univention-samba: /etc/init.d/smbd restart breaks samba-shares listener
Last modified: 2021-04-14 11:56:13 CEST
This is a special consequence of the general Bug #44237. I open it, because I hope we can at least implement a workaround in the samba-shares listener to avoid silent malfunction: If somebody manually runs /etc/init.d/smbd restart then systemctl looses track of the daemon and rates it as "dead". This causes subsequent /etc/init.d/samba reload calls to fail. The samba-shares listener relies on this reload to inform the smbd about configuration changes. We should try to implement a workaround in the samba-shares listener that detects this situation and takes suitable steps to recover, like running /etc/init.d/samba restart.
This is what the listener.log looks like in this situation: ====================================================================== 08.08.17 14:00:36.447 LISTENER ( PROCESS ) : updating 'cn=share01,cn=member01.foo.intranet,cn=shares,dc=foo,dc=intranet' command m UNIVENTION_DEBUG_BEGIN : uldap.__open host=master01.foo.intranet port=7389 base=dc=foo,dc=intranet UNIVENTION_DEBUG_END : uldap.__open host=master01.foo.intranet port=7389 base=dc=foo,dc=intranet Reloading samba configuration (via systemctl): samba.service.
