Oracle11gr2,dbca创建时使用asm,报ORA-17502报错

Question

今天在用oracle11gr2，dbca创建时使用asm，报ORA-17502报错，创建日志：
ORACLE instance started.
Total System Global Area 2221395968 bytes

CREATE DATABASE "test"

ORA-17502: ksfdcre:5 Failed to create file +DATA/test/control01.ctl
ORA-15081: failed to submit an I/O operation to a disk
检查下asm的磁盘确实是660权限：
[grid@dbs disks]$ ll
total 0
brw-rw---- 1 grid asmadmin 8, 17 Aug 30 10:53 OCR_VOTE01
brw-rw---- 1 grid asmadmin 8, 18 Aug 30 10:53 OCR_VOTE02
brw-rw---- 1 grid asmadmin 8, 19 Aug 30 10:53 OCR_VOTE03

diskgroup已经是mount状态，asm实例登录没问题：
SQL> select group_number,name,sector_size,block_size,allocation_unit_size,state,type,total_mb,free_mb from v$asm_diskgroup;
GROUP_NUMBER NAME SECTOR_SIZE BLOCK_SIZE ALLOCATION_UNIT_SIZE STATE TYPE TOTAL_MB FREE_MB
2 DATA 512 4096 1048576 MOUNTED NORMAL 29319 29139
1 ARCH 512 4096 1048576 MOUNTED EXTERN 9773 9721
数据库的版本号确实是11.2：
SQL> select group_number, name, compatibility, database_compatibility from v$asm_diskgroup;
GROUP_NUMBER NAME COMPATIBILITY DATABASE_COMPATIBILITY
1 ARCH 11.2.0.0.0 10.1.0.0.0
2 DATA 11.2.0.0.0 10.1.0.0.0
装asm的时候用的是grid用户，3个操作系统组的时候使用都是dba，装oracle时用的是oracle用户，2个操作系统组的时候使用也都是dba：
[grid@dbs disks]$ id grid
uid=501(grid) gid=501(oinstall) groups=501(oinstall),502(dba),503(oper),504(asmadmin),505(asmoper),506(asmdba)
[grid@dbs disks]$ id oracle
uid=500(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(oper),506(asmdba)
为什么会报ORA-17502错误？

Answer 1

[grid@dbs bin]$ /u01/app/grid/product/11.2.0/grid/bin/setasmgidwrap o=/u01/app/oracle/product/11.2.0/db_1/bin/oracle
[grid@dbs bin]$ ls -l /u01/app/oracle/product/11.2.0/db_1/bin/oracle
-r-xr-s--x 1 oracle dba 201096662 Aug 30 10:23 /u01/app/oracle/product/11.2.0/db_1/bin/oracle
但权限仍然不是
-rwsr-s--x
是不是在最初用grid装asm的时候，跟装oracle软件的时候，选的用户组有关系？装asm跟oracle软件时用的都是dba用户组。
我原来这是想在一个单机环境中，配置一个asm存储做测试用的。
