vfs_prealloc - preallocate matching files to a predetermined size
vfs objects =
This VFS module is part of the samba
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.
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
•M - BYTES is a number of
•G - BYTES is a number of
A process writes TIFF files to a Samba share, and the is known these files will
almost always be around 4 megabytes (4194304 bytes):
path = /data/frames
vfs objects = prealloc
prealloc:tiff = 4M
vfs_prealloc is not supported on all platforms and filesystems. Currently only
XFS filesystems on Linux and IRIX are supported.
This man page is correct for version 3.0.25 of the Samba suite.
The original Samba software and related utilities were created by Andrew
Tridgell. Samba is now developed by the Samba Team as an Open Source project
similar to the way the Linux kernel is developed.
