Cinder组件

作者:互联网

一、Cinder组件介绍

1、概念

cinder组件作用:

  1. 块存储服务,为运行实例提供稳定的数据块存储服务。
  2. 块存储服务,提供对 volume 从创建到删除整个生命周期的管理。

2、核心架构

3、核心组件

4、工作流程

二、常用操作

1、Volume管理

# 4.扩容
# 注意:可以从小改大,但是不可以从大改小。
# 注意:卷大小只能设置为整数值。

# 5.迁移
# 迁移一个卷到特定的主机,在请求体中指定 os-migrate_volume action。
# 一般不推荐对处于in-use状态,且挂载在多个虚机上的卷进行迁移。
# 默认只有管理员用户有迁移的权限,但是可以通过policy.json文件进行权限的设置。
cinder migrate <volume> <host>


2、Type管理

    type-create         Creates a volume type.   # 类型创建
    type-default        List the default volume type.
    type-delete         Deletes a volume type.   # 类型删除
    type-key            Sets or unsets extra_spec for a volume type.
    type-list           Lists available 'volume types'. (Admin only will see
                        private types)           # 类型列表查看
    type-show           Show volume type details.    # 类型详情查看
    type-update         Updates volume type name, description, and/or
                        is_public.               # 类型更新

# 查看类型
cinder type-list
[root@controller ~]# cinder type-list
+--------------------------------------+------+-------------+-----------+

+--------------------------------------+------+-------------+-----------+

# 创建类型
cinder type-create [ --description <description>, --is-public <is-public>]  <name>
    Positional arguments:
    <name>                Name of new volume type.

    Optional arguments:
    --description <description>
                            Description of new volume type.
    --is-public <is-public>
                            Make type accessible to the public (default true).

查询块存储服务日志,找到报错信息:

[root@controller cinder]# vi /var/log/cinder/scheduler.log
2021-11-13 20:54:38.708 1268 ERROR cinder.scheduler.flows.create_volume [req-afe87e8b-cc3a-4275-8e58-fb0034da8be7 0f217182b5af448c988f5464c706a337 386dbfcf77e444c7872e4e23d5829fcc - - -] 
Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;
volume:create: No valid host was found. No weighed hosts available

计算节点上查看openstack的组件服务状态:

[root@compute ~]# openstack-status
== Cinder services ==
openstack-cinder-api:                   inactive  (disabled on boot)
openstack-cinder-scheduler:             inactive  (disabled on boot)
openstack-cinder-volume:                active
openstack-cinder-backup:                inactive  (disabled on boot)

确保cinder显示active,正常启动。

本次错误原因:两个节点的系统时间不同,导致计算节点的openstack-cinder-volume服务down掉了。需要在计算节点做如下操作:

[root@compute ~]# ntpdate 192.168.16.10
13 Nov 21:00:18 ntpdate[3689]: step time server 192.168.16.10 offset -324038.658500 sec
[root@compute ~]# date
Sat Nov 13 21:00:21 EST 2021
[root@compute ~]# systemctl restart openstack-cinder-volume

执行如上操作后问题解决,可查看dashboard上的系统信息cinder-volume服务从down改为up,如下图所示:
blockchain

再创建云硬盘时状态改为availability:

[root@controller ~]# cinder create 1 --name test2

2、openstack平台重启虚拟机创建失败

计算节点服务down掉处理:

systemctl restart openstack-cinder-volume

systemctl restart openstack-nova-compute

service neutron-metadata-agent restart

service neutron-openvswitch-agent restart
