Hi all, i'm going to build an all-flash ceph cluster, looking around the existing documentation i see lots of guides and and use case scenarios from various vendor testing Ceph with replica 2x.
Now, i'm an old school Ceph user, I always considered 2x replica really dangerous for production data, especially when both OSDs can't decide which replica is the good one. Why all NVMe storage vendor and partners use only 2x replica? They claim it's safe because NVMe is better in handling errors, but i usually don't trust marketing claims :) Is it true? Can someone confirm that NVMe is different compared to HDD and therefore replica 2 can be considered safe to be put in production? Many Thanks Giordano
