...e failover. Hmm, that node where above output was seen hat released and taken that very ip shortly before. And then released it again. The last point in time is the one where I saw the remaining connections: Feb 13 12:08:11 serverpnn1 ctdbd[85617]: ../../ctdb/server/eventscript.c:655 Running event releaseip with arguments team1 x.x.253.252 24 Feb 13 12:16:26 serverpnn1 ctdbd[85617]: ../../ctdb/server/eventscript.c:655 Running event takeip with arguments team1 x.x.253.252 24 Feb 13 12:27:50 serverpnn1 ctdbd[85617]: ../../ctdb/server/eventscript.c:655 Running event releaseip with arguments team1 x.x.253...

...n. So I checked the 10.interface script and found that gratarp is only done in the updateip case, but not in the takeip case. As we have extended that script with some (more) logging I can say that we never see updateip being called. We only see "monitor" and "takeip" and "releaseip". The thing is that takeip never sends the gratarp. Even in the most current ctdb it does not (see https://gitlab.com/samba-team/samba/-/blame/master/ctdb/config/events/legacy/10.interface.script?ref_type=heads#L137). So I am wondering why not?

...3:810 Feb 13 12:27:55 <nfsserver> ctdb-eventd[85619]: 10.interface: x.x.253.252:2049 x.x.253.177:814 ... The log (which I unfortunately do not have anymore) showed 405 of those "Sending a TCP RST" lines in a row which is more than the reported 394. This output is coming from the releaseip section in /etc/ctdb/events/legacy/10.interface, which calls kill_tcp_connections (in /etc/ctdb/functions) which calls the ctdb_killtcp utility to actually kill the connections. This happens inside a block_ip/unblock_ip guard that temporarily sets up a firewall rule to drop all incoming packages fo...
