I need to correct myself: The Munin graphs were never set to track the
SAN volume where the old database lived. So when the graph goes from
"near-zero" to "lots", it's actually correct.

When I compare the correct graph, however, it's apparently that I/O
writes have, on average, doubled.

The new volume uses the same file system and block size as the old one.
