Hi'

The below is in context of a hyperconverged ceph cluster as per chapter eight in the pve admin guide.

Ceph documentation https://docs.ceph.com/en/pacific/rados/configuration/network-config-ref/#ceph-networks tells that ceph global options public_network and cluster_network can include multiple networks. Say then that you have a pve ceph cluster, where each pve node has two bondings going to separate networks A and B, and say that you have included both of A and B in the ceph global options public_network and cluster_network. Then the following questions come to mind.

* Which network will a VM in the pve ceph cluster be using, A or B, when reading and writing data from and to the ceph cluster?

* Can ceph monitor processes be spread across A and B, 4 on each, say, for a pve ceph cluster with 8 nodes?

Best regards.

Thomas.
