【RAC】處理VIP資源被佔用導致Cluster叢集軟體無法正常部署問題

kingsql發表於2014-09-30
  以刪除檔案的方式手工刪除RAC後，重新安裝RAC的Cluster軟體時，遇到如vip資源被佔用的問題，將問題現象、原因及處理方法記錄在此。

1.報錯截圖
錯圖提示如下圖所示。
【RAC】處理VIP資源被佔用導致Cluster叢集軟體無法正常部署問題

2.報錯內容
The virtual hostname(s), rac1-vip, you have specified appears to be already assigned to another system on the network. Please ensure that the virtual hostname(s) that you use for each of the nodes in the cluster are not in use currently.

3.報錯原因
錯誤提示描述得比較清楚，是由於vip資源仍然被佔用導致的。
這與我環境清理的方法有關，為了快速的刪除RAC環境，我這裡僅使用了刪除檔案的方法進行環境清理。因此此時的vip資源並沒有得到有效的釋放。這可以從網路卡資訊上得到印證。

上面的“eth0:1”便是vip資源。此時表明vip資源並沒有得到有效的釋放。

4.處理方法
為了有效地釋放vip以及其他資源，這裡我選擇了重啟作業系統方法。因為RAC環境對應的檔案已經被有效的清理，因此在作業系統重啟後vip資源自然也隨之清除。
作業系統重啟後網路卡資訊。

vip對應的資訊已經消失。
重新安裝Cluster叢集軟體不在出現報錯資訊。

5.小結
  在清理RAC環境後不要急於重新部署RAC環境。確保所有資源均有效釋放後再重新安裝是為妥當。

Good luck.
