Hello, seems that there is the most exact and right what you mentioned, but in my case I run a pdc and bdc with samba and ctdb is not for the use of that. Only a memberserver or fileserver can be clusterd with ctdb. If glusterfs is just not working or doing the job for that I fall back to drbd with gfs2 or ocfs2.
