udev_start导致vip漂移(常见情况:rac在线加盘操作引起)

发表于 2023 年 5 月 13 日 由 惜分飞

客户对asm进行扩容,执行udev_start命令之后,所有的vip全部漂移,业务全部中断
20230513203654

优先恢复业务,把所有vip漂移回来

[grid@rac3 ~]$  srvctl relocate vip -i rac1 -n rac1 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac2 -n rac2 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac3 -n rac3 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac4 -n rac4 -f -v
VIP was relocated successfully.

vip恢复正常，业务也恢复正常
20230513203712

出现该问题的原因是由于udev_start命令引起网卡瞬间中断,从而使得vip发生漂移
20230513212316
查看ifcfg配置文件
20230513212440
引起该问题的原因是udev对网卡进行了操作,从而引起该问题,处理建议在对应的ifcfg文件中加上 HOTPLUG=”no” （pulbic,private和其他需要关注的网络）

Media Recovery failed with error 600
ORA-283 signalled during: ALTER DATABASE RECOVER    CONTINUE DEFAULT  ...
ALTER DATABASE RECOVER CANCEL 
ORA-1112 signalled during: ALTER DATABASE RECOVER CANCEL ...

根据上述报错信息可以确认报错的是一个index,而且非系统核心对象,可以通过allow 1 corruption方式进行恢复,并且open库成功

SQL> recover  datafile 1 allow 1 corruption;
Media recovery complete.
SQL> alter database open;

Database altered.

SQL> select owner,object_name,object_type from dba_objects where object_id=469884;

OWNER
--------------------------------------------------------------------------------
OBJECT_NAME
--------------------------------------------------------------------------------
OBJECT_TYPE
---------------------------------------------------------
SYSTEM
PK_XFF_SERVERS
INDEX

SQL> alter index system.PK_XFF_SERVERS rebuild online;

Index altered.

数据库完美恢复,数据0丢失,业务可以直接正常使用
