Cinder 服務啟動

1. 啟動並設定開機自動啟動 openstack-cinder-scheduler, openstack-cinder-api 及 openstack-cinder-volume 服務。
   

   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-scheduler start
   Starting openstack-cinder-scheduler:               [  OK  ]
   [root@kvm4 ~(keystone_admin)]# chkconfig openstack-cinder-scheduler on
   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-api start
   Starting openstack-cinder-api:                     [  OK  ]
   [root@kvm4 ~(keystone_admin)]# chkconfig openstack-cinder-api on
   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-volume start
   Starting openstack-cinder-volume:                  [  OK  ]
   [root@kvm4 ~(keystone_admin)]# chkconfig openstack-cinder-volume on
   

2. 查看 cinder 服務的錯誤訊息。
   

   [root@kvm4 ~(keystone_admin)]# tail /var/log/cinder/*
   ==> /var/log/cinder/api.log <==
   
   ==> /var/log/cinder/cinder-manage.log <==
   
   ==> /var/log/cinder/scheduler.log <==
   
   ==> /var/log/cinder/volume.log <==
       self.driver.check_for_setup_error()
     File "/usr/lib/python2.6/site-packages/cinder/volume/drivers/lvm.py", line 76, in check_for_setup_error
       run_as_root=True)
     File "/usr/lib/python2.6/site-packages/cinder/utils.py", line 190, in execute
       cmd=' '.join(cmd))
   ProcessExecutionError: Unexpected error while running command.
   Command: sudo cinder-rootwrap /etc/cinder/rootwrap.conf vgs --noheadings -o name
   Exit code: 1
   Stdout: ”
   Stderr: 'sudo: sorry, you must have a tty to run sudo\n'
   

3. 以上錯誤訊息為用戶 cinder 無法使用 sudo 執行 cinder-rootwrap，必須 visudo 增加其權限。
   

   [root@kvm4 ~(keystone_admin)]# visudo
   Defaults:cinder !requiretty
   cinder ALL = (root) NOPASSWD: /usr/bin/cinder-rootwrap /etc/cinder/rootwrap.conf *
   

4. 其實 cinder, nova, quantum 等套件安裝時，已將必須以 sudo 執行的命令權限寫在 /etc/sudoers.d 目錄下，但因 /etc/sudoers 沒有將此目錄包含進去，造成執行失敗。執行 visudo 在最後面加入 #includedir /etc/sudoers.d，注意最前面的符號 #不是註解，一定要存在。
   

   [root@kvm4 ~(keystone_admin)]# ll /etc/sudoers.d/
   total 12
   -r--r-----. 1 root root 111 Jan 25 15:36 cinder
   
   [root@kvm4 ~(keystone_admin)]# visudo
   [root@kvm4 ~(keystone_admin)]# grep includedir /etc/sudoers
   #includedir /etc/sudoers.d
   

5. 刪除紀錄檔，再重新啟動 openstack-cinder-scheduler, openstack-cinder-api 及 openstack-cinder-volume 服務。
   

   [root@kvm4 ~(keystone_admin)]# rm -f /var/log/cinder/*
   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-scheduler restart
   Stopping openstack-cinder-scheduler:               [  OK  ]
   Starting openstack-cinder-scheduler:               [  OK  ]
   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-api restart
   Stopping openstack-cinder-api:                     [  OK  ]
   Starting openstack-cinder-api:                     [  OK  ]
   [root@kvm4 ~(keystone_admin)]# /etc/init.d/openstack-cinder-volume restart
   Stopping openstack-cinder-volume:                  [FAILED]
   Starting openstack-cinder-volume:                  [  OK  ]
   

6. 再查看 cinder 服務的紀錄，已無錯誤訊息。
   

   [root@kvm4 ~(keystone_admin)]# tail /var/log/cinder/*
   ==> /var/log/cinder/api.log <==
   
   ==> /var/log/cinder/scheduler.log <==
   2014-01-25 06:07:01 CRITICAL [cinder] need more than 0 values to unpack
   
   ==> /var/log/cinder/volume.log <==
   

7. 編輯 /etc/tgt/targets.conf，設定 ISCSI 包含 cinder volumes。
   

   [root@kvm4 ~(keystone_admin)]# echo 'include /etc/cinder/volumes/*' >> /etc/tgt/targets.conf
   

8. 啟動 tgtd 服務，並設定開機自動啟動。
   

   [root@kvm4 ~(keystone_admin)]# /etc/init.d/tgtd start
   Starting SCSI target daemon:                       [  OK  ]
   [root@kvm4 ~(keystone_admin)]# chkconfig tgtd on
   

9. 檢查是否有錯？
   

   [root@kvm4 ~(keystone_admin)]# tail /var/log/messages 
   Jan 25 06:53:36 kvm4 tgtd: semkey 0x6102fbaf
   Jan 25 06:53:36 kvm4 tgtd: tgtd daemon started, pid:24650
   Jan 25 06:53:36 kvm4 tgtd: tgtd logger started, pid:24653 debug:0
   Jan 25 06:53:36 kvm4 tgtd: work_timer_start(146) use timer_fd based scheduler
   Jan 25 06:53:36 kvm4 tgtd: bs_init(313) use signalfd notification
   

10. 檢查 openstack 服務的狀態。
    

    [root@kvm4 ~(keystone_admin)]# openstack-status
