Wrong IP in corosync.conf

[iwen]

Hi!

I just realized, that one of my nodes has a wrong ip. It is the ip of the storage network not of my managment. No idea how that could happen.
The quorum is ok and everything runs as expected since months. But I would like to change the IP to the correct NIC.

The cluster info at the GUI looks like this:
192.168.0.1
192.168.0.2
192.168.0.3
10.1.0.1

May I manually change the IP (10.1.0.1) inside the corosync.conf file to the correct existing IP of the correct NIC (192.168.0.4) and reboot or will my cluster be broken?

Thank you

You can manually change the node IP address following these instructions to edit corosync.conf carefully. Also, check your /etc/hosts file on each node and your DNS resolution to ensure names map to the correct IP.
