初步分析：

ＣＲＳ出问题了，重新配置CRS？重新配置ＣＲＳ，然后重新配置节点？

从OCFS2文件系统入手：

rac1-> more /etc/ocfs2/cluster.conf

node:

        ip_port = 7777

        ip_address = 192.168.0.3

        number = 0

        name = rac1

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.0.4

        number = 1

        name = rac2

        cluster = ocfs2

cluster:

        node_count = 2

        name = ocfs2

rac2-> more /etc/ocfs2/cluster.conf

node:

        ip_port = 7777

        ip_address = 192.168.0.3

        number = 0

        name = rac1

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.0.4

        number = 1

        name = rac2

        cluster = ocfs2

cluster:

        node_count = 2

        name = ocfs2

两个节点没问题 ！继续排查。。。。

检查心跳：

[root@rac1 ~]# /etc/init.d/o2cb status

Module "configfs": Loaded

Filesystem "configfs": Mounted

Module "ocfs2_nodemanager": Loaded

Module "ocfs2_dlm": Loaded

Module "ocfs2_dlmfs": Loaded

Filesystem "ocfs2_dlmfs": Mounted

Checking O2CB cluster ocfs2: Online

  Heartbeat dead threshold: 61

  Network idle timeout: 10000

  Network keepalive delay: 5000

  Network reconnect delay: 2000

Checking O2CB heartbeat: Active

心跳也没问题 ！第2个节点同上！

使用命令对两个节点进行文件挂载：

mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs

重新检查CRS

rac1-> /u01/oracle/product/10.2.0/crs_1/bin/cluvfy stage -post crsinst -n rac1,rac2

Performing post-checks for cluster services setup

Check passed.

Checking existence of ONS node application (optional)

说明CRS运行正常了 ！

重新检查状态：

rac1->  crs_stat -t

Name           Type           Target    State     Host

------------------------------------------------------------

ora.dbvdb.db   application    ONLINE    UNKNOWN   rac1

ora....b1.inst application    ONLINE    OFFLINE

ora....b2.inst application    ONLINE    OFFLINE

ora....SM1.asm application    ONLINE    UNKNOWN   rac1

ora....C1.lsnr application    ONLINE    UNKNOWN   rac1

ora.rac1.gsd   application    ONLINE    UNKNOWN   rac1

ora....C2.lsnr application    ONLINE    UNKNOWN   rac2

ora.rac2.gsd   application    ONLINE    UNKNOWN   rac2

ora.rac2.ons   application    ONLINE    UNKNOWN   rac2

ora.rac2.vip   application    ONLINE    ONLINE    rac2

和起初的状态好像不太一样了。。。。。

对节点服务进行检查：

rac1-> srvctl status nodeapps -n rac1

VIP is running on node: rac1

GSD is not running on node: rac1

Listener is not running on node: rac1

ONS daemon is not running on node: rac1

服务依旧没有启动。难道ASM出现问题？下步考虑解决GSD服务启动问题。。。。

rac1-> srvctl start asm -n rac1

PRKS-1009 : Failed to start ASM instance "+ASM1" on node "rac1", [PRKS-1009 : Failed to start ASM instance "+ASM1" on node "rac1", [CRS-1028: Dependency analysis failed because of:

CRS-0223: Resource 'ora.rac1.ASM1.asm' has placement error.]]

  [PRKS-1009 : Failed to start ASM instance "+ASM1" on node "rac1", [CRS-1028: Dependency analysis failed because of:

CRS-0223: Resource 'ora.rac1.ASM1.asm' has placement error.]]

ASM手工启动不了啊？看来是ASM的问题，
