[pve-devel] [PATCH manager 3/3] Fix #2422: allow multiple Ceph public networks

[Alwin Antreich]

Multiple public networks can be defined in the ceph.conf. The networks
need to be routed to each other.

On first service start the Ceph MON will register itself with one of the
IPs configured locally, matching one of the public networks defined in
the ceph.conf.
