Title:
keepalived fails to start when PID file is empty
Status in neutron:
New
Status in keepalived package in Ubuntu:
Fix Released
Bug description:
After a crash of a network node, we were left with empty PID files for
some keepalived processes:
root@network-node14:~# ls -l
/var/lib/neutron/ha_confs/0ab5f647-1e04-4345-ae9b-ee66c6f08882.pid
-rw-r--r-- 1 root root 0 May 19 08:41
/var/lib/neutron/ha_confs/0ab5f647-1e04-4345-ae9b-ee66c6f08882.pid
This causes the L3 agent to log the following errors repeating every
minute:
