【YashanDB】YAS-02147 the block 7-1-128 is corrupted

一、问题描述
YCM运维平台设置了自动备份任务，备份任务失败触发告警。

查看任务，报错提示：YAS-02147 the block 7-1-128 is corrupted

yasrman sys/yashan_123@x.x.x.x:1688 -c "backup database tag 'full_1' format 'full_bak_1'" -D /home/yashan/catalog
YAS-02147 the block 7-1-128 is corrupted

查看数据库日志

二、故障处理
1.查看表文件

SQL> select ID,NAME,BYTES/1024/1024 SIZE_MB,STATUS,AUTO_EXTEND from v$datafile where ID = 7;

          ID NAME                                                                 SIZE_MB STATUS    AUTO_EXTEND
------------ ---------------------------------------------------------------- ----------- --------- -----------
           7 +DG0/dbfiles/test1                                                         4 ONLINE    ON

1 row fetched.

2.查看

select OWNER,SEGMENT_NAME,SEGMENT_TYPE,TABLESPACE_NAME,BLOCK_ID,BYTES/1024/1024 size_mb,FILE_ID 
from dba_extents where BLOCK_ID=128;

3.验证表数据

4.尝试使用逻辑导出

5.备集群状态
