Hello!
I have configured LVS Cluster with 2 LVS nodes, 4 Real Servers running
Tomcat and nginx fallback server on LVS nodes. All works as expected
except ldirectord fallback server check. If I turn off all real servers
ldirectord add fallback server to LVS table and remove it after real
servers comes back. But ldirectord send email alerts about inaccessible
real server on 127.0.01. I check fallback server on LVS and it is
accessible from web browser. It seems like ldirectord does not remove
fallback server from some "servers list". I am not perl programmer, so
it is hard to me to patch ldirectord script. Workaround is manually set
emailalertfreq=0 but I think it is not the right way.
ldirectord.log:
