daos-fuse -- Create and manage a POSIX-like filesystem in DAOS

Given a mountpoint, a DAOS pool UUID, and a container name, this utility will create and/or open the specified container for use as a filesystem backing store.

Prerequisites

• The fuse userspace tools (yum install -y fuse)
• A running daos_server instance
• A DAOS pool uuid (e.g. as returned by dcmd pool create)

Install

go get github.com/daos-stack/go-daos/cmd/daos-fuse

Example usage

$ daos-fuse $HOME/daos-fuse 23605ee8-3172-4f0f-9305-38001a9332fd test &
$ ls -l $HOME/daos-fuse
 total 0
 drwxrwxr-x. 1 vagrant vagrant  0 Mar 12 04:47 bar
 -rw-rw-r--. 1 vagrant vagrant 29 Mar 12 04:47 baz
 drwxrwxr-x. 1 vagrant vagrant  0 Mar 12 04:47 foo
 -rw-rw-r--. 1 vagrant vagrant 58 Mar 12 04:47 qux
 $ fusermount -u $HOME/daos-fuse
 

Note that the correct way to shut down the filesystem is with the fusermount utility; this will ensure a clean shutdown of the fuse filesystem server.

The -debug flag will enable copious amounts of debug output, which may be useful for development.
