mysqldump failed on one table of testbbs database with error code 145 . It fail to open it’s index table . Probably the index file is corrupted.

# mysqldump –databases testbbs –single-transaction > testbbs.sql

mysqldump: Can’t get CREATE TABLE for table ‘test_events’ (Can’t open file: ‘test_events.MYI’. (errno: 145))

Do a check on the table with sql command “check table ” and repair it by “repair table”:

# mysql -u root -p testbbs

mysql> check table test_events
