NAME


innochecksum - offline InnoDB file checksum utility

SYNOPSIS


innochecksum [options] file_name

DESCRIPTION


innochecksum prints checksums for InnoDB files. This tool reads an InnoDB tablespace file,
calculates the checksum for each page, compares the calculated checksum to the stored
checksum, and reports mismatches, which indicate damaged pages. It was originally
developed to speed up verifying the integrity of tablespace files after power outages but
can also be used after file copies. Because checksum mismatches will cause InnoDB to
deliberately shut down a running server, it can be preferable to use this tool rather than
waiting for a server in production usage to encounter the damaged pages. As of MySQL
5.6.16, innochecksum supports files greater than 2GB in size. Previously, innochecksum
only supported files up to 2GB in size.

innochecksum cannot be used on tablespace files that the server already has open. For such
files, you should use CHECK TABLE to check tables within the tablespace.

If checksum mismatches are found, you would normally restore the tablespace from backup or
start the server and attempt to use mysqldump to make a backup of the tables within the
tablespace.

Invoke innochecksum like this:

shell> innochecksum [options] file_name

innochecksum supports the following options. For options that refer to page numbers, the
numbers are zero-based.

· -c

Print a count of the number of pages in the file.

· -d

Debug mode; prints checksums for each page.

· -e num

End at this page number.

· -p num

Check only this page number.

· -s num

Start at this page number.

· -v

Verbose mode; print a progress indicator every five seconds.
