Dear Brian and Gregory, Thanks for your information about samba of Ceph. I am trying to use a Ceph client to mount Ceph DFS(/mnt/cephfs/) and set up a samba server to share the mount point(/mnt/cephfs/) to Windows 2008 AD. (Yes, I would like to integrate Windows Active Directory with a samba server which is also a Ceph client) However, I encountered one problem while doing so......>< I cannot write or upload files via samba although the read function is OK. Originally, I think I can fix it by changing /etc/fstab/ settings like...... "monitor_IP:/    /mnt/cephfs/   Âbtrfs defaults,acl  Â1 2" But it's not working.......and I don't know how to solve this acl problem at all....... Brian said he is working on this. Does that mean I cannot just set up a samba server to share a Ceph mount point to Windows AD now? Maybe I have to wait until the function of re-export samba is finished? Thanks for your kindness to reply~~^^ 2011/6/1 Brian Chrisman <brchrisman@xxxxxxxxx> > > On Tue, May 31, 2011 at 9:17 AM, Gregory Farnum <gregf@xxxxxxxxxxxxxxx> wrote: > > On Sat, May 28, 2011 at 7:45 PM, Sylar Shen <kimulaaa@xxxxxxxxx> wrote: > >> Hi Gregory, > >> Thanks for your information very much! > >> By the way, the test of re-exporting NFS I did worked not bad. > >> And I am wondering since Ceph can re-export NFS, then can Ceph > >> re-export SAMBA that connects to windows? > > We don't have a samba re-export functionality, although you can just > > run samba on a Ceph mount if you like.
