After few hours of digging in the starter bash script /etc/init.d/haproxy we found that the problem lies outside it, it is seems in Fedora's systemctl at all, in the /etc/init.d/functions include used in the balancer starter.
How to workaround the problem of Haproxy reload? Just remove following line from the end of functions file:
"x$1" = xreload -o \
After removal script code will look like this:
if [ "$_use_systemctl" = "1" ]; thenAnd Haproxy starter script finally is:
if [ "x$1" = xstart -o \
"x$1" = xstop -o \
"x$1" = xrestart -o \
"x$1" = xtry-restart -o \
"x$1" = xforce-reload -o \
"x$1" = xcondrestart ] ; then
systemctl_redirect $0 $1
exit $?
fi
fi
#!/bin/shBut take in account, applying this workaround we are letting all output (echo ect) from the reload code to be printed out to a console where systemctl reload haproxy.service (or old-style service haproxy reload) will be invoked. The same actual for other services that used /etc/init.d/functions, in Fedora 17 case it's ipsec, network and few else.
