Hi all ,
I am using the 2 node cluster with drbd.
For sending the cluster packets & drbd packet I have connected the 3
cross cable between 2 server.
The IP and config is as follows :--
service mailbox1 mailbox2
Interface
---------------------------------------------------------------------------
1) drbd res0 10.10.10.10/16 10.10.10.20/16 eth1
2) drbd res1 10.10.10.30/16 10.10.10.40/16 eth2
3) Cluster Packet 10.10.20.1/16 10.10.20.1/16 eth5
cat /etc/hosts
10.10.20.1 mailbox1
10.10.20.2 mailbox2

*Question :-- *
While starting the cluster , the log are saying that the "*got nodejoin
message 10.10.10.10 & 10.10.10.20*"
where as the /etc/hosts are define with 10.10.20.1 <---> mailbox1 ,
10.10.20.2 <----->mailbox2
1) Why the cluster is not taking the IP 10.10.20.1 & 10.10.20.2 ( i.e
cross cable IPs. ) ?
2) Is it because my all cross cable IPs are in 10.10.x.x series , and
cluster is finding the nearest IP ( 10.10.10.10 & 10.10.10.20) for
communication ?
3) Do I need to take 172.16.x.x or some other IP series ?
