then you have 2 systems writing to the same block device with no
coherency between them, which will corrupt the filesystem, and one
system or the other or both will eventually notice this, throw an error,
and go readonly (if you have errors=ro).

You'll need to do something like STONITH (shoot the other node in the
head) before the new node can safely take over.
