虚拟机RAC的ASM磁盘组坏块导致重建DB

2011.11.23虚拟机RAC的ASM磁盘组坏块导致重建DB
刚刚在公司的一台PC机器上用vmware workstation8搭建了一套10gr2的rac环境，用的是裸设备+ASM搭建，在安装成功后，不小心被直接重启了下主机，结果再次启动虚拟机的时候提示到有磁盘损坏，也没有在意。但是在启动RAC的时候出现了问题，一开始的现象是如下几个个资源没办法随着其他资源一起启动：
ora.node1.LISTENER_NODE1.lsnr
ora.node2.LISTENER_NODE2.lsnr
ora.RAC.RAC1.inst
ora.RAC.RAC2.inst
ora.RAC.db
看具体的启动过程：

从下面2段内容可以看到asm在mount diskgroup的时候出现错误了：

没辙了，好在是测试环境，重建吧：
先dbca卸载DB，然后重建diskgroup，最后重建db。
在两个在节点上root用户操作，注意raw3和raw4是要创建磁盘组的设备：
dd if=/dev/zero of=/dev/raw/raw3 bs=1024 count=4
dd if=/dev/zero of=/dev/raw/raw4 bs=1024 count=4
接着重建磁盘组：
SQL> column header_status format a15;
SQL> column path format a30;
SQL> select header_status,path from v$asm_disk;


HEADER_STATUS PATH
--------------- ------------------------------
CANDIDATE /dev/raw/raw3
CANDIDATE /dev/raw/raw4
UNKNOWN ORCL:VOL2
FOREIGN /dev/raw/raw1
UNKNOWN ORCL:VOL1
FOREIGN /dev/raw/raw2


6 rows selected.


SQL> create diskgroup datadisk1 external redundancy disk '/dev/raw/raw3' name d1 disk '/dev/raw/raw4' name d2;


Diskgroup created.
最后重新dbca重建db。
重建之后，重启了虚拟机和主机几把，还有再次发现问题，ok。
