in drbd.conf, say
no-disk-drain, no-disk-flushes, no-md-flushes.
does not work in that setup, anyways,
that's where the "IO error" comes from.
which will catch the IO error, implicitly set the things given
as work around above, and retry with those flags disabled.
Though I recommend to stay away from 8.4.0 in production for now,
at least if you use its main feature (multiple volumes per connection),
it shows some serious misbehavior still.
Once 8.4.1 is released, that may be better,
but even what is tagged as 8.4.1rc1 is known to be broken.
