Not exactly self hosting but maintaining/backing it up is hard for me. So many “what if”s are coming to my mind. Like what if DB gets corrupted? What if the device breaks? If on cloud provider, what if they decide to remove the server?
I need a local server and a remote one that are synced to confidentially self-host things and setting this up is a hassle I don’t want to take.
So my question is how safe is your setup? Are you still enthusiastic with it?
What does your internal network look like for ceph?
40 ssds as my osds… 5 hosts… all nodes are all functions (monitor/manager/metadataservers), if I added more servers I would not add any more of those… (which I do have 3 more servers for “parts”/spares… but could turn them on too if I really wanted to.
2x 40gbps networking for each server.
Since upstream internet is only 8gbps I let some vms use that bandwidth too… but that doesn’t eat into enough to starve Ceph at all. There’s 2x1gbps for all the normal internet facing services (which also acts as an innate rate limiter for those services).
