Keepalived doesn't regain quorum when using tracked process due to a bug in high numbered pids
The upstream has already fixed in a patch release 2.0.20
https://serverfault.com/questions/993432/keepalived-doesnt-gain-quorum-when-tracked-process-comes-up
Could we please get the 2.0.20 released to 20.04 |
[Impact]
If a user is tracking a process with PID > 32767 keepalived will not be able to work as expected.
This bug was fixed upstream here: https://github.com/acassen/keepalived/commit/23a5b8113bf0b8ec4718443df0406882e8e4d831
[Test Plan]
Launch a Focal VM and run the following commands:
# install keepalived and nginx
$ apt install -y nginx keepalived
# configure keepalived to track the nginx process
$ cat << EOF > /etc/keepalived/keepalived.conf
global_defs {
enable_script_security
}
vrrp_track_process track_nginx {
process nginx
weight 10
delay 1
}
vrrp_instance lb {
interface enp5s0
state MASTER
priority 100
virtual_router_id 50
authentication {
auth_type PASS
auth_pass password
}
track_process {
track_nginx
}
virtual_ipaddress {
10.191.226.19
}
}
EOF
$ systemctl restart keepalived
# stop nginx process to loose quorum
$ systemctl stop nginx
$ journalctl -u keepalived | grep Quorum
Feb 07 20:13:04 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
# start nginx process to gain quorum
$ systemctl start nginx
$ pidof nginx
3282 3281
$ journalctl -u keepalived | grep Quorum
Feb 07 20:13:04 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
Feb 07 20:19:58 keepalived-debug Keepalived_vrrp[3346]: Quorum gained for tracked process track_nginx
# stop nginx process to loose quorum again
$ systemctl stop nginx
$ journalctl -u keepalived | grep Quorum
Feb 07 20:13:04 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
Feb 07 20:19:58 keepalived-debug Keepalived_vrrp[3346]: Quorum gained for tracked process track_nginx
Feb 07 20:21:39 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
# start nginx process forcing its PID to be > 32767
$ echo 32767 > /proc/sys/kernel/ns_last_pid; systemctl start nginx
$ pidof nginx
32773 32772
# quorum is not gained again
$ journalctl -u keepalived | grep Quorum
Feb 07 20:13:04 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
Feb 07 20:19:58 keepalived-debug Keepalived_vrrp[3346]: Quorum gained for tracked process track_nginx
Feb 07 20:21:39 keepalived-debug Keepalived_vrrp[3346]: Quorum lost for tracked process track_nginx
[Where problems could occur]
The upstream fix is quite straightforward but if a problem would occur it would be manifested in any tracking process feature in keepalived. Since keepalived is widely used in HA, this might be reflected in some specific setups using keepalived.

To make sure the bug is fixed we need to install the fixed keepalived package, then stop and start the nginx process (with PID > 32767). After that, the quorum will be lost again and then regained:
$ systemctl stop nginx
$ systemctl start nginx
$ pidof nginx
33505 33504
$ journalctl -u keepalived | grep Quorum
Feb 08 14:46:47 keepalived-debug2 Keepalived_vrrp[8079]: Quorum lost for tracked process track_nginx
