[Samba] Does CTDB run under LXC containers?

[Peter Steele]

We're transitioning from a VM based environment to one that uses LXC 
based containers running under CentOS 7. CTDB runs fine under our CentOS 
7 VMs. The same packages running under LXC however seem to have issues:

# systemctl start ctdb.service
Job for ctdb.service failed. See 'systemctl status ctdb.service' and 
'journalctl -xn' for details.

# systemctl status ctdb.service
ctdb.service - CTDB
    Loaded: loaded (/usr/lib/systemd/system/ctdb.service; disabled)

I haven't dug too deeply into this, but I was wondering if anyone has 
any experience with running CTDB inside an LXC container? I have a 
suspicion that this is the culprit.
