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.
Comment 4 Volker Lendecke 2020-12-11 13:50:25 UTC
Closing as WONTFIX. For the AD DC there is the well-defined replication protocol. And as we recommend anyway to run DCs on machines or VMs separate from the file services, right now there is no direct need to make ldb cluster-aware.
