vfs_crossrename

## Name

vfs_crossrename — server side rename files across filesystem boundaries

## Synopsis

`vfs objects = crossrename`

## DESCRIPTION

This VFS module is part of the samba(7) suite.

The `vfs_crossrename` VFS module allows server side rename operations even if source and target are on different physical devices. A "move" in Explorer is usually a rename operation if it is inside of a single share or device. Usually such a rename operation returns NT_STATUS_NOT_SAME_DEVICE and the client has to move the file by manual copy and delete operations. If the rename by copy is done by the server this can be much more efficient. vfs_crossrename tries to do this server-side cross-device rename operation. There are however limitations that this module currently does not solve:

This module is stackable.

## OPTIONS

crossrename:sizelimit = BYTES

  server-side cross-device-renames are only done for files if the filesize is not larger than the defined size in MiB to prevent timeouts. The default sizelimit is 20 (MiB)

## EXAMPLES

To add server-side cross-device renames inside of a share for all files sized up to 50MB:

            [testshare]
    	path = /data/mounts
    	vfs objects = crossrename
    	crossrename:sizelimit = 50

## VERSION

This man page is correct for version 3.6.0 of the Samba suite.
