UsageLine: "mount -filer=localhost:8888 -dir=/some/dir",

Short: "mount weed filer to a directory as file system in userspace(FUSE)",

Long: `mount weed filer to userspace.

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 (https://osxfuse.github.io/).
|
|
|
|
RDMA Acceleration:
|
|
For ultra-fast reads, enable RDMA acceleration with an RDMA sidecar:
|
|
weed mount -filer=localhost:8888 -dir=/mnt/seaweedfs \
|
|
-rdma.enabled=true -rdma.sidecar=localhost:8081
|
|
|
|
RDMA Options:
|
|
-rdma.enabled=false Enable RDMA acceleration for reads
|
|
-rdma.sidecar="" RDMA sidecar address (required if enabled)
|
|
-rdma.fallback=true Fallback to HTTP when RDMA fails
|
|
-rdma.readOnly=false Use RDMA for reads only (writes use HTTP)
|
|
-rdma.maxConcurrent=64 Max concurrent RDMA operations
|
|
-rdma.timeoutMs=5000 RDMA operation timeout in milliseconds
|
|
|
