Hello everybody,
I'd like to understand a strange behavior of a cluster of mine with,
basically, some IPAddr resource and a systemd resource that deals with
netfilter-persistent.
Here the configuration:
primitive FW-VIP-Outside IPaddr2 \
params ip=192.168.26.74 cidr_netmask=24 nic=outside arp_bg=true \
op monitor interval=20s timeout=20s
primitive FW-VIP-Private IPaddr2 \
params ip=192.168.104.100 cidr_netmask=24 nic=private arp_bg=true \
op monitor interval=20s timeout=20s
primitive Netfilter systemd:netfilter-persistent \
op start interval=0 timeout=60 \
op stop interval=0 timeout=60
group FW-VIPs FW-VIP-Private FW-VIP-Outside Netfilter
The active node, when I reboot the server, hangs shutting down for many
minutes writing:
A stop job is running for Pacemaker High Availability Cluster Manager (
11 s / 30 min). (where 11 is the number of seconds already passed)
Obviously switching to another master is immediate and performing
syetmctl stop netfilter-persistent is immediate too.
Do you have any hint on what goes wrong with this? I cannot find
anything strange in the logs.
Thanks a lot,
Roberto.
Is the netfilter systemd unit enabled outside pacemaker? Run
`systemctl is-enabled netfilter-persistent` to find out, and run
`systemctl disable netfilter-persistent` to disable it if it's
enabled. Only Pacemaker should start or stop netfilter.

Thank's a lot Reid,
Unfortunately it wasn't my case, netfilter-persistent seemed to be
disabled at boot.
Cheers,
R.
