MogileFS::ReplicationPUseryContributedePerlRDplicationPolicy::MultipleHosts(3)

NAME
       MogileFS::ReplicationPolicy::MultipleHosts -- default replication
       policy

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