VFS_BTRFS(8) System Administration tools VFS_BTRFS(8)NAME
vfs_btrfs - Utilize features provided by the Btrfs filesystem
SYNOPSIS
vfs objects = btrfs
DESCRIPTION
This VFS module is part of the samba(8) suite.
The vfs_btrfs VFS module exposes Btrfs specific features for use by
Samba.
Btrfs allows for multiple files to share the same on-disk data through
the use cloned ranges. When an SMB client issues a request to copy
duplicate data (via FSCTL_SRV_COPYCHUNK), this module maps the request
to a Btrfs clone range IOCTL, instead of performing reads and writes
required by a traditional copy. Doing so saves storage capacity and
greatly reduces disk IO.
This module is stackable.
CONFIGURATION
vfs_btrfs requires that the underlying share path is a Btrfs
filesystem.
