vfs_tsmsm - VFS module for handling offline files with Tivoli Storage Manager Space Management
SYNOPSIS
vfs objects = tsmsm
DESCRIPTION
This VFS module is part of the samba(7) suite.
The tsmsm VFS module is an extension for handling offline files with Tivoli Storage Manager Space Management.
It tries to avoid calling expensive DMAPI calls with some heuristics based on the fact that number of blocks reported of a file multiplied
by 512 will be bigger than 'online ratio' of actual size for online (non-migrated) files. If heuristic check fails, the module calls DMAPI
and asks for a specific attribute which is present for offline (migrated) files. If this attribute presents, the file is considered
offline.
This module is not stackable.
OPTIONS
tsmsm:hsm script = [ path to hsm script ]
hsm script should point to a shell script which accepts two arguments: operation and filepath. the tsmsm module only uses "offline" for
operation to set the file under filepath offline.
tsmsm:online ratio = [ number ]
Ratio to check reported size against actual file size. The default value is 0.5.
tsmsm:dmapi attribute = [ attribute-name ]
Name of a DMAPI attribute that is present when a file is offline. The default is "IBMobj" (which is what GPFS uses).
tsmsm:dmapi value = [ value for the DMAPI attribute ]
Value that the DMAPI attribute should have for the file to be considered offline. The default is empty (no value required).
EXAMPLES
A GPFS mount with TSM support can be exported via Samba as follows:
[gpfs_tsm_share]
vfs objects = tsmsm gpfs
path = /test/gpfs_mount
VERSION
This man page is correct for version 4.0 of the Samba suite.

VFS_PREALLOC(8) System Administration tools VFS_PREALLOC(8)NAME
vfs_prealloc - preallocate matching files to a predetermined size
SYNOPSIS
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:
o K - BYTES is a number of kilobytes
o M - BYTES is a number of megabytes
o 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):
[frames]
path = /data/frames
vfs objects = prealloc
prealloc:tiff = 4M
CAVEATS
vfs_prealloc is not supported on all platforms and filesystems. Currently only XFS filesystems on Linux and IRIX are supported.
VERSION
This man page is correct for version 3.0.25 of the Samba suite.

Hi,
Is there any command for showing offline users?
The only way I can think of doing it (as i cant find a command) is getting a list of all the online users, and comparing it to /etc/passwd, anything that is in /etc/passwd and not in the users file will be offline users. But I have no... (4 Replies)

So we taken the FS filesystem offline and followed the below steps.

Hello, I need to test whether our product will work with GPFS filesystems and I have some questions regarding the setup:
1. Do I need to dedicate an entire hard disk if I want to have GPFS on it? Or can I somehow split a disk into 2 virtual disks, and only use 1 for gpfs?
2. If lspv returns... (4 Replies)
