Hi folks,
Does anybody know if there are any issues running Ceph with multiple L2
LAN segements? I'm picturing a large multi-rack/multi-row deployment
where you may give each rack (or row) it's own L2 segment, then connect
them all with L3/ECMP in a leaf-spine architecture.
For a PoC I have set up such a environment with IPv6. The cluster was
spread out over 3 racks.
Each rack had it's own /64 IPv6 subnet where the top-of-rack switch was
also a L3 router.
The /64 subnets all came from a larger /56 subnet so all clients only
had 1 route.
That worked just fine.
The point is, just make sure there is a Layer 3 route from all nodes to
each other.
I'm wondering how cluster_network (or public_network) in ceph.conf works
in this case. Does that directive just tell a daemon starting on a
particular node which network to bind to? Or is a CIDR that has to be
accurate for every OSD and MON in the entire cluster?
Thanks,
- Travis
