I'm working on the specifications for a very small Ceph cluster for VM images (OpenStack/QEMU-KVM/etc).
I'm being asked to justify sticking with the default redundancy levels (size=3, min_size=2) rather than dropping them to
size=2, min_size=1.
Can someone help me articulate why we should be keeping 3 copies, beyond "it's the default"?
