This is the case.

Please setup and run Chunkservers, as the minimum required number of CS to work with Masters HA is 3. MooseFS HA is full of protections, e.g. split-brain prevention. It bases on a voting mechanism, so Chunkservers vote on Leader election.

In order to have Leader in cluster, you have to have set up and connected at least an "integer half" + 1 of Chunkservers (so if you have 3, it must be 2, if you have 4 or 5, it must be 3, if you have 6 or 7 it must be 4 and so on).

Best regards,
Peter
