暂挂后，恢复时，两台机器分别重启

然后crs_stat失败，开始排错

1.         首先查看存储，发现openfiler中绿色扇区丢失。Fdisk看不到磁盘

2.         参考这个文档，将被异常排除的列注释掉

3.        

4.         重新扫描

iscsiadm -m node -T iqn.2006-01.com.openfiler:fra -p 10.0.0.3:3260 -l 

iscsiadm -m node -T iqn.2006-01.com.openfiler:ocr -p 10.0.0.3:3260 -l 

iscsiadm -m node -T iqn.2006-01.com.openfiler:data -p 10.0.0.3:3260 -l 

start_udev

fdisk -l

最后通过ll –l /dev/ora*来确认。（双机）

5.         虽然找到磁盘，但是报错

6.         添加文件

注意是tab键

[root@rac2 ocfs2]# vi cluster.conf

        ip_port = 7777

        ip_address = 172.16.5.230

        number = 0

        name = rac1

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 172.16.5.231

        number = 1

        name = rac2

        cluster = ocfs2

cluster:

        node_count = 2

        name = ocfs2
