错误1: 检查环境时,no module named docker
pip install docker-compose
错误2:环境检查时,nova任务时报错TASK [nova : Ensuring config directories exist]
"The conditional check 'inventory_hostname in groups[item.value.group]' failed,The error appears to be in '/usr/share/kolla-ansible/ansible/roles/nova/tasks/config.yml': line 14
尝试清除缓存,重新执行
kolla-ansible destroy ./all-in-one --yes-i-really-really-mean-it
错误依然,查看kolla-ansible/ansible/roles/nova/tasks/config.yml,第14行的作用:创建neutron各服务的配置文件目录,查看/etc/kolla下自动启动的组件有相应文件夹及配置文件,因此手动创建
mkdir /etc/kolla/nova
touch /etc/kolla/nova/nova.conf
问题的根本原因是pip安装的kolla-ansible与克隆的代码的all-in-one不匹配
需要手动安装kolla-ansible
python kolla-ansible/setup.py install
错误3:在dashboard上创建实例报错,但是命令行可以创建
Error:Failed to perform requested operation on instance "test3", the instance has an error status: Please try again later [Error: Build of instance 5f875c14-2050-42c2-a749-09ec2162e68c aborted: Volume dfc5e50e-9034-4467-ab67-091362f18309 did not finish being created even after we waited 0 seconds or 1 attempts. And its status is error.].
查看nova日志
cat /var/log/kolla/nova/nova-compute.log
Instance failed block device setup: VolumeNotCreated
错误为存储卷没有创建,说明可能是cinder的问题
查看cinder日志
tail -f /var/log/kolla/cinder/cinder-volume.log
ERROR cinder.cmd.volume [-] Configuration for cinder-volume does not specify "enabled_backends". Using DEFAULT section to configure drivers is not supported since Ocata.
查看volume状态
openstack volume service list
cinder-backup\cinder-volume:down
发现cinder-volume服务的状态为:down,猜测问题的根本原因就在这里
解决方法:创建cinder-volumes卷组
1. dd if=/dev/zero of=./disk.img count=200 bs=512MB
2. losetup -f
3. losetup /dev/loop0 disk.img
4. pvcreate /dev/loop0
5. vgcreate cinder-volumes /dev/loop0
docker ps -a | grep nova | awk '{print $1}' | xargs docker restart
创建好卷组,重新部署,查看cinder-volume的状态为up
错误4:登录权限问题
使用命令行操作时,初次登陆操作会显示如下错误
Missing value auth-url required for auth plugin password
执行一下凭证文件
. /etc/kolla/admin-openrc.sh
错误5:glance连接ceph后创建镜像,状态一直是:queued,查看glance日志
ERROR glance.common.wsgi ObjectNotFound: [errno 2] error calling conf_read_file
创建镜像一直排队,说明数据无法写入,日志信息说明glance读取配置文件时出错了
修改配置文件后,日志中又出现其他错误,但是说明可以读到配置文件了:
1. glance_store._drivers.rbd ObjectNotFound: [errno 2] error connecting to the cluster
2. Failed to upload image data due to internal error: BackendException
错误显示glance无法连接cluster,猜测是由于ceph认证失败导致,
解决方法:
将/etc/ceph/ceph.client.admin.keyring拷入glance_api容器的/etc/ceph下
错误6:连接ceph,创建虚拟机之后,实例无法启动,显示:no bootable device
上传镜像的格式问题,需转为raw格式
错误7:更改挂载盘之后的问题
更改docker挂载盘之后,某些容器一直重启中,清除所有容器之后重新部署,某些容器还是一直重启中,猜测与镜像有关,执行下面命令,清除所有的镜像文件
docker rmi $(docker images -q)
重新载入镜像
docker load -i super.tar
重新执行部署
错误8:mariadb等待VIP超时
检查/etc/kolla/globals.yml文件,将kolla_internal_vip_address配置项注释掉
错误9:no module named decorate
需要升级包
pip install -U decorate
错误10: 安装openstack CLI客户端时
ERROR: Cannot uninstall 'pyOpenSSL',执行下面的命令进行安装
pip install python-openstackclient --ignore-installed pyOpenSSl
错误11: 环境检查时,gather facts卡顿很久
重启机器自然解决
错误12: 删除镜像失败,glance日志显示权限错误
原因:镜像中有一个snapshot,ceph对于snapshot是保护的,需要先删除snapshot,才能删除镜
错误13:生成密码时,报错:'module' object has no attribute '_ssl write_string'
根据提示检查cryptography是否安装了两个版本,彻底卸载重装
错误14:检查环境,check libvirt is not running
需要libvirt是关闭的状态
systemctl libvirtd stop
错误15:创建实例等待超时,查看日志:Stashed volume connector host is localhost.: BuildAbortException
猜测是卷组空间不足
# 查看卷组空间
vgs
1. dd if=/dev/zero of=./disk.img count=200 bs=512MB
2. losetup -f
3. losetup /dev/loop1 disk.img
4. pvcreate /dev/loop1
# 将新建pv扩展至已存在的卷组
5. vgextend cinder-volumes /dev/loop1
# 重启容器
docker ps -a | grep kolla | awk '{print $1}' | xargs docker restart
错误16:环境检查时的错误
ERROR! An unhandled exception occurred while templating '{{ neutron_tenant_network_types.replace(' ', '').split(',') | reject('equalto', '') | list }}'. Error was a , original message: no test named 'equalto'
解决方法:
pip install jinja2
