Pre-requisites:
1) have SeaweedFS master and volume servers running
2014-05-13 13:57:23 +08:00
2) have a "weed filer" running
These 2 requirements can be achieved with one command "weed server -filer=true"
2018-12-30 02:31:36 +08:00
This uses github.com/seaweedfs/fuse, which enables writing FUSE file systems on
Linux, and OS X.
2014-05-13 13:57:23 +08:00
On OS X, it requires OSXFUSE (http://osxfuse.github.com/).
