This patch has been taken against SAMBA_3_0 Release 20028.
|
|
|
|
The patch basically moves the GPFS-ACL functionalities into the new GPFS VFS module( vfs_gpfs ).
|
|
|
|
Please read SAMBA_3_0/source/modules/README.nfs4acls.txt - generalised README file on Samba support for NFS4-ACLS.
|
|
This README file is specific for GPFS only.

Configuring GPFS ACL support
|
|
===============================
|
|
|
|
Binary: (default install path is [samba]/lib/vfs/)
|
|
- gpfs.so
|
|
|
|
Its compiled by default, no additional configure option needed.
|
|
|
|
To enable/use/load this module, include "vfs objects = gpfs" in the smb.conf file under concerned share-name.
|
|
|
|
Example of smb.conf:
|
|
|
|
[smbtest]
|
|
path = /gpfs-test
|
|
vfs objects = gpfs
|
|
nfs4: mode = special
|
|
nfs4: chown = yes
|
|
nfs4: acedup = merge
|
|
|
|
Adding "vfs objects = gpfs" to a share should be done only in case when NFS4 is really supported by the filesystem.
|
|
(Otherwise you may get performance loss.)

==================================================
|
|
Below are some limitations listed for this module:
|
|
==================================================
|
|
1. When a child file or child directory is created, the results are a bit different from windows as specified below:
|
|
|
|
Eg: Prent directory is set to have 2 ACES - full access for owner and everyone
|
|
|
|
Default ACL for Windows: 2 aces: allow ACE for owner and everyone
|
|
Default ACL for GPFS: 6 aces: allow and deny ACEs for owner, group and everyone
|
|
|
|
The below mentioned inheritance flags and its combinations are applied only to the owner ACE and not to everyone ACE
|
|
|
|
"fi"------>File Inherit
|
|
"di"------>Directory Inherit
|
|
"oi"------>Inherit Only
