NAME

mount.glusterfs - script to mount native GlusterFS volume

SYNOPSIS

mount -t glusterfs [-o <options>] <volumeserver>:/<volume>[/<subdir>] <mountpoint>

<server3>,..<serverN>:/<volname>[/<subdir>] <mount_point>

DESCRIPTION

This tool is part of glusterfs(8) package, which is used to mount using GlusterFS native binary.

mount.glusterfs is meant to be used by the mount(8) command for mounting native GlusterFS client. This subcommand, however, can also be used as a standalone command with limited functionality.
