-defaultReplication does not work for webdav uploads

[Derkades]

Filer -defaultReplicaPlacement is not specified so it should use master setting (I think?)

Master command line is master ip=10.131.1.1 -defaultReplication=100 -mdir=/data -volumeSizeLimitMB=1000
For filer: filer -master="10.131.1.1:9333" -ip=10.131.1.1 -dataCenter=robin -defaultStoreDir=/data
Volume servers:
volume -mserver="10.131.1.1:9333" -ip="10.131.1.1" -port=8080 -dir=/data -dataCenter=robin -rack=server -max=20
volume -mserver="10.131.1.1:9333" -ip="10.131.2.1" -port=8080 -dir=/data -dataCenter=joshua -rack=pi -max=20

Steps:

• Clear all directories of master, filer, and volume servers
• Start everything
• Topology shows my two servers in two "data centers"
  
• Confirm volume servers are empty
  
• Upload a single file using webdav
  
• Check volume server interface again (the one in the same "data center" as filer). Now shows volumes
  
• Enter weed shell and run replication

  dexec master weed shell -master 10.131.1.1:9333 -filer 10.131.1.1:8888
  master: 10.131.1.1:9333 filer: 10.131.1.1:8888
  > lock
  > volume.fix.replication
  

  Nothing happens
• Set replication manually for a volume and try again

  > volume.configure.replication -volumeId 4 -replication 100
  > volume.fix.replication
  replicating volume 4 100 from 10.131.1.1:8080 to dataNode 10.131.2.1:8080 ...
  

  it works!

Am I misunderstanding how -defaultReplication works or is this a bug?

webdav data is uploaded to volume servers directly, and currently do not have replication options yet.
