This is not a ctdb issue. ldb needs to be made ctdb-aware,
so that it can run its databases in a cluster. I am not
aware of anybody actively working on it, but to get a fully
HA AD DC as you have it in mind it is necessary.

It's very unlikely to happen.

Someone should have multiple AD DC's with replication,
instead of using a ctdb cluster.
Comment 2 Jonn Taylor 2013-01-27 16:02:10 UTC
Not sure I am explaining what needs to happen.

I want to have 2 AD DC's but with a common CTDB clustered file system for sharing files, not the DC part.

Then split the file server from the AD server, you could use LXC.
