Hello,
I'm testing a load balance environment with DR configuration.
That's my ldirectord.cf:
logfile="local0"
virtual = VIP:80
real = RIP:80 gate
real = RIP:80 gate
checktimeout = 10
scheduler = sed
netmask=255.255.255.224
protocol = tcp
checktype = connect
Load balance is on apache service. Shutting down on apache server ldirectord
sets the relative weight to 0. Correct!
When I restart apache ldirectord restore the real server but set it to masq.
Not Correct!
At this point I have to restart ldirectord to have all working again.
Better:
1. start ldirectord
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP VIP:http sed
-> RIP:http Route 1 1 2
-> RIP:http Route 1 1 2
2. stop one apache server
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP VIP:http sed
-> RIP:http Route 1 1 3
-> RIP:http Route 0 1 1
3. restore apache server
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP VIP:http sed
-> RIP:http Route 1 1 3
-> RIP:http Masq 1000 1 1
I cannot replicate this systematically, it's random. As I see in the system
log, when ldirectord does a correct restore I have :
Aug 20 13:07:47 ldirectord[15130]: Restored real server: RIP:80 (VIP:80)
(Weight set to 1000)
Aug 20 13:07:47 ldirectord[12279]: Restored real server: RIP:80 (VIP:80)
(Weight set to 1)
The first correspond to a masq directive, the second to a gate.
When restore is incorrect I have:
Aug 20 13:00:12 ldirectord[12235]: Restored real server: RIP:80 (VIP:80)
(Weight set to 1)
Aug 20 13:00:16 ldirectord[15130]: Restored real server: RIP:80 (VIP:80)
(Weight set to 1000)
Any suggestion? There is a way to say NEVER use masq directive?
Tnx
