[Samba] CTDB and LVS

[Leszek Szczepanowski]

Dears,

I wanted to have LVS VIP additionally to the DNS round-robin load balancing.
I have configured the following files on all my CTDB nodes:

/etc/ctdb/lvs_nodes:

[root at fs01 ctdb]# cat lvs_nodes
10.254.94.11
10.254.94.12
10.254.94.13
10.254.94.14
10.254.94.15
10.254.94.16

Those are internal IPs for the CTDB cluster (also used for GlusterFS
internal traffic).

/etc/ctdb/script.options:

# 91.lvs
CTDB_LVS_PUBLIC_IFACE=bridge0
CTDB_LVS_PUBLIC_IP=10.46.68.30

[root at fs01 ctdb]# onnode all ctdb scriptstatus

>> NODE: 10.254.94.11 <<
[...]
91.lvs               OK         0.004 Thu Dec 15 14:03:45 2022

>> NODE: 10.254.94.12 <<
[...]
91.lvs               OK         0.005 Thu Dec 15 14:03:56 2022

>> NODE: 10.254.94.13 <<
[...]
91.lvs               OK         0.005 Thu Dec 15 14:03:48 2022

>> NODE: 10.254.94.14 <<
[...]
91.lvs               OK         0.005 Thu Dec 15 14:03:48 2022

>> NODE: 10.254.94.15 <<
[...]
91.lvs               OK         0.005 Thu Dec 15 14:03:53 2022

>> NODE: 10.254.94.16 <<
[...]
91.lvs               OK         0.005 Thu Dec 15 14:04:05 2022

[root at fs01 ctdb]# ctdb lvs list
0 10.254.94.11
1 10.254.94.12
2 10.254.94.13
3 10.254.94.14
4 10.254.94.15
5 10.254.94.16

[root at fs01 ctdb]# ctdb lvs status
pnn:0 10.254.94.11     OK (THIS NODE)
pnn:1 10.254.94.12     OK
pnn:2 10.254.94.13     OK
pnn:3 10.254.94.14     OK
pnn:4 10.254.94.15     OK
pnn:5 10.254.94.16     OK

But actually, nothing happens.

[root at fs01 ctdb]# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
[root at fs01 ctdb]#

What I'm missing here?
