ipvsadm添加规则无效提示“Memory allocation problem”——LVM群集

现象

[root@localhost ~]# ipvsadm -a -t 20.0.0.11:80 -r 192.168.30.11 -m -w 1
Memory allocation problem

原因

是因为没有创建虚拟服务器，创建虚拟服务器后规则写入成功

[root@localhost ~]# ipvsadm -A -t 20.0.0.11:80 -s rr
[root@localhost ~]# ipvsadm -a -t 20.0.0.11:80 -r 192.168.30.11 -m -w 1
[root@localhost ~]# ipvsadm-save >/opt/123
[root@localhost ~]# cat /opt/123 
-A -t localhost.localdomain:http -s rr
-a -t localhost.localdomain:http -r localhost.localdomain:http -m -w 1
