I'm trying to resurrect the some of the contents of a drive that
crashed. It was suggested that I get acquainted with fsdb so
I'm digging in and realize most of what I'm looking at doesn't
make a lot of sense.
root@max(~)# fsdb /dev/vinum/mirror
** /dev/vinum/mirror

So the file mysql/db.err uses inode 4317399 and there are 6
blocks associated with this file. How do I determine which
blocks those are and what their contents are?
Thanks.
