Got error -1 from storage engine

有个小朋友修复从库，但是start slave 后，报错信息如下

Could not execute Write_rows event on table hsfdssdb.mf_textannounce; Got error -1 from storage engine, Error_code: 1030; handler error No Error!; the event's master log mysql-bin.388557, end_log_pos 581281335

唉。。难受。。。看了下参数文件

innodb_force_recovery = 4

问题就在这了，注释掉以后，从库复制正常

可参考Bug #76922

5.5 官方对于innodb_force_recovery 的解释

innodb_force_recovery is 0 by default (normal startup without forced recovery). The permissible nonzero values for innodb_force_recovery are 1 to 6. A larger value includes the functionality of lesser values. For example, a value of 3 includes all of the functionality of values 1 and 2.

If you are able to dump your tables with an innodb_force_recovery value of 3 or less, then you are relatively safe that only some data on corrupt individual pages is lost. A value of 4 or greater is considered dangerous because data files can be permanently corrupted. A value of 6 is considered drastic because database pages are left in an obsolete state, which in turn may introduce more corruption into B-trees and other database structures.

As a safety measure, InnoDB prevents INSERT, UPDATE, or DELETE operations when innodb_force_recovery is greater than 0.

1 (SRV_FORCE_IGNORE_CORRUPT)

Lets the server run even if it detects a corrupt page. Tries to make SELECT * FROM tbl_name jump over corrupt index records and pages, which helps in dumping tables.

2 (SRV_FORCE_NO_BACKGROUND)

Prevents the master thread and any purge threads from running. If a crash would occur during the purge operation, this recovery value prevents it.

3 (SRV_FORCE_NO_TRX_UNDO)

Does not run transaction rollbacks after crash recovery.

4 (SRV_FORCE_NO_IBUF_MERGE)

Prevents insert buffer merge operations. If they would cause a crash, does not do them. Does not calculate table statistics. This value can permanently corrupt data files. After using this value, be prepared to drop and recreate all secondary indexes.

5 (SRV_FORCE_NO_UNDO_LOG_SCAN)

Does not look at undo logs when starting the database: InnoDB treats even incomplete transactions as committed. This value can permanently corrupt data files.

6 (SRV_FORCE_NO_LOG_REDO)

Does not do the redo log roll-forward in connection with recovery. This value can permanently corrupt data files. Leaves database pages in an obsolete state, which in turn may introduce more corruption into B-trees and other database structures.
