NAME

       rbd-nbd - map rbd images to nbd device

SYNOPSIS

       rbd-nbd [-c conf] [--nbds_max limit] [--read-only] [--device nbd device] map image-spec | snap-spec
       rbd-nbd unmap nbd device
       rbd-nbd list-mapped

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.
