Hi I'm encountering an error with some of my Windows clients when using CTDB and samba to access a GPFS hosted share. We see the following error all the time. [2011/03/14 12:31:16.549084, 1] modules/vfs_gpfs.c:1099(vfs_gpfs_ntimes) vfs_gpfs_ntimes: set GPFS ntimes failed -1 The copy continues but is slow. All the timestamps seem reasonable for the data copied. The GPFS version is 3.3.0-9 and samba is 3.5.6 compiled from source with config line. $ ./configure --with-ctdb=/usr/local/src/ctdb --w...

I am migrating the main file servers at work onto a new storage platform based on GPFS. I am using RHEL 5.6 with the samba3x packages (aka 3.5.4) recompiled to get the vfs_gpfs and tsmsm modules, with a couple of extra patches to vfs_gpfs module to bring it 3.5.8 level. It is running with ctdb against Windows AD 2008 R2 domain controllers with all the idmapping been held in the AD. In order to get robust and frankly usable quotas we are making extensive use of filesets (...

Hello, I am using the vfs_gpfs samba module to map ACLs through samba. It works fine on files, but directory ACLs are ignored. Ex: getfacl /sb/share/myplace/ file: sb/share/myplace/ owner: root group: root user::rwx user:afrankel:rwx group::--- mask::rwx other::--- When I try to access this folder in Windows, I get permission...

I think this is a recurrence of an old bug. Running Samba 3.5.4 with CTDB on GPFS 3.4.0.6 with the vfs_gpfs module using CentOS 5.6. It is a vanilla CentOS RPM's with the vfs_gpfs module a self compiled add on. Running with NFSv4 ACL's. Basically what happens is when a user saves a file in Office 2010 (no Office 2007 to test with) with Windows 7 on the Unix side the permissions on the file get s...

...through to the Windows attributes on the under lying file system. That is assuming that your GPFS file system is sufficiently recent to support Windows attributes. I did some experimentations with a Terminal Server 2008 and Terminal Server 2003 R2 client against a CTDB RHEL Samba 3.5.4 with a VFS_GPFS module loaded against GPFS 3.4.0.5 and indeed setting the hidden attribute using Windows shows no change when I do mmlsattr -L on the file. Turning the debug level up to 10 shows lots of errors of the form get_ea_dos_attributes: Badly formed DOSATTRIB on file ..... ndr_pull_error(2): Bad switch...

Urgh? I modified the FreeBSD kernel to allow all_xx_fd() calls on O_PATH descriptors and that seems make vfs_zfsacl to work fine. Not 100% tested but I could atleast view and modify the ACL on some stuff from a Windows client via Samba that way. I?m not sure I?ll be able to get them to implement this ?officially? though. Reading ACLs via an O_PATH-opened descriptor seems to be on the way of

And noticed samba is regularly tries to load libgpfs.so. This is done in gpfswrap_init() in lib/util/gpfswrap.c, which is used in vfs_gpfs.c (understandable) *and* in lib/util/debug.c.

Is the ?important" vfs objects parameter documented in a man page anywhere? It appears in the man pages of several vfs modules, but never fully documented that I could find. Apparently it once was from a now dead link https://www.samba.org/samba/docs/old/Samba3-HOWTO/smb.conf.5.html#VFSOBJECTS <https://www.samba.org/samba/docs/old/Samba3-HOWTO/smb.conf.5.html#VFSOBJECTS> .

...ction: The user is doing mainly reads, so does the "create" you mention also cover opening/reading files? If only _creation_ of files is suffering from that we probably have some other/further performance issue. We have gpfs, which does not offer a case-insensitive mode, neither does the vfs_gpfs module.

Hi Rob, on your Info for Version 3.0.25 you pointed out the VFS-Module GPFS for using features of the underlaying GPFS-Filesystem. Also the man-pages-3/vfs_gpfs.8.html points to that module, but I can't find it anywhere. We are using a GPFS 3.2 3-Node Samba Cluster (3.0.24/28) on Dell HW. We would be very glad if it is posible to get - Quota Recognition for our users (we use "max disc size" but thats not the answer), - Filesize reportin...
