共享存储故障。
再次仔细分析日志
操作系统日志中,两个节点都发现问题了lpfc link down。目前定位为存储控制器硬件故障
节点2当时就挂了,
而节点1还咬牙坚持了20分钟,
直到节点2报:
Tue Mar 31 19:11:34 2015
NOTE: ASMB terminating
Errors in file /u01/app/oracle/diag/rdbms/netdb/netdb2/trace/netdb2_asmb_4203.trc:
ORA-15064: communication failure with ASM instance
ORA-03113: end-of-file on communication channel
节点1才
Tue Mar 31 19:12:34 2015
LMON is running too slowly and in the middle of reconfiguration.
LMON terminates the instance.
在trc中发现
4: waited for 'control file parallel write'
files=0x1, block#=0x3, requests=0x1
wait_id=13099634 seq_num=58238 snap_id=1
wait times: snap=0.000062 sec, exc=0.000062 sec, total=0.000062 sec
wait times: max=infinite
wait counts: calls=0 os=0
occurred after 58.515758 sec of elapsed time
个人认为 'control file parallel write'事件来源于IO,但并无OSWATCH等监控记录,而且个人能力所限无法继续追查下去,还望老师们加以指导。 |
