DESCRIPTION

rbd-nbd is a client for RADOS block device (rbd) images like rbd kernel module. It will map a rbd image to a nbd (Network Block Device) device, allowing access it as regular local block device.

OPTIONS

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

--nbds_max *limit*
Override the parameter of NBD kernel module when modprobe, used to limit the count of nbd device.

IMAGE AND SNAP SPECS

image-spec is [pool-name]/image-name
snap-spec  is [pool-name]/image-name@snap-name
 
 
The default for pool-name is "rbd". If an image name contains a slash character ('/'), pool-name is required.

AVAILABILITY

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