[sheepdog-users] about status halted

[Valerio Pachera]

cluster with 4 nodes --copies 3.

Kill node 4 and wait the recovery to end.
Kill node 3, Cluster status: IO has halted as there are too few living nodes.

In my head :-) the cluster is "frozen".
Also 'node recovery' gives empty output.

Why is node 3 going the be recovered once back?

Nodes In Recovery:
  Id   Host:Port         V-Nodes       Zone
   2   192.168.2.43:7000      92  721594560

It seems like it's overwriting the chunks.
Is it possible to understand from sheep.log if chunks are
overwritten/added or "marked as good"?
