weedfs]# curl http://localhost:9333/dir/assign?replication=00 2012/09/28 12:40:09 Saving file id sequence 40000 to /tmp/weed.seq {"count":1,"fid":"2,75319ebb0553","publicUrl":"10.1.3.81:8080","url":"localhost:8080"}

The following requests are requesting 2 volumes from 2 different servers in the same rack. However, there is only one server running. So it can not assign a writable volume as requested.

curl http://localhost:9333/dir/assign No more writable volumes!

curl http://localhost:9333/dir/assign?replication=01 No more writable volumes!

actually there are two volume node,

curl http://localhost:9333/dir/status
{"DataCenters":[{"Free":93,"Max":100,"Racks":[{"DataNodes":[{"Free":93,"Max":100,"PublicUrl":"10.1.3.81:8080","Url":"localhost:8080","Volumes":7}],"Free":93,"Max":100}]}],"Free":93,"Max":100,"layouts":[{"replication":"00","writables":[2,5,7,1,6,4,3]},{"replication":"01","writables":null}]}[

I am pretty certain there are only one volume node, from the console output and also from the master status.

In the status json object, each DataNode, which is the volume server, has a "Url" attribute. There is only one "Url" attribute in the status output.
