IP Range Correction

[infinityM]

Hey Guys,

I'm sitting with an issue, we replaced some of our servers in our cluster... And somewhere we made a mistake..Can someone please help me. We would like the public IP range to be the 129.232.156.xx range, and the ceph data sync ip range 10.161.0.xx

The reason obviously being that corosync does not have such high latency...

So 2 questions...

Question 1:
pvecm status returns the following:
Membership information
----------------------
Nodeid Votes Name
0x00000001 1 10.161.0.100
0x00000002 1 129.232.156.16
0x00000003 1 129.232.156.20
0x00000005 1 10.161.0.104 (local)

How can I correct the range so that they're on the same range?

Question 2:
How can I check that the data sync is on the 10.161 range, and the live IP's are on the 129.232 range, and if not correct it safely?

I highly appreciate any advise

Addresses are configured in /etc/pve/corosync.conf - correct this file accordingly. When correcting this file increment also its version number (tag "config_version").

Thank you I have. What would happen if the version number is not incremented? Cause mine wasn't although it was changed...

Is suspect my ip ranges have ceph and proxmox corrosync syncing over eachother cause whenever ceph runs high all servers become unresponsive and only show grey question markes in PM UI...
How can I check though #StressedOut

It is strongly recommended to have a network used exclusively for corosync cluster (and another one for ceph).
