> Fsck doesn't count replicas that are on decommissioning nodes. If a block has all replicas
on the decommissioning nodes, it will be marked as missing, which is alarming for the admins,
although the system will replicate them before nodes are decommissioned.
> Fsck output should also show decommissioning replicas along with the live replicas.
