■問い合わせ内容
Server2台でクラスタを構成している。
仮にServer2をOS shutdownした状態ではVCSサービスは継続する。
この状況下でServer1がもしOS不具合でOSリスタートもしくは手動でOS停止してしまった場合に
Server1がOS起動完了してもVCSのサービスが起動しない。

この状況下でServer1のみでも各サービスグループを起動する(ONLINE化)方法、手順を知りたい。
※Server1でhastart -onenodeコマンドを実行して見たがサービス起動せず。

Hello,

Since you have a 2 node cluster, the GAB configuration file (/etc/gabtab) will contain GAB seeding for 2 nodes. If both the servers are rebooted, first server will come up & will keep waiting for GAB to seed on other node as well. If you want to force seed one node to start cluster services, you need to enter

# gabconfig -c -x     (this will force cluster services to start)

to answer your 3 questions

1. When one of server2 is down, but VCS service is still continue.

>> If both servers were up & running & then 1 server goes down, --- Then yes, server1 will keep running VCS

2. The rest of server1 restaerted, or rebooted when 1.

>> When server 2 was already down & you rebooted server 1 as well, then GAB will not start because it will expect both the nodes to be there as explained above. You need to force seed GAB as mentioned above in order to get GAB to start on server 1

3. After Server1 boot up and OS restarted. But VCS service cnannot start.

>> Answer in step 2 above.
