Hi Lars,

I have writen a Howto in German für CTDB with GlusterFS BUT there is
still a problem. If you try to set the Filessystempermissions via
Windows it is not working. You can't delete any of the permissions. If
you wan't I can send it to you. I also writing a Howto for Samba CTDB
with a Corosync, Pacemaker and OCFS2 Cluster.
If you try it with Gluster please let me know, if the stting of the
Permissions via Windwos is working for you.

Stefan
