NAME

6       MogileFS::ReplicationPolicy::MultipleHosts -- default replication
7       policy
8

RULES

10       This policy tries to put files onto devices which are on different
11       hosts.  If you only have 1 host and 2 devices on that one host, it
12       obviously can't, so it'll grudgingly put it on the same host.  But if
13       you request a minimum replica count of 2 and have 3 devices, it'll put
14       2 copies on different hosts.  If you have 4 devices on 2 hosts, and
15       request a minima replica count of 3, you'll get 3 copies on different
16       devices, but two of those devices will be on the same host, and that's
17       considered acceptable, since you have "multiple hosts" covered at
18       least.
