Innochecksum is a small undocumented (at least in the manual) utility that verifies the checksum of ibdata file pages. I stumbled across it the other day while wandering through the source tree. It has a small bug that prevents it from being able to check files larger than 4G. This patch fixes it in linux. Someone that knows more about large file support in different OSs please comment on the patch.

It lives in the extras folder in the MySQL source. Here is the credits comment:

/*
InnoDB offline file checksum utility. 85% of the code in this file
was taken wholesale fron the InnoDB codebase.

The final 15% was originally written by Mark Smith of Danga

I think as a community we need to make sure that tools like this are kept in the forge and actively developed. More on this when I have had some sleep.

When Jeremy left yahoo a lot of people were left wondering “who would be the next Jeremy?” some people thought it would be me. Since then I have been asked several times why I’m not going to take a turn in the ivory tower. Now that things are in place the secret can be let out. Jeremy’s startup Proven Scaling is not just Jeremy’s startup but our startup. We have decided to take our MySQL skills and apply them to the problems of several companies.

At the first ever MySQL Camp Proven Scaling is holding a session/BOF on replication. We want to hear what you like and don’t like about replication. What better to get conversation going but FREE BEER!

There is one tiny problem. We don’t know how much to buy or what kind. If you’re going to the camp help us out by putting your name and your favorite brew (brand and type) on the MySQL Replibeertion page.
