You can use the command 'i loc' to show all local variables.

I've taken a look at this PR, and I'm not sure quite what to do. As
you've seen, le@ is currently looking at Vinum bugs, but I'm not even
sure this is a Vinum bug; it could very well be growfs. There are
also undoubtedly bugs remaining in fsck. If you can find a spare disk
and install 4.9 on it, then use it to fsck this volume, the results
could be interesting.
