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
