MyISAM is a standard storage engine used for MySQL that is based on older ISAM code. A MyISAM table is made of three files: .frm, .MYI and .MYD. MYI (MYIndex) is the index file that MyISAM uses to store table indexes. But at times, you observe that system is unable to open the .MYI file. The most likely reason behind such behavior can be .MYI file corruption. As a result, you can’t access the database and hence need to restore lost information from backup. In such situations, if you find your database backup as invalid or incomplete or the backup is non-existent,
MySQL Database Recovery applications can be used for repairing and restoring the database.
You might receive the below error message with your MyISAM table:
“can't find file:
.MYI”
Here, ‘tablename’ refers to the name of affected MyISAM table.
Cause
The index file (.MYI) of table is damaged or corrupted. It can get corrupt due to unexpected shutdown, improper locking of table, errors in MyISAM code, network errors, hard disk issues and similar other reasons.
Solution
To rectify the above issue, you need to perform these steps in order:
• First, you need to check the database table for corruption using one of the following commands with valid options:
CHECK TABLE tablename
myisamchk *.MYI
mysqlcheck *.MYI
• If the above commands detect corruption, you need to repair the database. To accomplish the same, you can use following command:
REPAIR TABLE tablename
myisamchk *.MYI
mysqlcheck *.MYI
Before you try to repair the table, it is recommended to take its backup.
• If you still receive the same corruption error messages, you should delete the damaged database table and restore the lost data from latest backup. But if you observe that database backup is not up to the mark, you need to use MySQL Recovery tools.
