Hi,
I'm running a samba CTDB setup using default Centos 7.2 repos, fully
up-to-date. This is in pre-production so this is quite a nasty problem.
Everything was running fine, including after a package update 1-2 days
ago. However, this morning I can't get winbind started, CTDB times it
out. I've taken the clustering=yes line out of smb.conf, and run winbind
at dedug level from the console. I get this:

*set_domain_online_request: called for domain IFA_NET**
**set_domain_online_request: domain IFA_NET was globally offline.
*What is this saying? This is a production domain (NT-style, not AD) and
is certainly online as otherwise I'd have 300 angry users. The smb.conf
has not changed for at least a week.
[root at metamora ~]# winbindd -V
Version 4.2.3
[root at metamora ~]# smbd -V
Version 4.2.3
Can anyone help me get this back on its feet?
Many thanks,
Alex
