[Samba] CTDB node stucks in " ctdb-eventd[13184]: 50.samba: samba not listening on TCP port 445"

[Benedikt Kaleß]

Hi everybody,

I just updated my ctdb node from Samba version
4.9.4-SerNet-Debian-11.stretch to Samba version
4.9.8-SerNet-Debian-13.stretch.

After restarting the sernet-samba-ctdbd service the node doesn't come
back and remains in state "UNHEALTHY".

I can find that in the syslog:

Do you have any hint for me?

Except the update I didn't change anything. There is no firewall on the
machine:

root at ctdb-<HOST>:~# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination        

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination        

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination   


Best regards

Bene
