ORA-01157: cannot identify/lock data file导致表空间无法online

朋友和我聊到一个案例,一个表空间本来有一个数据文件(已经有大量数据进入),然后他加入7个数据文件,这个时候他发现他加多了文件,想删除这些数据文件,可是又不怎么懂数据库,直接offline 表空间,然后rm掉相关数据文件,最后表空间无法online.我对其场景进行了模拟恢复测试,使用bbed和dul对其进行恢复

模拟场景
表空间有一个数据文件,里面有数据,然后加入一个新数据文件,进入offline tbs,然后rm数据文件
offline表空间后,该表空间存在的数据文件也会offline

ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01251: Unknown File Header Version read for file number 12
这个主要是块号和块地址不一匹配,导致数据库无法识别

ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01203: wrong incarnation of this file – wrong creation SCN
这个由于数据文件头的创建scn和控制文件以及file$中的记录不一致

ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01207: file is more recent than controlfile – old controlfile
这个由于正常数据文件online过,或者你构造文件头使用的scn大于需要构造文件在控制文件中记录的scn值

这里证明,在表空间不能online的情况下,dul处理类似故障很轻松(但是需要重建表空间,bbed处理的从原理上可以不重建表空间),当然如果涉及的对象很多,而丢失的文件很少,可能bbed也不失为一种很不错的选择.
另外补充:如果表空间丢失的文件包含数据,也可以通过类似bbed和dul方法处理:bbed 让表空间online之后需要考虑跳过丢失文件;dul处理完全相同

asm disk误设置pvid导致asm diskgroup无法mount恢复

有朋友找到我说他们把以前存储到AIX直连的存储切换为含光纤交换机的存储网络后,RAC无法启动,让我给予支持.通过分析是由于换链路之后开始磁盘顺序不对,维护人员对其asm disk 设置了pvid,导致asm 磁盘组无法正常mount,从而使得含votedisk的dg的asm disk无法正常访问,从而RAC的cssd进程无法启动,同样数据文件的磁盘组也无法mount,通过kfed修复成功,实现数据0丢失.

从这里可以看出来是由于RAC启动过程中无法获得votedisk使得其无法正常启动,通过分析日志找出来votedisk相关磁盘

2014-12-15 17:36:15.424:

从这里可以知道rhdisk4,5,6为votedisk对应磁盘,使用kfed查看磁盘头信息

由上述分析可以基本上确定是asm disk header 被破坏,进一步分析破坏原因

从这里基本上可以看出来,是由于磁盘头被重写了pvid,导致asm disk header 被破坏.进一步分析asm log,确定哪些磁盘被用作asm disk

这里可以确定asm disk为rhdisk[4-9],通过kfed分析全部和rhdisk4一样的问题,也符合lspv查询出来的结果,使用kfed repair修复asm disk header后

           4           0 /dev/rhdisk8

6 rows selected.

           1 ARCH

这里证明通过kfed对磁盘头的修复,asm磁盘组已经全部mount成功,GI状态也恢复正常

这里忽略了一个问题,在修复磁盘头之前没有清除pvid,导致磁盘头修复后,pvid依然存储在odm中

通过分析发现fba磁盘组中无任何记录,使用该磁盘组进行直接清除pvid测试

通过测试直接清除pvid asm 磁盘头依然工作正常,关闭GI,使用chdev清除hdisk[4-9]所有pvid,启动GI一切正常

至此设置pvid导致asm disk header损坏的asm 恢复正常,实现数据0丢失。
温馨提示:aix asm disk磁盘中不能设置pvid,否则将会导致asm disk header 损坏,无法正常mount
