SHEEPDOG(8) System Manager's Manual SHEEPDOG(8)

NAME dog - Command line utility for the sheep daemon

SYNOPSIS dog <command> <subcommand> [options]

DESCRIPTION dog - Sheepdog is a distributed storage system for QEMU. It provides highly available block level storage volumes to virtual machines. Sheepdog supports advanced volume management features such as snapshot, cloning, and thin provisioning. The architecture of Sheepdog is fully symmetric; there is no central node such as a meta-data server.

       The server daemon is called sheep(8).  A command line utility is avail‐
       able via dog(8).  QEMU virtual machines use  the  sheep  daemon  via  a
       block driver available in qemu(1).

       For more information, run 'dog <command> <subcommand> --help'.
