I'm running MySQL on my production servers here. "--version" says "mysql
Ver 14.7 Distrib 4.1.10a, for pc-linux-gnu (i686)". OS is RedHat
Enterprise ES version 4.

Over the weekend our /mysql partition filled up completely. I was able to
delete some unused databases, shut down mysql, move the data files to a
partition with more space, and restart mysql. I'm now trying to figure out
where all the disk space is going.

I can see the per-database directories, and it looks like the files in
those directories are believable sizes. Our largest customer database
directories are 295 MB, 95 MB, 67 MB, and 28 MB. In the /mysql dir itself,
though, is where the really big files live. We're looking at stuff like:
-rw-rw---- 1 mysql root 18874368 Nov 7 01:02 ibdata1

I'd like to figure out what's in those blasted bin files, and whether I
can get rid of them. Any pointers to where I can find that documented?
I've searched everyplace I can think of to look, but running on 2 hours
sleep in the last 2 days means I'm not firing on all cylinders :)
