MySQL5.1 ibdata1 is damage and need to be repair before it could be use by it application, Please what tools can I use or is there any expert that can help me fix this. thanks
Hi ctistechnologies,
Ibdata1 contains all system tables (and for older MySQL versions will contain table data as well).
If the instance detects this file as corrupted and system data is broken you will likely need to recover from a backup.
If just some of the tables are corrupted then you can try “repair table”/“check table” on the affected tables. Considering that this is a MySQL 5.1 instance (reached EOL 10 years ago) likely the tables are on MyISAM and repairing them will cause data loss of the corrupted part of the table so you might as well prefer to recover from a backup.
