FUSE-based client for ceph


ceph-fuse [-n client.username] [ -m monaddr:port ] mountpoint [ fuse options ]


ceph-fuse is a FUSE ("Filesystem in USErspace") client for Ceph distributed file system. It will mount a ceph file system specified via the -m option or described by ceph.conf (see below) at the specific mount point. See Mount CephFS using FUSE for detailed information.

The file system can be unmounted with:

fusermount -u mountpoint

or by sending SIGINT to the ceph-fuse process.


Any options not recognized by ceph-fuse will be passed on to libfuse.

-o opt,[opt...]

Mount options.

-c ceph.conf, --conf=ceph.conf

Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf to determine monitor addresses during startup.

-m monaddress[:port]

Connect to specified monitor (instead of looking through ceph.conf).

-n client.{cephx-username}

Pass the name of CephX user whose secret key is be to used for mounting.

--id <client-id>

Pass the name of CephX user whose secret key is be to used for mounting. --id takes just the ID of the client in contrast to -n. For example, --id 0 for using client.0.

-k <path-to-keyring>

Provide path to keyring; useful when it's absent in standard locations.

--client_mountpoint/-r root_directory

Use root_directory as the mounted root, rather than the full Ceph tree.


Foreground: do not daemonize after startup (run in foreground). Do not generate a pid file.


Run in foreground, send all log output to stderr and enable FUSE debugging (-o debug).


Disable multi-threaded operation.


Pass the name of Ceph FS to be mounted. Not passing this option mounts the default Ceph FS on the Ceph cluster.


ceph-fuse is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at https://docs.ceph.com for more information.
