[Samba] Upgrading a ctdb cluster: samba not listening on TCP port 445

Hi all,

I try to update two clustered samba file servers. Right now samba 4.7.0 with ctdb is running on both of them. To update samba I stopped ctdb on one of the servers, and compiled and installed samba 4.7.1 with:

./configure --with-cluster-support --with-shared-modules=idmap_tdb2,idmap_ad,vfs_glusterfs --with-systemd

Trying to start ctdb on the updated server fails with " ctdb-eventd[19790]: 50.samba: samba not listening on TCP port 445" in the ctdb.log. Trying to update directly to 4.7.3 or 4.7.4 shows the same error message.

Removing the "clustered = yes" from the smb.conf file and starting smbd by hand works fine and the smbd process listens on port 445. Downgrading again to 4.7.0 worked without any problems and ctdb and smbd are running again without any problems, but this is only a temporary solution.

Any help in how to debug this problem will be appreciated.

Best regards,
