump drwxr-xr-x 2 root root 80 Jul 13 10:09 subsys
于是手动创建目录
# mkdir cinder
再次终止实例,日志依旧报错
Caught error: [Errno [Errno 13] Permission denied: u'/var/lock/cinder/cinder-a0403e20-5cf6-4abd-a469-e166e2fd37d3-detach_volume'
修改目录的权限
# chown cinder:cinder cinder/
再次终止实例,发现成功终止,而且没有报错。
另外,发现之前创建失败的云硬盘也可以删除掉了。
openstack在创建和终止云主机的时候会在/var/lock/cinder目录下生成一个文件,在没有该目录,没有权限的情况下自然无法正常创建和终止云主机,同时也包括云硬盘的创建删除。
奇怪的现象
机器重启后, /var/lock/cinder 这个目录会消失了
所以为了避免重启之后缺少这个目录带来的影响,将创建改目录的命令写入到开机自动执行的文件中
# vi /etc/rc.local ... if [ ! -d /var/lock/cinder ] ; then mkdir /var/lock/cinder; chown -R cinder:cinder /var/lock/cinder; fi
修改添加可执行的权限
# cd /etc/rc.d/ # chmod 755 rc.local
