NAME¶vfs_tsmsm - VFS module for handling offline files with Tivoli Storage Manager Space Management
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 ]
tsmsm:online ratio = [ number ]
tsmsm:dmapi attribute = [ attribute-name ]
tsmsm:dmapi value = [ value for the DMAPI attribute ]
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 part of version 4.9.5-Debian of the Samba suite.
AUTHOR¶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.
