mydumper broken table detected, please review

There could be several reasons why a broken table is detected by

mydumper. Here are a few potential causes and suggested actions

to review:

1. Corrupted table data: If the table data is corrupted, it can lead to

a broken table detection. You should review the specific error

message provided by mydumper and consider running database

repair tools, such as myisamchk or innodb_force_recovery, to fix

the corrupted data.

2. Missing or mismatched table metadata: If the table metadata is

missing or doesn't match the actual table structure, mydumper may

detect it as a broken table. You should compare the table metadata

with the actual table structure in the database to identify any

inconsistencies. Restoring the correct metadata or recreating the

table may be necessary.

3. Insufficient privileges: Ensure that the user running mydumper

has sufficient privileges to access and dump the table. Lack of

necessary privileges can cause mydumper to incorrectly flag the

table as broken.

4. Incompatible table engine: mydumper might not support certain

table engines or features. Check if the broken table uses a table

engine that mydumper does not support, such as MEMORY or

MERGE. In such cases, you may need to convert the table to a

supported engine or exclude it from the mydumper backup.

5. Network or disk issues: If there are network or disk issues

during the backup process, it can result in incomplete or corrupted

table data, leading to broken table detection. Check for any

network or disk errors that might have occurred during the backup

and consider rerunning mydumper.

Remember, the specific error message provided by mydumper will

contain more detailed information about why the table is detected

as broken. Reviewing the error message and considering the

suggested actions will help you resolve the issue.
