Corosync ring1


Active Member

I have a cluster of several nodes. Each of them have 4 NIC's. For redundancy, there are 2 bond of 2 NIC's.

bond0 = for public, management and corosync network. Connected to 2 TOR switches.
bond1 = for Ceph sync and backup. Connected to 2 CEPH switches.

The cluster network corosync ring0 is configured on a separated vlan on bond0. It is not recommended to create a corosync network on a network that is used for storage traffic, says the documentation.
For corosync redundancy, I would like to create ring1. Is it a option to use bond1 for this? I know it then is connected to the storage switches where Ceph syncs, but all for redundancy, or not?

What are your suggestions?


the recommendation say you should use a dedicated network for corosync.
In your case, create ring1 on bond1 brings more reliability.
Because corosync on a vlan is also not recommended
