I believe it has, however I can't directly check because "ceph health"
starts to hang when I down the second node.

I've done this, however the behavior is the same:
$ for f in `ceph osd lspools | sed 's/[0-9]//g' | sed 's/,//g'`; do ceph
osd pool set $f min_size 1; done
set pool 0 min_size to 1
set pool 1 min_size to 1
set pool 2 min_size to 1
set pool 3 min_size to 1
set pool 4 min_size to 1
set pool 5 min_size to 1
set pool 6 min_size to 1
set pool 7 min_size to 1

And all writes block until I bring back an OSD.
