I have a small ceph cluster consisting of 4 Ubuntu 20.04 osd servers mainly serving rbd
images to Cloudstack kvm cluster. The ceph version is 15.2.9. The network is done in such
a way that all storage cluster is ran over infiniband qdr links (ipoib). We've got the
management network for our ceph servers and kvm over ethernet (192.168.1.1/24) and the
ipoib storage network 192.168.2.1/24. We are in the process of updating our cluster with
new hardware and planning to scrap the infiniband connectivity altogether and replace it
with 10gbit ethernet. We are also going to replace the kvm host servers too. We were
hoping to have minimal or preferably no downtime in this process.
I was wondering if we could run the ceph services (mon, osd, radosgw) concurrently over
two networks after we've added the 10G ethernet? While the upgrades and migration
taking place, we need to have the ceph running over the current ipoib 192.168.2.1/24 as
well as the 10G 192.168.3.1/24. Could you please help me with this?
