Is ceph possible on 2 nodes?

Question

linux

Good evening!
there are only two nodes and they are spaced in different DCs and cluster storage is required.
I know that at least 3 nodes are required, and for ceph it’s 5 at all, but I met them on the network with two.
Is there any point in trying? or use just DRDB (but it crumbles at the slightest network failure.)?
storage is necessary for vertualok.
Thank you.

DRDB on a separate, dedicated network - in fact, you simply connect two machines with separate patches, that's all, nothing will ever crash.
