OpenStack Upgrade 測試

這篇超級古文，沒什麼參考價值，現在都使用 kolla 佈署跟升級 OpenStack，只是發現以前有記錄過程，所以搬上來

本文紀錄時間為2018/01/22，看看就好，不要太認真，之前被公司要求如何升版，所以才做這測試

測試從Mitaka手動升級到Newton

環境

OS: Ubuntu 14.04

OpenStack version: Mitaka

Node:

  • 1台 controller

  • 1台 compute

  • 1台 storage

All node

  1. 所有節點更新OS至ubuntu 16.04，安裝都選第一個選項跟Y

  2. 備份所有節點的config檔

  3. 備份資料庫(controller)

# mysqldump -u root -p –opt –add-drop-database –all-databases > mitaka-db-backup.sql

  • Enable the OpenStack repository

    # add-apt-repository cloud-archive:newton

備註

以下列出遇到的問題

  1. nova list噴錯:

    ClientException: Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
[Wed May 24 13:59:15.475574 2017] [wsgi:error] [pid 8013:tid 140130413639424] <class 'oslo_db.exception.DBError'> (HTTP 500) (Request-ID: req-d786ae6a-f413-4654-b8d8-0297a0c5f52b)

  2. LOG如果出現:DBError: (pymysql.err.InternalError) (1054, u“Unknown column 'XXXXXXXXXXX 'field list'”) 請重新sync db

    # su -s /bin/sh -c "xxxxx-manage db_sync" xxxxx

  3. 建立VM噴錯 因為compute上的nova-compute有問題，只要建立VM，nova-compute就會死掉:

    Failed to perform requested operation on instance "test", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].

  4. 無法進入dashboard，查看apache2 error.log

ImportError: cannot import name securitygrouprules 然後在controller輸入 openstack flavor list，出現下錯誤

Unable to establish connection to http://controller:8774/v2.1/3fa5fc21995f4bf2b2da8d3073d9b819/flavors/detail: HTTPConnectionPool(host='controller', port=8774): Max retries exceeded with url: /v2.1/3fa5fc21995f4bf2b2da8d3073d9b819/flavors/detail (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f613c181a90>: Failed to establish a new connection: [Errno 111] Connection refused',))

之後查看nova所有服務，發現狀態為dead，重啟後為active，但是再下一次openstack flavorlist或重整網頁，nova所有服務又死了
