openstack排错之cinder排错

这里应对的是较为简单的openstack错误问题。

cinder

错误点：cinder.conf中的default中的my_ip 此处使用ip而非主机名
cinder.conf中的最后的lvm处，将卷组名搞错了

排查过程：
1、我们试一下，可以看见cinder列表，看不见明显错误。所以我们查看日志

[[email protected] ~]# cinder list
+----+--------+------+------+-------------+----------+-------------+
| ID | Status | Name | Size | Volume Type | Bootable | Attached to |
+----+--------+------+------+-------------+----------+-------------+
+----+--------+------+------+-------------+----------+-------------+

其他日志没有明显报错，只有volume有错 卷组有问题

tailf /var/log/cinder/volume.log 
日志信息如下，心跳节点关闭
2020-01-09 01:55:35.305 2029 ERROR cinder.service [-] Manager for service cinder-volume [email protected] is reporting problems, not sending heartbeat. Service will appear "down".
2020-01-09 01:55:45.311 2029 ERROR cinder.service [-] Manager for service cinder-volume [email protected] is reporting problems, not sending heartbeat. Service will appear "down".

2、遇到情况，我们首先查看ntp服务是否正常，未开则打开

[[email protected] ~]# systemctl status ntpd
● ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
   Active: inactive (dead)


[[email protected] ~]# systemctl restart ntpd
[[email protected] ~]# systemctl status ntpd
● ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2020-01-09 02:05:35 UTC; 2s ago
  Process: 5612 ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS (code=exited, status=0/SUCCESS)

   CGroup: /system.slice/ntpd.service
           └─5613 /usr/sbin/ntpd -u ntp:ntp -g

3、同步本地时间，发现时间已经同步。

[[email protected] ~]# ntpdate 127.0.0.1
 9 Jan 02:06:20 ntpdate[5722]: the NTP socket is in use, exiting
[[email protected] ~]# lsof -i:ntp
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
ntpd    5613  ntp   16u  IPv4  90941      0t0  UDP *:ntp 
ntpd    5613  ntp   17u  IPv6  90942      0t0  UDP *:ntp 
ntpd    5613  ntp   18u  IPv4  90947      0t0  UDP localhost:ntp 
ntpd    5613  ntp   19u  IPv4  90948      0t0  UDP host-10-0-0-104.openstacklocal:ntp 
ntpd    5613  ntp   20u  IPv6  90949      0t0  UDP localhost:ntp 
ntpd    5613  ntp   21u  IPv6  90950      0t0  UDP xiandian:ntp 
ntpd    5613  ntp   22u  IPv6  90951      0t0  UDP xiandian:ntp 

4、我们再来检查配置文件。

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
crudini --set /etc/cinder/cinder.conf DEFAULT my_ip $HOST_IP_NODE
crudini --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver
crudini --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes
crudini --set /etc/cinder/cinder.conf lvm iscsi_protocol iscsi
crudini --set /etc/cinder/cinder.conf lvm iscsi_helper lioadm
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
my_ip = localhost       ***********************此处的my_ip，不可以填主机          # my_ip =127.0.0.1
enabled_backends = lvm
glance_api_servers = http://xiandian:9292

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volume        ********************此处的卷组名错了，少了s         #volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

5、重启服务。

[[email protected] ~]# systemctl restart openstack-cinder-volume.service target.service
[[email protected] ~]# 

6、我们再次查看日志，确认一下。

2020-01-09 02:37:34.338 10322 INFO cinder.volume.manager [req-20457e21-a2ff-42ef-80cd-9ed18d433d2e - - - - -] Starting volume driver LVMVolumeDriver (3.0.0)

确认刚才问题已经修复。

7，我们尝试创建云硬盘，云硬盘可用！解决问题。
