Pre-requisites:
|
|
|
|
|
1) have SeaweedFS master and volume servers running
|
|
|
|
|
2) have a "weed filer" running
|
|
|
|
|
These 2 requirements can be achieved with one command "weed server -filer=true"
|
|
|
|
|
|
|
|
|
|
This uses github.com/seaweedfs/fuse, which enables writing FUSE file systems on
|
|
|
|
|
Linux, and OS X.
|
|
|
|
|
|
|
|
|
|
On OS X, it requires OSXFUSE (http://osxfuse.github.com/).
