Ceph is really cool, i also wanna use it in the future but i need way more disks for that :). Are those 25 worker nodes virtual machines? How did you attatch the disks to the ceph nodes?
I haven't used keepalived or haproxy before, but i quickly took a look at it. Do you mean i should setup 2 new vms which run keepalived an ha proxy?
While looking at keepalived i remembered reading about kube-vip https://kube-vip.io/. Couldnt this also help me with the issue? Since this also uses a vip and 1 node gets elected and its able to inform the network which node this is?
I doubt many are looking for 8-bay DAS, anything larger than 4-bay you are probably better off with NAS. Many DAS have limited RAID support, which can make having more drives more risky.
But i already have a computer that works well enough, isnt it a waste to completly replace it with a nas?
