Hello,
I am having trouble with Haproxy using a configuration was previously worked
and am getting a very odd to me error
Jan 11 13:58:00 ca04vlhaproxy01 haproxy[16077]: [ALERT] 010/135800 (16077) :
Proxy 'graylog_back': unable to find required default_backend: '#002'.
graylog.cfg configuration file:
frontend graylog_back
description graylog log backend
bind :5040-5046,:4514,:5514
mode tcp
log global
option tcplog
default_backend graylog_back
backend graylog_back
description graylog log backend
mode tcp
timeout connect 5000
timeout server 5000
option httpchk HEAD /api/system/lbstatus HTTP/1.1
http-check send hdr Host graylog.agilitypr.internal
http-check expect ! rstatus ^5 # only 5xx is bad
#timeout check 2000 # optional setting defaults to inter value if unset
balance roundrobin
server graylog01 ca04vlgraylogweb01.agilitypr.internal check check-ssl port
443 verify required ca-file ca-certificates.crt fall 2 rise 2 inter 2000
server graylog02 ca04vlgraylogweb02.agilitypr.internal check check-ssl port
443 verify required ca-file ca-certificates.crt fall 2 rise 2 inter 2000
There are two things I don't understand,
1. Why the error is labeling the missing backend as #002
2. And why haproxy cannot find the backend that is in the same config file
as the respective frontend
haproxy -vv
