原因

• NTPサーバとノードの時刻の差が1000ミリ秒、つまり1秒より大きい。たぶん。

対処

• ndptd を停止する。

[root@node01 CVU_11.2.0.2.0_grid]# service ntpd stop
Shutting down ntpd:                                        [  OK  ]

• 手動でNTPサーバと時刻同期する。

[root@node01 CVU_11.2.0.2.0_grid]# ntpdate 0.centos.pool.ntp.org
25 Dec 22:15:17 ntpdate[26682]: step time server 183.180.25.126 offset 3.206603 sec

• ntpd を開始する。

[root@node01 CVU_11.2.0.2.0_grid]# service ntpd start
ntpd: Synchronizing with time server:                      [  OK  ]
