vfs_prealloc
preallocate matching files to a predetermined size
vfs objects = prealloc
DESCRIPTION
This VFS module is part of the
samba
7 suite.
The vfs_prealloc VFS module preallocates
files to a specified size each time a new file is created. This
is useful in environments where files are of a predetermined
size will be written to a disk subsystem where extending file
allocations is expensive.
This module is stackable.
OPTIONS
prealloc:EXT = BYTES
Preallocate all files with the extension EXT to
the size specified by BYTES.
The following suffixes may be applied to BYTES:
K - BYTES is a number of kilobytes
M - BYTES is a number of megabytes
G - BYTES is a number of gigabytes
EXAMPLES
A process writes TIFF files to a Samba share, and the
is known these files will almost always be around 4 megabytes
(4194304 bytes):
/data/frames
prealloc
4M
CAVEATS
vfs_prealloc is not supported on all
platforms and filesystems. Currently only XFS filesystems on
Linux and IRIX are supported.
VERSION
