IBM AIX Read-only file system案例一则

昨晚有朋友数据库出现问题，由于断电，导致数据库中断，重启后数据库无法启动。
挂接存储后，Oracle告警日志显示文件系统变为只读，提示信息类似如下：

Thu Feb 26 08:32:39 2009
Errors in file /opt/oracle/admin/orcl/udump/orcl_ora_103378.trc:
ORA-01110: data file 13: '/data/orcl_data06.dbf'
ORA-01114: IO error writing block to file 13 (block # 1)
ORA-27041: unable to open file
IBM AIX RISC System/6000 Error: 30: Read-only file system
Additional information: 3

Errors in file /opt/oracle/admin/orcl/udump/orcl_ora_103378.trc:
ORA-01110: data file 12: '/data/orcl_data05.dbf'
ORA-01114: IO error writing block to file 12 (block # 1)
ORA-27041: unable to open file
IBM AIX RISC System/6000 Error: 30: Read-only file system

这种情况通常都是硬件故障导致的，为了保护数据，文件系统或存储挂接时通过只读方式加载，如果能够确认数据没有问题，重新R/W加载就能够恢复正常。
