Hi all, Back in 2002 I opened a discussion on the samba-technical mailing list regarding the WinNT FILE_ATTRIBUTE_OFFLINE ( http://lists.samba.org/archive/samba-technical/2002-April/020969.html). Meanwhile some FILE_ATTRIBUTE_OFFLINE handling was implemented in the 'trunk' Samba. Currently (Samba 3.0.28a-1ubuntu4.4) provides the 'dmapi support' option for representing the mentioned attribute. Unfortun...

My goal is to use the Offline file attribute of Windows when sharing with Samba: https://docs.microsoft.com/en-us/dotnet/api/system.io.fileattributes?redirectedfrom=MSDN&view=netframework-4.7.2 It works when I share ZFS filesystem using the native ZFS CIFS sharing, but it fails when I share the same ZFS with Samba, that is the Offline files are not showed in Windows Client Il 3/4/2019

Hello, Does Samba support XAT_OFFLINE and XAT_ONLINE extended attribute? I have enabled "ea support = yes" but it seems to have no effect on that. Thanks Andrea

As far as I can tell this code just returns the 16-bit dos attributes field as defined in the protocol, so it should just return the FILE_ATTRIBUTE_OFFLINE in the returned bits (even if it's not listed in the SMB_DOS_MODE_XXX) definitions.

I made a small change to source3/smbd/dosmode.c to let my plugin on my linux box return FILE_ATTRIBUTE_OFFLINE for directories, and so far Windows (2008) seems okay with it. It displays the folder icon with the "X" over it and it navigates the folder hierarchy without trouble (so far). I can see that the SMB_VFS_IS_OFFLINE code went in originally for DMAPI support (Bokovoy, Jan 2008, commit d...

...o external storage, and to cope with reads/writes against it. Look at the VFS module source3/modules/vfs_tsmsm.c which, as decribed, is: Samba VFS module for handling offline files with Tivoli Storage Manager Space Management You would need to create a similar VFS module on ZFS to expose the FILE_ATTRIBUTE_OFFLINE flag to the client. Mostly it'll be wrapping the [f]get_dos_attributes() VFS calls. A bit fiddly, but doable (especially by companies used to Samba coding internals). Jeremy.

...r XAT_OFFLINE or XAT_ONLINE doesn't return anything. Yeh, my Googlefu is better than somebody who works for Google ;-) It seems to be something to do with ZFS on illumos: https://github.com/openzfs/openzfs/blob/master/usr/src/uts/common/fs/xattr.c Rowland > > Do you mean the Windows FILE_ATTRIBUTE_OFFLINE attribute ? > > If so, yes, we support that if the server is using dmapi. >
