6.2 Active and Standby IP Ports Are Configured on the
Quorum Server. After the Port in Use Is Down, the
Quorum Server Goes Offline. Why?
Question
The quorum server has two IP ports that work in active/standby mode and are on the same
network segment. After the port in use is down, why does the quorum server go offline?
Answer
By default, a quorum server does not have policy routes. It can only receive and send data via
one IP port although it has two IP ports on the same network segment. As a result, after the
port in use goes down, the other port cannot take over services.
Perform the following operations:
Step 1 Create a policy routing table for the quorum server.
In the CLI of the quorum server, run ip route add under any directory.
XXX@Linux:~# ip route add 192.168.0.0/16 dev eth5 table 20 XXX@Linux:~# ip route
add 192.168.0.0/16 dev eth6 table 21
In the preceding example:
l The IP addresses in the 192.168.0.0/16 segment receive and send data via the eth5 port. The routing table
l The IP addresses in the 192.168.0.0/16 segment receive and send data via the eth6 port. The routing table
Step 2 Add the active and standby IP ports on the quorum server to the policy routing tables.
In the CLI of the quorum server, run ip rule add under any directory.
XXX@Linux:~# ip rule add from 192.168.1.5 table 20 priority XXX XXX@Linux:~# ip
rule add from 192.168.1.6 table 21 priority XXX
In the preceding example:
l The active port whose IP address is 192.168.1.5 is added to table 20.
l The standby port whose IP address is 192.168.1.6 is added to table 21.
l The priority XXX of the active and standby IP ports must be the same.
l If either IP port is down, the policy routing table must be configured for it again.
Step 3 Check whether the policy routes are configured successfully.
In the CLI of the quorum server, run ip rule under any directory. If the following information
is returned, the configuration is successful.
XXX@Linux:~# ip rule
100: from 192.168.1.5 lookup 20
100: from 192.168.1.6 lookup 21
