fsck修复危险性较大,建议先备份对应的分区(dd命令备份分区)然后再处理,有导致分区数据全部或者部分丢失的风险,如果超级块彻底损坏无法恢复,请联系我们，提供专业ORACLE数据库恢复技术支持

File #N is offline, but is part of an online tablespace

发表于 2016 年 11 月 1 日 由 惜分飞

在看一个客户的数据库恢复日志的时候发现类似警告(File #N is offline, but is part of an online tablespace.),以前没有注意,这次通过试验来重现该部分内容
创建表空间

Tablespace created.

SQL> alter tablespace  readonly add datafile '/home/oracle/.oradata/test/readonly02.dbf' size 128M;

写入数据

SQL> create table t_readonly tablespace readonly as select * from dba_objects;

Table created.

这里看到了我们期待的警告
File #7 is offline, but is part of an online tablespace.
data file 7: ‘/home/oracle/.oradata/test/readonly01.dbf’
Successfuly brought file #7 online.
File #8 is offline, but is part of an online tablespace.
data file 8: ‘/home/oracle/.oradata/test/readonly02.dbf’
Successfuly brought file #8 online.
结论：如果数据库的表空间之前是read only,然后resetlogs操作就会有类似提示(File #N is offline, but is part of an online tablespace).这样的整个恢复过程不影响read only表空间中的数据
