mysqlcheck 不会修复表 (errno: 2)

Question

I'm trying to repair some corrupted tables throught mysqlcheck command, but it returns the following "errno 2" error:

# mysqlcheck -u user -p --repair database
Enter password:
database.users                                OK
database.notes
Error    : Can't find file: 'notes' (errno: 2)
status   : Operation failed
...

I don't even need the information that was stored in that tables I can't repair, if only I could repair the tables without information it would be fine.

Do you happen to know if is there any way to repair the corrupted tables?

Answer 1

Worked for me:

Stop MySQL to free memory and get MySQL run memory parameter to put in the repair command:

myisamchk --sort_buffer_size=20M --key_buffer_size=5G --read_buffer_size=8M --write_buffer_size=8M -t DIR_WITH_SPACE -r PATH_TO_TABLE.MYI

DIR_WITH_SPACE has to store tmp file as big as MYI table file. If you don't specify it, it'll use the system tmp, beware of reaching full.

PATH_TO_TABLE.MYI is the MYI file of your table, in the MySQL data dir or elsewhere read/write place.

Then the mysqlcheck should be useless and table usable.
